The species bubalina in Argentina in 1976 was introduced in 1300 animal numbers, which were mostly aimed at the<br />

northeast region; from there the production experiment a rapid increase, reaching at present to establish an amount<br />

close to 100 mil head. In this context, the province of Formosa is one of the provinces with the highest number of<br />

animals, resulting in a productive part in the scheme and development priorities in their various skills: meat, milk,<br />

leather.<br />

In order to diversify and optimize the use of technology, the Santa Ursula incorporates special buffalo milk with a<br />

particular scheme, coordinating with the university (Holando Breeders Association) and Breeders Association Argentina<br />

Buffalo to start testing production. Estimated parameters in dairy cattle bubalino (Bubalus bubalis) in a subtropical<br />

region of the farms American (Formosa, Argentina) The soil characteristics are very different, where you can find low hills,<br />

high mountains, land with natural pastures and implemented according to the topography and soil type. What will define<br />

the landscape where the floris production. The herd consists of animals breed Murrah, Mediterranean and jafarabadi.<br />

Those who were selected from a herd of buffalo 1500. The criterion for selection is given by age, docility, phenotypic<br />

characteristics of a productive (mammary gland) and the physiological status (pregnant).The values found for milk<br />

production averaged 1.907 ± 0492 and 7.463 results and 3.616 ± 1.415 ± 0.675 of fat and protein respectively. This<br />

indicates that the individual production demand greater investment in technology such as genetics, nutrition, technology<br />

and milking facilities. The behavior of solids is a correlation between levels of milk production and its corresponding<br />

value of fat and protein. Expressed high levels of milk production with low percentages of fat and protein.<br />

Abstract<br />

The main objective of present investigation was to study the effect of lactation stage and animal’s breed on physicochemical<br />

properties of milk from buffalo. The experiment was carried out from May to September, 2008, in the Três Irmãos<br />

farm, located in the Maiquinique (Bahia, Brazil).The follow physicochemical parameters were determined: total acidity<br />

and pH, density, cryoscopy, which indicated that there was not interaction between breed and lactation stage.<br />

INTRODUCTION<br />

Key words: Buffalo Milk, Lactation Stage, Physicochemical Characteristics.<br />

The importance of food science and technology for improving the human beings quality of life is highlighted by the<br />

rising search for healthy food, with high nutritional value, available and accessible to people. With this, the investigation<br />

of alternative food sources has been the subject of extensive researches in the last decades. Buffalo’s milk is<br />

promising in this context, since it has a superior nutritional value due to the high levels of fat, protein and minerals<br />

(specially calcium and phosphorus), that can be consumed in natura and may be used as raw material for producing diary<br />

products, varying in accordance to each regional culture 1, 2 savu . Moreover, buffalos are extremely rustic and demonstrate a<br />

high adaptation capacity, being able to survive in diverse environments with huge weather variations, relief and vegetation,<br />

so growing them is very economically feasible 4-3,5-4 . The data found regarding buffalo’s milk characteristics are very<br />

varied, since several factors influence the physicochemical properties 6, 5-8, 6 . In this context, the aim of this work was to<br />

evaluate the quality of milk from buffalo herd raised in the Bahia southwest, concerning physicochemical characteristics,<br />

as well as factors that influence, such as the lactation stage and the animal’s breed.<br />

MATERIALS AND METHODS<br />

The experiment was carried out from May to September, 2008, in the Três Irmãos farm, located in the Maiquinique (Bahia,<br />

Brazil). Twenty four animals were separated, according to extern characteristics, 12 were of the Murrah breed and 12 of<br />

the Jafarabadi breed. Animal’s food was pasture with Brachiaria Decumbens, with mineral salt supplement available.<br />

Buffalos of the same race were subdivided in three groups, four animals each. One liter of milk was sampled from every<br />

animal. Samples from animals of the same group were mixed, forming a composed sample. Thus, the composed samples<br />

were collected during the lactation, at the beginning (approximately one month after lactation), in the middle (fifth<br />

month of lactation) and at the end (near the ninth month of lactation).The follow physicochemical parameters were<br />

determined: total acidity and pH, density and cryoscopy. For statistical analysis, the results obtained were treated using<br />

the totally random experimental outline with a 2 x 3 factorial design, two races (Murrah and Jafarabadi) and three<br />

lactation phases (beginning, middle and end), with three replicas for each experiment. To study the effect of race,<br />

lactation phase and the interaction between race and lactation phase, the results obtained were treated in SAEG,<br />

according to statistical methods, using the variance analysis and comparison tests among averages (Tukey), with 5%<br />

probability.<br />

RESULTS AND DISCUSSION<br />

According to the results obtained for the physicochemical characterization of buffalo’s milk (Table 1), it was found that<br />

there was no interference statistic at 5% probability of breed and lactation stage studied in relation to pH, acidity,<br />

cryoscopy point and density.<br />

Average followed by the same letter, lower case on the line to breed and capital letter in the column for lactation stage,<br />

don’t differ (P>0.05) by F and Tukey tests.<br />

There was no difference (p> 0.05) in acidity and pH during the three stages of lactation, however, noted that these<br />

parameters varied between Murrah and Jafarabadi breed. Jafarabadi breed showed higher pH (6.93) and lowest Dornic<br />

values (13.8 °D) when compared with the results of the Murrah which presented pH 6.79 and acidity of 16.3 °D.<br />

Regarding the cryoscopy point determined in Hortvet degrees, we identified a significant difference (p 0.05) between the results<br />

of the milk samples of buffaloes in early (-0.535 °H), mid (- 0.539 °H) and late (-0.542 ° H) lactations. The density,<br />

it is related to fat and solids not fat. There was no significant difference (p> 0.05) between breeds and between<br />

lactations stage. The results obtained may contribute for establishing quality control standards of buffalo’s milk produced<br />

in the Southwest Region of the Bahia State.<br />

Abstract<br />

The present study was conducted on fourteen winter born buffalo calves to establish the developmental changes in<br />

various energy substrates and their relation to delayed colostrum intake. Blood samples were collected from these calves<br />

at 1, 2, 4, 8 and 24h after birth and subsequently once on day 7, 15, 30, 45, 60 and 90 and were analyzed for glucose,<br />

fructose, lactate, pyruvate and alkaline phosphatase. Colostrum was fed to these calves 8h after birth. Fructose was found<br />

to be an important energy source at birth (37.90±3.50 mg%) and its level registered a continuous fall on first day<br />

the intermediates of energy metabolism, have also been documented in newborn cattle calves post birth (Chand et al,<br />

1979). However, the changes that may occur in buffalo neonates on account of its poor survivability after birth continues<br />

to be the focal point of physiological investigations. The altered energy requirements post birth both in terms of<br />

thermolysis and thermo genesis have got many correlates, which need to be put to order in this species. This investigation<br />

was an attempt to bring out the chronological changes in energy substrates in response to delayed colostrum intake<br />

in buffalo calves post birth in winter season.<br />

MATERIALS AND METHODS<br />

Fourteen buffalo calves born during winter season irrespective of their time of birth with no evidence of health disorder<br />

were included in this study. Immediately after birth, these calves were removed from dams and were housed in a shed<br />

open from one side where they were allowed to move freely. The maximum temperature in the shed averaged 19.2±1.13°C<br />

while the minimum was 7.4±1.05°C. The relative humidity ranged between 50-90% during the entire period of study. The<br />

fetal fluid adhering to the body surface of the calves after birth was quickly dried with towels. These calves were assigned<br />

to first blood collection with in an hour of their birth by venipuncture from the jugular vein posing minimum disturbance<br />

to them. The blood was drawn into heparinised and nonheparinised vacuum tubes. Subsequently, the blood was<br />

collected at 2, 4, 8 and 24h. The calves received the first colostrum 8h after birth. The next feeding was done 12h after<br />

the first one. After this, the calves were fed colostrum twice a day for next four days and were subsequently shifted to milk<br />

feeding as per normal practice. The blood samples were also drawn on day 7, 15, 30, 45, 60 and 90 post birth once a day<br />

prior to a.m feeding. Nonheparinised samples were allowed to stand at room temperature for 20 min for clot formation.<br />

Serum was separated by centrifuging the samples at 3000 rpm for 20 min and stored at 4°C till the estimation of alkaline<br />

phosphatase. The heparinised blood was deproteinised using different deproteinising agents for analyzing different<br />

energy substrates viz 5% ZnSO4 and 4.5% Ba(OH)2 for the estimation of glucose and lactic acid; 10% ZnSO4 and 0.5N<br />

NaOH for fructose; 10% TCA for pyruvic acid immediately after blood collection. The filtrates were stored at 4°C until<br />

analysis, which was carried out with in 8h of collection of blood.<br />

The data was statistically analyzed for means and S.E. Analysis of variance (ANOVA) was applied to study changes on day<br />

1 between different hours by the calves. ANOVA was also applied to the data obtained till day 90 post birth.<br />

RESULTS AND DISCUSSION<br />

Glucose<br />

High levels of glucose (85.33±10.30 mg %) were found at birth (sample collected with in 1h, Table 1) in buffalo calves<br />

despite the fact that these calves were not offered colostrum. These further registered a significant rise (P


<strong>MILK</strong> <strong>PRODUCTION</strong><br />

The values obtained in this investigation for the period immediately after birth are in agreement with those reported by<br />

Daniels et al, 1974 for cattle calves. Others have reported comparatively lower values (Comline and Edwards, 1968; Young<br />

et al, 1970; Chand et al, 1979). In addition to enhanced glycogenolysis and colostrum intake other factors that also<br />

seemed to be involved in regulating glucose homeostasis in blood during this period included the enzyme phosphofructokinase,<br />

hormones viz cortisol and thyroxine and cold temperature. Phosphofructokinase is involved in preparatory<br />

phase of glycolysis and is a rate-limiting enzyme for promotion of glucose use in the cell. After birth due to ATP<br />

inhibition of phosphofructokinase (Underwood and Newsholme, 1965), the glucose catabolism is slowed down which<br />

results in an increase in peripheral glucose. Sano et al (1979) obtained a positive correlation between blood glucose and<br />

thyroxine. Massip (1980) found a positive linear correlation between glucose and cortisol. Therefore, carbohydrate<br />

metabolism and the pituitary-adrenal-cortical system played an important role during this period of adaptation. The post<br />

8h increase in glucose in all the calves is attributed to colostrum feeding because of the conversion of lactose to glucose<br />

and its subsequent absorption from intestinal tract. Later on the levels of glucose tended to fluctuate nonsignificantly<br />

on different days (Tab 2). Relatively high levels of glucose during the entire period of study in these calves suggested an<br />

enhanced glucose exclusion from the tissues, an increase in use of NEFA and ketone bodies and action of Cori cycle which<br />

mobilizes glucose from the liver to peripheral circulation and returns lactate to liver for resynthesis of glucose (Bergman,<br />

1971).<br />

Fructose<br />

Fructose registered maximum value at birth, the average being 37.90±3.50 mg%, which steadily and significantly decreased<br />

till 24h (Table 1;P


546<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

The high levels of lactic acid after birth have been associated with either excessive hypoxia or struggling at parturition<br />

(Comline and Silver, 1968) through an increased adrenaline concentration, which appears to be effective in raising the<br />

lactate concentration of the blood in the calf during first 24h of life. The levels increased from 8 to 29 mg% upon<br />

intravenous adrenaline injection (Graf and Petersen 1953). Bianca and Findlay (1962) also observed an increase in lactic<br />

acid by stimulation of sympathico- adrenal system causing an increased adrenal activity.<br />

The increased concentration of lactic acid and pyruvic acid postbirth in the blood reflected an increased rate of glycolysis<br />

in muscles to meet energy demands. The disappearance pattern of glucose and fructose from blood also indicated<br />

the same. Jedlica et al (1975) also opined that at low temperature increased utilization of glucose through glycolytic<br />

pathway would elevate the levels of lactic acid in the process of maintaining body temperature.<br />

The high levels of lactate could also be efficiently utilized as an energy system by the brain on day 1. Among insulin<br />

induced hypoglycemic neonate calves (Comline and Edwards, 1968) an increase in lactate concentration during first 24h<br />

after birth was obtained. Among older calves also in which lactate rose substantially (Gardiner, 1980) it was shown that<br />

there was no net uptake of lactate by liver. A few other studies (Oldendorf, 1971; Nemoto et al., 1974) have indicated the<br />

existence of stereo specific saturable carrier system for lactate at blood brain barrier.<br />

Alkaline Phosphatase<br />

The serum alkaline phosphatase activity with in 1h post birth was 4.28±0.45um/ml. The activity subsequently did not<br />

present variations for first 8h. But after colostrum feeding the levels increased significantly (p

To see the effect of different physiological stages and mangemental practices on amount of milk somatic cells secreted<br />

from udder of Murrah buffaloes. Milk was collected from 64 Murrah buffaloes which were divided into various groups<br />

according to their stage of lactation, parity, colostrums collected, body weight, body condition score, season, milking<br />

practices and fractionated. There were non-significant changes in milk SCC in early, mid and late lactation. Milk SCC<br />

increased non-significantly from 1 st to 4 th parity. Milk SCC were significantly higher (P

also been represented in Table 1. Individual milk samples pooled for all four quarters from the entire animal were collected<br />

separately. About 100 ml of milk was collected aseptically in clean milk bottles. The samples were brought to the<br />

laboratory immediately after collection and placed in refrigerator till use. For SCC the slides were prepared within one<br />

hour of collection of milk samples. Milk SCC was estimated microscopically 3 . The SCC were measured under the microscope<br />

with a magnification of 100 X 10 in 200 fields and average number of cells per field was multiplied by the microscopic<br />

factor (8.81134633). The microscopic factor was determined by using ocular and stage micrometer. Somatic cell counts/<br />

ml of milk (lakh) = Average cells count in one field x 8.81134633. The data obtained were subjected to statistical<br />

analysis using least square analysis of variance.<br />

RESULTS AND DISCUSSION<br />

Mean ± SE values of SCC (10 5 cells /ml) in milk during different physiological stages and under different managemental<br />

practices have been presented in Table 1. The values of milk SCC were within range 2 as reported in Murrah buffaloes. There<br />

were non-significant changes in Milk SCC in early, mid and late lactation. Little change in milk SCC has also been reported<br />

with stage of lactation in cows 5 . On comparing the effect of parity on milk SCC, it was observed by milk SCC increased<br />

non-significantly from 1 st to 4 th parity. The reason may be that SCC is positively correlated with milk production and milk<br />

production increases with an increase in parity. Milk SCC were significantly higher (P


<strong>MILK</strong> <strong>PRODUCTION</strong><br />

There was a decrease in milk SCC in normal milk from that of fore milk which again increased in stripping. A higher<br />

concentration of SCC in the stripping may be due to the sloughing off of more cells into milk and an increase in fore milk<br />

SCC may be due to the presence of pathogens towards the teat end which may promote movement of somatic cells towards<br />

it.<br />

Our results indicate that as in cows, milk SCC also varies in the milk of Murrah buffaloes under different physiological<br />

stages and managemental practices. Although, buffaloes possess a powerful defence mechanism against mastitis due to<br />

their tight teat sphincter 7 and long narrow teat canal which can be expected to effectively prevent micro-organisms from<br />

invading the udder 9 . But with change in management systems (increased feeding and introduction of machine milkings)<br />

an increase in milk SCC is there which may Increase the chance of mammary infection. Therefore, buffaloes of high parity,<br />

producing more milk and those exposed to summer stress require proper care and management to maintain their milk<br />

production.<br />

Abstract<br />

This study aimed to evaluate the effects of somatic cell count (SCC) on buffalo milk. Samples were collected monthly from<br />

156 Murrah buffaloes during lactation, in 4 production systems (tropical pasture with supplementation), in Brazil. The<br />

SCC was determined by flow cytometry, using the Somacount 300. The fat, crude protein and lactose were determined by<br />

infrared light reading absorption, using the Bentley 2000 (Bentley Instruments). The SCC range in milk was (x 1.000<br />

cells): Group 1 – until 250; Group 2 - more 250 to 450; Group 3 – more 450 to 750; Group 4 – more 750 to 1.000; Group<br />

5 - more 1.000. The larger frequency of samples was observed in the Group 1 (89.7%). In the Group 2 was observed 4.6%<br />

of samples. In turn, in the Group 3 was 1.8%, in the Group 4 was 0.7%, and in the Group 5 was observed 3.2% of milk<br />

samples. Milk components such as fat, protein and lactose were not affected in spite of a decrease in their concentration.<br />

Perhaps, this result is due to the small number of samples in 3, 4 and 5 Groups. However, significant effect of SCC on the<br />

solids was observed. Most total solids concentration was observed in the Group 1 (17.1±1.71%) did not differ from Group<br />

2 (16.5±1.45%) and Group 3 (16.8±2.09%), however was observed statistical effect from intervals 4 (15.8±2.43%) and<br />

5 (14.5±2.39%). In the 2, 3 and 4 Groups was not find statistical difference, however, they differ in the range 5. The SCC<br />

did not affect the composition of buffalo’s milk.<br />

INTRODUCTION<br />

Key-words: crude protein; fat, lactose, milk<br />

Brazilian milk is regulated by the Normative Instruction 51 (IN 51) 1 . This Instruction determines the maximum values of<br />

milk components, varying from region to region. Therefore, at the Northeast, the Somatic Cell Count (SCC)/mL must not<br />

be superior than 1 million, until July 2010. Between July 2010 and July 2012, this count must be lower than 750 million<br />

SC/mL and from July 2010, it must be lower than 400 million SC/mL (1). Tracking is important for controlling mastitis in<br />

herds, due to the economic loss caused by the disease 2,3 . Mastitis positively correlates to SCC in milk, which turns this<br />

test widely accepted as a determinant in milk quality. There is not widespread information about SCC in buffalo‘s milk in<br />

Brasil.<br />

Therefore, the objective of this study was to evaluate the SCC of milk buffalo and its influence on its components.<br />

MATERIAL AND METHODS<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

One hundred and fifty six samples of buffalo Murrah were collected, monthly, during their lactation period on 2002, from<br />

grazing cattle with supplementation, in Brazil. Samples of 50 mL of raw milk were individually collected, after milking, in<br />

plastic recipients of 2-bromium-2-nitroprophane-1,3diol (Bronopol) and kept cooled in isothermal boxes with recycled<br />

ice. Somatic Cell Count (SCC) was conducted by flow cytometry, using the Somacount 300. The fat, crude protein and<br />

lactose were determined by infrared light reading absorption, using the Bentley 2000 (Bentley Instruments). The SCC<br />

range in milk was (x 1.000 cells): Group 1 – until 250; Group 2 - more 250 to 450; Group 3 – more 450 to 750; Group<br />

4 – more 750 to 1.000; Group 5 - more 1.000. The results were analyzed by Student-Newman-Keuls test, at 5% probability,<br />

using SAS (4).<br />

RESULTS AND DISCUSSION<br />

It was observed that 96,8% of samples (Table 1) were within the limits established by Brazilian Legislation. More important,<br />

89,7% of samples presented SCC lower than 250 thousand. According to the chronogram of IN 51, over 90% of<br />

buffalo milk producers will follow establishments from July 2012. As is it possible to observe, there was not a significant<br />

effect (P>0,05%) of SCC for fat, total protein and lactose test. However, total solids content differed (P

Abstract<br />

The observation and measurements of 118 buffaloes of Murrah, Nili-Ravi and local breeds maintained by the farmers at<br />

three villages viz Goharni, Badheo and Bhainswal of district M. Nagar (U.P.) India for a period of two months i.e. from 1st<br />

July to 31st Aug. 2005 were taken. Four observations on each milking trait were taken continuously on each buffalo.<br />

Least squares technique was used to study the effect of breeds, parity, stage of lactation, shape of teats, let down with<br />

or without calf, method of milking, fodder feeding concentrate feeding and shift of milking. Out of 118 buffaloes under<br />

investigation 51 buffaloes were Murrah or Murrah type, 20 Nili-Ravi and 47 were non descript. The overall least squares<br />

means for milk let down time, actual milking time, milk yield per milking and milk flow rate were found as 154.99±5.56<br />

seconds, 289.85±12.20 seconds, 2994.35±106.52 gms and 10.50±0.29 gms/second, respectively. The milk let down<br />

same purpose in village conditions, where milk production records of animals are not available. Hence it is not easy to<br />

select the best animal. It is therefore essential to have some idea of the indications of high yielding animals. Few reports<br />

available in literature have indicated that there is positive association between milk yield and milk flow rate. Therefore<br />

it was thought to plan the present investigation to arrive at some important information which can be used for selection<br />

of the animals at farmer’s conditions, where data of milk recording is not available.<br />

MATERIALS AND METHODS<br />

The present study was conducted on the observations and measurements of 118 buffaloes of Murrah, Nili-Ravi and local<br />

breed of buffaloes maintained by the farmers at three villages of districts M.Nagar (U.P.), India for a period of two months<br />

i.e. from 1 st July to 31 st August, 2005. Four observations on each milking trait i.e. milk letdown time, actual milking time,<br />

milk yield per milking and milk flow rate were taken continuously on each buffalo. The buffaloes under the study belonged<br />

to different stage of lactation and different parities. These buffaloes were milked twice a day (morning and evening) by<br />

different methods of hand milking and calves were allowed to suckle their mother. The buffaloes without calf due to death<br />

of the calf were stimulated by hands and oxytocin injection for milk let down. The milking was performed by full hand<br />

method and by thumb-in method using both hands from beginning of milking till the end of stripping. The animals under<br />

study had all four teats functional.<br />

The least squares model 7 was used to study the effect of breeds, parity, stage of lactation, shape of teats, letdown with<br />

or without calf, method of milking, fodder feeding, concentrate feeding and shift of milking. The association among<br />

milking traits was calculated by estimating the correlation coefficients among milking traits.<br />

RESULTS AND DISCUSSION<br />

Milk letdown time: The letdown time of buffaloes, if reduced, we can save expenditure involved in milking process.<br />

Mostly, early letting down reflex helps in quicker and fuller evacuation of alveolar milk from the udder of buffaloes (Aliv,<br />

1969). The overall average of milk letdown time observed in the present investigation was 154.19±5.56 seconds (table<br />

1). This traits was significantly (P

Table 2. Least-squares analysis of variance (mean squares only) of milking traits and milk yield.<br />

Milk yield per milking: The overall average of milk yield per milking on test day was 2994.35 ±106.52 gms (table1).<br />

Whereas, higher average milk yield per milking i.e. 3402±59 gms was reported earlier 6 . The differences in milk yield per<br />

milking due to parity order and stage of lactation were highly significant and due to shape of teats and method of<br />

milking were significant (table 2). Earlier workers 10 also noticed significant effect of parity order and stage of lactation<br />

on milk yield per milking. Significantly higher daily milk yield in un-weaned buffaloes in compression of weaned buffaloes<br />

has been reported 12 .<br />

Milk Flow Rate – The milk flow rate from udder is an important management trait of buffaloes. Earlier report 11 suggested<br />

that milk flow rate can be used in evaluating dairy animal for milk production under field condition where milk recording<br />

is not practiced. The overall average of milk flow rate under hand milking was 10.50+0.29 gms/seconds (Table 1). Almost<br />

similar milk flow rate was observed earlier 2 in buffaloes. Where as the present estimate was lower as compared to the<br />

average milk flow rate (15 gms/second) reported by others 8 . The least –squares analysis of data (Table 2) showed that<br />

breed, parity order, stage of lactation, time of fodder feeding and trend of concentrate feeding had highly significant<br />

effect on milk flow rate. Earlier studies 3,9,10 reported significant effect of parity order and stage of lactation on this trait.<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Buffalos have become an economically viable source of protein due to their adaptability, precocity and longevity. Human<br />

and dairy cattle interact on a daily basis in routine activities, which may have positive or negative effects on production<br />

and animal welfare 1 . Studies of animal behavior have aimed to describe how food traits and/or handling practices relate<br />

to behavioral aspects, linking behavioral changes as indicators of animal comfort with productive aspects 2 . The objective<br />

of this study was to assess the<br />

behavior of buffaloes in the milking parlor under the influence of strangers’ being present during the monthly Milk<br />

Control, throughout the first three lactation months, and verify how that affected the production of Murrah animals.<br />

MATERIAL AND METHODS<br />

Murrah buffaloes (N=24) participating in an improvement program at Recôncavo of Bahia, Brazil, were monitored during<br />

the first three months of Milk Control (CL) for their behavior in the milking parlor, in the presence of strangers.<br />

Throughout the study, there was no change in the routine followed by animals. The milking parlor is comprised of two<br />

lines with eight animals in either side. After being milked, the animals are allowed to eat for approximately one hour the<br />

concentrated mixture of wheat flour and grains, combined to suit the lactation phase.<br />

The behavioral variables monitored through direct observation were: permanence in the milking parlor (TPOR) – duration<br />

of the time the animal remained in the milking parlor, in minutes; milking time (TOR) – how long the animal was milked<br />

for, in minutes; rumination (Ru) – whether the animal ruminated in the milking parlor (equal to 1) or not (equal to 0);<br />

defecation (Def) - whether the animal defecated in the milking parlor (equal to 1) or not (equal to 0); miction (Mic) –<br />

whether the animal urinated in<br />

the milking parlor (equal to 1) or not (equal to 0); reactivity (Reat) – animal limb movements in the milking parlor (1 =<br />

remained still; 2 = limbs raised up to 15cm above the ground; 3 = limbs raised more than 15cm above the ground); stress<br />

level (Nest) – equal to 1 for a restless animal, 2 for a slightly restless animal, and 3 for a calm animal). In addition, records<br />

were made of milk production on the date (PLO), milk production one week later (PLP), and class (CAT1 for first parturition<br />

and CAT2 for multiparous). Descriptive statistics for variables TPOR (in minutes), TOR (in minutes), PLO (in kg/day)<br />

and PLP (in kg/day) were calculated by the Statistical Analysis System software (SAS,<br />

2002), as was the Spearman correlation between the production means when strangers were present in and absent from<br />

the parlor.<br />

RESULTS AND DISCUSSION<br />

The mean TPOR was 21, and the mean TOR was seven minutes. The mean PLO was 7.54 kg, whereas the mean PLP was<br />

10.06kg. Only one animal defecated and three urinated during the first CL (Figure 1). Approximately 50% presented Reat<br />

mode equal to 1, 33% equal to 2 and only 17% equal to 3, with 80% in CAT1 and 58% in CAT2 showing little or no<br />

restlessness during milking. As for the modal Nest, only two CAT2 animals were rated as restless, 40% as slightly restless<br />

and 50% as quiet. According to a previous study 1 , a high rumination rate, little reactivity during milking, reduced<br />

defecation and miction increase productivity and milk quality.<br />

Abstract<br />

This study aimed to evaluate the effect of different feeding systems on milk fat quality of Murrah buffaloes. Forty Murrah<br />

buffaloes from 5 different Brazilian farms (n=8 animals/farm) were used. Milk samples were collected monthly throughout a<br />

single lactation, and fatty acid profile was determined by gas chromatography. Milk fatty acid profile was used to calculate the<br />

nutritional quality of milk fat according to the following indices: atherogenicity index (AI); thrombogenicity index (TI); omega<br />

6/omega 3 (n6/n3) ratio and desirable fatty acids (DFA). Statistical analyses were performed using PROC Univariete from 7 .<br />

The smallest AI (1.49±0.43) was observed in milk fat from Buffaloes raised in the Farm 3. No differences among farms were<br />

observed for TI and n6/n3 ratio. However, DFA differed among farms, with milk fat of Buffaloes from Farm 3 showing the highest<br />

values (47.17%). Our results showed that nutritional quality of milk fat from Murrah Buffaloes is influenced by different<br />

feeding systems.<br />

INTRODUCTION<br />

Key words: milk fatty acids, atherosclerosis, human health, Buffaloes, nutrition<br />

Due to health concerns, much attention has been focused on milk fat composition. The index of atherogenicity (AI) basically<br />

describes the ratio between pro and anti-atherogenic fatty acids 1 . In milk and dairy products, the value found is around 2<br />

however AI=1,5 is considered low and 2,5 is high 2 . The index of thrombogenicity (IT) considers the major saturated fatty acids<br />

as pro-thrombogenic, while the unsaturated ones are considered anti-thrombogenic 1 . Another index used in nutritional assessment<br />

of fats and oils is the n6/n3 ratio. According to 3 this ratio must be £ 4.0. The objective of this work was to evaluate the<br />

AI, TI, n6/n3 ratio and desirable fatty acids (DFA) in milk fat from Buffaloes raised under different feeding systems.<br />

MATERIAL AND METHODS<br />

This trial was carried out on five commercial farms located at Sarapui (23º38’28” S and 47º49’38” W) and Pilar do Sul<br />

(23º48’44” S and 47º42’29” W) cities, state of São Paulo, Brazil. In each farm, milk samples from eight buffaloes were<br />

collected from April to November 2002. Milk samples were stored at -20º until analyzed for fatty acid composition. The nutritional<br />

management adopted in each farm was as follow: Farm 1- buffaloes were maintained in feedlot and fed corn silage and wet<br />

brewers grain as the main sources of forage and concentrate, respectively; Farm 2 - buffaloes were maintained in feedlot and fed<br />

corn silage, either chopped fresh grass (Pennisetum purpureum) or sugarcane (Saccharum officinarum), and wet brewers<br />

grain as the primary concentrate source; Farm 3- buffaloes were maintained on pasture (Brachiaria decumbens) supplemented<br />

with sugarcane and wet brewers grain as the primary concentrate source, Farm 4- buffaloes were maintained on pasture<br />

(Brachiaria decumbens) supplemented with corn silage and wet brewers grain only in April, October and November; Farm 5buffaloes<br />

were maintained on pasture (Brachiaria ruziziensis) supplemented with grass silage (B. ruziziensis) and concentrate<br />

(whole cottonseed, citric pulp and urea) plus wet brewers grain. Milk fat from samples was extracted according to 4 and fatty acids<br />

methylation was performed as described by 5 . Fatty acids methyl esters were analyzed by gas chromatograph as described 6 .<br />

Atherogenicity index (AI) and thrombogenicity index (TI) were calculated according to 1 : AI = ((C12:0 + (4 x C14:0) +<br />

C16:0)/ÓAGMI + Ón6+ Ón3); TI = (C14:0 + C16:0 + C18:0)/{(0.5 x ÓAGMI) + (0.5 x Ó n6 + (3 x Ó n3) + (Ó + Ón3 + Ó<br />

thirty-eight animals at a herd (Bahia state, Brazil). The fatty acid profile was performed by gas chromatography and the<br />

statistics analysis was carried out using Test t of Student for matching data at 5% significance. Higher concentrations of<br />

saturated fatty acids in early and late lactation were observed. In turn, there was an increase of monounsaturated fatty acids<br />

concentration. In assessing the nutritional quality of lipid fraction, the buffalo’s milk from the late stage lactation was more<br />

nutritionally adequate food intake.<br />

INTRODUCTION<br />

Milk and dairy products may be designated as functional food. The main characteristic of ruminant milk is its content of<br />

short and intermediary fatty acid chains, which are related to aroma, flavor and fluidity. Approximately 2% of fat is<br />

composed of polyunsaturated fatty acids and 70% of saturated. However, less than 40% are classified as hazardous (C 12:0 ,<br />

C 14:0 e C 16:0 ) 2 . According to 3, the fatty acids which appear in biggest proportions in buffalo milk are, in order, C 16:0 , C 18:1 ,<br />

C 18:0 e C 14:0. Therefore, the objective of this work was to evaluate the lipid profile of Murrah buffalo milk at the beginning<br />

and in the end of the lactation period.<br />

MATERIALS AND METHODS<br />

Thirty eight sampled were obtained from Murrah buffalo through mechanic milking, exclusively grazing (Brachiaria decumbens)<br />

buffalo at a commercial farm located at Uruçuca, BA, Brazil. Samples were collected on July and October, 2007, months that<br />

characterize the initial and final stage of lactation, respective. Lipid extraction for determining fatty acid profile purposes was<br />

conducted following procedures established by 4 and methylation step was conducted following procedures 5. Fatty acid profile<br />

was determined by gas chromatography using silica capilar column (100 m X 0,25 mm X 0,2 mm; Supelco) and flame ion<br />

detector, with hydrogen as the carrying gas.<br />

RESULTS AND DISCUSSION<br />

Lactation period has influenced saturated, monounsaturated and polyunsaturated fatty acid profile of milk (Table 1). At<br />

the beginning of lactation, milk presented the highest proportion of saturated fatty acids if compared to the final stage.<br />

This profile is strongly influenced by the lactation period due to the need of mobilizing lipid storages at the beginning<br />

of lactation. The last contributed for the presence of, mainly, saturated fatty acids in ruminant milk. In the end of<br />

lactation, there was an increase on the concentration of monounsaturated fatty acids.<br />

The result for the set of hypercholesterolemic fatty acids (C12:0, C14:0 e C16:0) were lower than those reported by 6. In<br />

the end of lactation period, there was a superior average of desirable fatty acids (unsaturated + C18:0), 49,41%, showing<br />

superiority, from a nutritional point of view, of the milk obtained in the beginning of lactation period (45,63%).<br />

Abstract<br />

From the end of the 2004, the morphological evaluation system of the Italian Mediterranean Buffalo population have<br />

been changed from a subjective assessment of animal’s strengths and weaknesses, to a linear evaluation system. This new<br />

system take into account animal morphological defects to assess the real impact of those defects on the buffalo population<br />

for selection purposes. In fact, the new form for recording the scores of the linear evaluation system, contains a<br />

blank for reporting various defects. The linear system is an objective method of assessment that allows to picture the<br />

animal indicating and quantifying the degree of biologic measures. The main purpose of this study was to identify the<br />

frequency of each alteration or obvious morphological defect of the animal. It was studied the incidence of each defect<br />

on the buffalo population. Moreover, any other possible defect, that may influence negatively the morphology of the<br />

animal, was also analyzed.<br />

INTRODUCTION<br />

Key words: morphology, morphological defects<br />

From its introduction in Italy, buffalo have had significant morphological changes, which are the result of farm management<br />

changes and selective pressure improvement. Those changes are responsible for the buffalo breed evolution. In fact,<br />

at the beginning of its introduction, buffalo were animals with three attitudes (milk, meat and draft), but through their<br />

good milk yield, along with geographical, social and economic changes in our country, buffalo expressed their productive<br />

potential, and became dairy animals. Upon to few decades ago, morphological defects were common in the buffalo<br />

species. It was because farmers did not consider important aspects of animal nutrition and wellness. Whereas, in the last<br />

few years, farmers put more attention on buffalo’s morphological selection. From 1980 to 2004, the Italian Mediterranean<br />

buffalo breed has been morphologically evaluated more as a dairy animal. At first, buffalo were evaluated by a subjective<br />

criterion that did not referred to a defined biological value. In the last few years, because of the economic importance<br />

of buffalo species, a more objective method of observation in the morphological evaluation became necessary to ensure<br />

the scientific assessment of the animal structure and, in the same time, to correct important morphological defects.<br />

Defects often cause early culling of cows (also if very good cows) from the herds. In the 2005, after a transaction period,<br />

the “linear” type evaluation has been adopted by the Italian Buffalo Breeders Association, to describe the animal by its<br />

morphological measures. This is the best method to use for scientific and selective purposes.<br />

RESULTS AND CONCLUSIONS<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Linear type evaluation of 29,051 buffalo registered in the Italian Buffalo Breeders Association Herd Book, from 2005 to<br />

2009 distributed over the years as shown in Figure 1, were analyzed. The average age of buffalo in the analysis was<br />

between 4,5 and 5,5 years. The incidence of different defects (Table 1) was evaluated.<br />

By recording in a more efficient way the morphological and structural defects of buffalo, it has been possible to calculate<br />

the frequency of individual defects. The larger frequency was for the high sacrum (code 27) and white patches (code 15)<br />

(Figure 2) defects. In conclusion, recording buffalo defects will facilitate the selection of those morphological features<br />

that ensure a better milkability (udder defects) and improve resistance against harmful factors (ex: cement, the major<br />

component of the paddock) (limbs’ defects). Finding new defects, not already coded in the linear type evaluation<br />

system, may lead to some changes to the existing table of defects.<br />

Pudding is one of the most important milk products. In this experiment an attempt was made to determine the optimum<br />

level of egg in the manufacture of buffalo milk pudding. Pudding was prepared with different levels of egg (20, 30 and<br />

40 per cent by weight) and a constant level of corn flour (4%). So, three types of pudding samples (A, B and C) were<br />

prepared. From the results of physical study, it was found that pudding containing 40% egg obtained the best score<br />

(97.50±3.77) followed by others. The differences within the overall score with different levels of egg had significant<br />

effect (p

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

buffalo milk can be a product of high value. Higher contents of fat, protein, total solids and utilizable energy per<br />

unit volume give buffalo milk a rich flavour and added value, hence utility differs from cow’s milk. Pudding is widely<br />

accepted by people in our country. If it is prepared maintaining proper hygienic conditions and compositional<br />

standards, this milk product could be an excellent supplementary food item in our diet. So, as a rich source of milk fat<br />

and protein, pudding may play a very important role to alleviate the protein-caloric malnutrition in our country.<br />

From the above discussion, it is clear that pudding is very important food item. But unfortunately there was a very<br />

limited research work performs on pudding in our country. In the aspect of Bangladesh extensive research work is<br />

essential to evaluate the feasibility of using different egg levels for manufacturing pudding. For this reason, the<br />

present research work was undertaken to manufacture acceptable quality of pudding from buffalo milk with the<br />

addition of different levels of egg.<br />

MATERIALS AND METHODS<br />

Site and duration of experiment:<br />

The present study was carried out at the Dairy Technology and Microbiology Laboratory of the Department of Dairy<br />

Science, Bangladesh Agricultural University (BAU), Mymensingh. The duration of the experiment was of one month.<br />

Collection of raw materials:<br />

Buffalo milk was collected from Senbari at Trisal Upazila under Mymensingh Distract. Chicken eggs, corn flour and sugar<br />

were collected from the Kamal Ranjit Market, BAU, Mymensingh.<br />

Chemical analysis of ingredients:<br />

Before preparation of various types of puddings whole milk, eggs and corn flour used in this study were analyzed in the<br />

laboratory to monitor the quality.<br />

The specific gravity test of buffalo milk was performed by using Quevenne lactometer, according to the method described<br />

by Aggarwala and Sharma (1961). The total solids and moisture contents of milk and different types of samples were<br />

determined by oven drying method according to Association of Official Analytical Chemists (AOAC) (2003). Fat per cent<br />

of milk was determined by Babcock method using the procedure described by Aggarwala and Sharma (1961) and fat per<br />

cent (%) of different pudding samples were determined by Ether Extraction method according to AOAC (2003). Protein<br />

was determined by Kjeldahl procedure according to AOAC (2003). Ash content of milk and pudding samples was determined<br />

by burning with muffle furnace according to AOAC (2003). Carbohydrate was determined by the calculation<br />

method. Acidity was determined by titrating with N/10 sodium hydroxide solution using the procedure of Aggarwala and<br />

Sharma (1961). pH was measured with the help of pH meter-215 (Ciba Corning Diagnostic Ltd. Sudhury, Suffolk, England<br />

Co 106 XD).<br />

Preparation of different types of pudding samples:<br />

The sugar and corn flour were mixed into the whole milk and then stirred thoroughly with the help of spoon. After proper<br />

mixing different levels of eggs (20%, 30% and 40% by weight) was added to it followed by blending. The mix was then<br />

taken in the mould and covered properly. The mould was placed in the heating pan half-full of water and kept for 1-1.5<br />

hours until the mix coagulated. The pudding was then prepared. After optimum cooling at room temperature, the mould<br />

was placed in the refrigerator for about 2 hours for cooling and the pudding was ready to serve. Here 4% corn flour is<br />

taken constant according to the study of Shamima Sultana (2007). As a result the following three samples were prepared:<br />

Sample A: 400 milliliter (ml) whole milk + 100 gram (g) egg + 20 g corn flour + 75 g sugar<br />

Sample B: 350 ml whole milk + 150 g egg + 20 g corn flour + 75 g sugar<br />

Sample C: 300 ml whole milk + 200 g egg + 20 g corn flour + 75 g sugar<br />

Proceedings 9 th World Buffalo Congress


<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Organoleptic, chemical and microbiological tests were done immediately after preparation of pudding. Total viable count<br />

and Coliform count of pudding samples were determined as per methods described in Standard Methods for the Examination<br />

of Dairy Products according to American Public Health Association (1998).<br />

Data analysis:<br />

Data obtained from different parameters were analyzed statistically designed in CRD (Completely Randomized Design)<br />

using the MSTAT statistical package programme. To find out the statistical difference between different treatments.<br />

Analysis of Variance (ANOVA) test was done. To show the relationship between mean values, the Least Significant Difference<br />

(LSD) test was done (Gomez and Gomez, 1984).<br />

RESULTS AND DISCUSSION<br />

The chemical parameters content of our experimental buffalo milk, eggs and corn flour samples were within the normal<br />

range of composition. Hence, it could be mentioned that the quality of supplied milk, eggs and corn flour samples<br />

collected were good. The physical, chemical and microbial properties of the pudding prepared in the laboratory were<br />

evaluated to monitor the quality of pudding. Pudding samples were served to a panel of judges for assessing the physical<br />

parameter i.e. physical evaluation with the help of a score card. The panel lists were selected from the teachers of the<br />

Department of Dairy Science.<br />

Abstract<br />

Many studies reported the relations among teat characteristics and milk ejection, in cow sheep and goat, but few<br />

knowlegments are reported in buffalo. Teat length, teat diameter, teat wall thickness, teat cisternal diameter and teat<br />

canal length were measured before morning milking by ultrasound at start of the trial. Milk yield and milk flow parameters<br />

were measured in 16 Italian Mediterranean Buffalo cows (parity 3.1±0.4) in mid lactation. 160 milk flow curve (udder<br />

level) were recorded in morning (80) and evening (80) milking in five different days in milk (DIM: 125, 139, 153, 166,<br />

180) utilizing a portable milkmeter Lactocorder (WMB AG Balgach). The results are presented as means±standard error of<br />

mean, using t-test to compare mean results. Statistical analysis showed that the teat length, teat diameter and teat<br />

cistern was significant higher in rear than in front quarters. The mean value of teat canal length (front and rear) was<br />

2.71±0.10 cm; it was higher those in cattle. The milk flow curve showed the predominance of increasing phase 1.89±0.18<br />

min.; decreasing phase was 1.77±0.11 min. and plateau phase was 1.55±0.12 min. The measure of teat anatomy was<br />

compared for each buffalo cow with milkability at udder level. The results showed significant Pearson correlations among<br />

teat canal length and principal milk flow parameters: maximum flow (r=-0.27; P

is not an automatic cluster detachment device. Milk ejection is influenced by anatomical 13 , physiological 13 , environmental<br />

factors and health status 4 .<br />

Buffalo species is characterized by low cisternal fraction and long teat and teat canal length, if compared to cow and<br />

small ruminant. It is very well studied 14 and known, that in dairy cow, about 20% of milk is stored in the cisternal<br />

compartment and it is immediately available for milking, in goat 6 and ewe 6 the cisternal fraction amounts to more than<br />

50%, on the contrary in buffalo species the cisternal fraction is very small, ranged between 5% - 8% of the total milk 1,13 .<br />

In Murrah buffaloes 16 has been calculated a mean teat length as 5.8-6.8 cm for front teats and 6.9-7.8 cm for behind<br />

teats. Thomas 13 reported values from 5 to 14 cm for front teats and from 8 to 16 cm for behind teats, with teat canal<br />

length about 3.1 cm in the hind than fore quarters. Buffalo species are reported to be difficult to be machine milked<br />

compared to cows. An explanation could be due to the longer teat canal, if compared to cows 14 which have been<br />

measured by an established ultrasound method 1,6,11 . In Mediterranean Italian buffalo 1 teat length is 7.45±0.44 and<br />

7.53±0.76 in hind and fore teat respectively. Therefore a large variability among different river breeds was found,<br />

according to the genetic differences and to the milking system (manual or mechanical) 13 . In this study we investigate<br />

the influence of the teat anatomy (with particular regard to teat canal length) on milkability (milk flow curve). The aim<br />

of this study was to demonstrate possible relationships between milk flow parameters and teat anatomy.<br />

MATERIALS AND METHODS<br />

Sixteen Mediterranean Italian buffalo cows, from the Tormancina Farm (Animal Production Research Centre of CRA) in<br />

Monterotondo, Italy. were used for this experiment. They were characterized by Parity 3.1±0.4, days in milk (DIM)<br />

126±17, clinical health. Each buffalo cow was recorded every one months, in morning and evening milking. Buffalo cows<br />

were milked at 08:30 AM and 19:00 PM in a Herringbone parlour (8+8), the milking vacuum was set at 42 kPa, pulsation<br />

rate was 60 cycles/min, with a pulsation ratio of 60:40. Milking clusters detachment were excluded and the stripping<br />

phase was normally performed. Milk yield and milk flow parameters were described in Lactocorder ® (WMB AG Balgach)<br />

manual instructions of this device. Oxytocin administration was useful (20 I.U. - i.m.) for each buffalo cows about two<br />

minutes of attachment milking cluster. 160 (80 morning, 80 evening) milk flow curve were recorded during the trial. Teat<br />

length, teat diameter, teat wall thickness, cisternal diameter (4.0 cm above the teat tip) and teat canal length were<br />

evaluated before first day of experiment at morning milking at start of the trial. Teat length of the front and rear quarter<br />

from each buffalo cow were measured by using a ruler. Teat diameter, teat wall thickness, cisternal diameter, and teat canal<br />

length (figure 1) were evaluated using longitudinal cross section b-mode ultrasound images (Aloka SSD-500, Aloka CO.<br />

Ltd., Tokyo, Japan). The images were recorded with a 7.5 MHz-linear probe (see figure 1). The analyzed teats were merged<br />

in a cup of hand-warm water. The ultrasound probe was closed to the outside of the cup. Between the probe an the cup<br />

was applied ultrasound gel. The statistical analysis were carried on by MedCalc ® V 9.3.0.0, results are presented as<br />

means ± standard error of mean, using t test to compare mean results (levels were considered significant when P=0.05).<br />

RESULTS AND DISCUSSION<br />

The teat anatomy measurements are shown in table 1. Teat length, cisternal diameter and the teat diameter are significantly<br />

higher in rear than in front quarters. The average length of the teats is greater than that reported by Ole Lind 16 ,<br />

which indicates the Murrah breed for front teats are, on average, 5.8 cm to 6.4 cm for the hind teats are 6.9 cm to 7.8<br />

cm. In an other study, Thomas 13 found very higher teat length (from 9.02 cm in front to 11.80 cm in rear teats).<br />

Differences in teat and cisternal diameter between front and rear teats were also significant (P

Milk yield in principal milking, maximum flow and average milk flow are negatively correlated with teat diameter and teat<br />

wall. Maximum flow, average milk flow and PP were negatively correlated to the length of the “teat canal”, while DP is<br />

negatively correlated to the “teat diameter” and positively to the “teat wall”.<br />

Unexpectedly, teat length is not significantly correlated with the main parameters of the milk flow curve, probably for the<br />

high variability. Under Oxytocin administration, alveolar milk ejection flow trough cisternal cavity finds his limits in low<br />

cisternal cavity volume itself 13 .<br />

In fact the whole alveolar milk cannot be removed, if a contemporary cisternal milk removal has not been effected. Further<br />

limitations in milk ejection finds hits limits in teat anatomy and particularly in teat canal length, which is negatively<br />

correlated with maximum and average flow at mammary level.<br />

Milkability in Mediterranean Italian buffalo species is characterized by long IP than DP and PP. Anyway we observed a<br />

long duration of DP, in contrast to bovine species, this longer time could be explained with different distribution of milk<br />

in quarters, low storage capacity of mammary cistern, and the high teat canal length.<br />

In our study that was characterized by administration of exogenous oxytocin, it was evidenced the greater influence of<br />

the teat canal length in milk ejection. This point is important because the teat canal undergoes considerable elongation,<br />

with the increasing time of milking, Thomas 13 reported increase teat elongation range between 10-13%.<br />

It is necessary to compare teat anatomy and milkability differences in all the buffalo different breeds reared in the world,<br />

because the reported results are related to Mediterranean Italian breed, which was selected during the last 50 years for<br />

the character of mechanical milkability. Finally it could be interesting to apply a heritability programme on milkability<br />

traits as that effected on Brown breed (milking speed index) 15 .<br />

Data from composition of milk from 301 buffaloes served as sample for this study, with a total of 2833 observations over<br />

a period of 18 months (May 2008 to September 2009). The animals were from a commercial herd, milked mechanically, and<br />

located in a region with harsh climate, northeast of Brazil. The objective of this study was to evaluate how the time data<br />

were collected (month, year) affected the components of milk, describing the influence of environmental factors. Concentrations<br />

of fat (F), lactose (L), protein (P), solid (S), somatic cell count (SCC) and somatic cell score (SCS) were<br />

measured. A polynomial linear regression model was use as variable for time. The variable SCS was also analyzed by means<br />

of covariance functions (VC, CS, HCS, AR (1), ARH (1)), to interpret the relationship between the different observations.<br />

The best polynomial models for the variables were: S – linear, F - quadratic, L, SCC and SCS - cubic; P - grade four. The<br />

conclusion is that variations found are consistent with expectations for the region, based on nutrition and pasture (F,<br />

L, P) and the influence of climate on the occurrence of subclinical mastitis (SCS and SCC). The covariance function with<br />

the worst shape was the VC (variance components) and the one with best shape was the HCS (heterogeneous compound<br />

symmetry), showing that there is a correlation between the different measures, and that the relationship between them<br />

tends to shrink as the time interval between the different measures grows. The influence of environmental factors on milk<br />

composition suggests the search for alternatives to minimize their impact on milk composition and health of buffaloes,<br />

with particular attention to the rainy season when there is an increase on the content of somatic cells.<br />

INTRODUCTION<br />

Key words: heterogeneous compound symmetry, milk composition, SCC, SCS<br />

Buffaloes have the potential for high milk production, hardiness, resistance to ectoparasites, lower frequency of mastitis,<br />

may be raised in areas which are unsuitable for cattle and require a lower cost of production 1 . According to IBGE 2 , the<br />

Northern Region holds the largest national herd with 541,674 animals (64.49%), followed by the South (12.79%),<br />

Southeast (9.12%), Northeast (9.09%, with 76,348 head) and Midwest (4.51%). There are many factors that can interfere<br />

with milk constituents and their quality, such as feeding, handling, environmental factors, climate, genetics 3,4 . The<br />

objective of this study was to evaluate how the time data were collected (month and year) affected the components of<br />

milk, describing the influence of environmental factors.<br />

Abstract<br />

Buffalo economic exploitation for milk production is a new fact in the southernmost Brazilian region. The production<br />

chain structuring of this activity was started in the year 2000, and nowadays dairy products, identified and labeled as<br />

such, are available in the consumer market. However, the present-day dairy products output corresponds to only 50% of<br />

market demand. The aim of this paper is to evaluate buffalo milk produced in Rio Grande do Sul state both qualitatively<br />

and quantitatively as a subsidy for the adoption of a breeding program and the development or adaptation of technologies<br />

so that this cattle-raising activity has a greater financial appeal. Two properties are currently under evaluation,<br />

each of them holding approximately 70 lactating females from Murrah and Mediterranean breeds. The feeding system used<br />

is pasture, with supplement in wintertime. Total milk production of each female is measured every 28 days, and individual<br />

milk samples are collected for chemical analysis and somatic cell count (SCC). Data collection started in February 2009, as<br />

far as October 2009, 900 samples had already been collected. The mean milk production per animal was 7,01±1,13 kg for<br />

the Murrah breed and 3,24±0,61 kg for the Mediterranean. Quality traits were 4,45±0,24 and 3,73±0,41% (fat); 3,83±0,26<br />

and 3,82±0,49% (proteins); 5,04±0,08 and 5,20±0,16% (lactose); 14,47±0,46 and 13,85±0,81% (total solids) and SCC<br />

mean value was 112,765±75,269 and 50,222±24,952 cell/ml for the Murrah and Mediterranean breeds, respectively.<br />

These quantity and quality differences can be attributed to the feeding system, management and individual variations,<br />

in addition to animal breed. Preliminary data have shown that a genetic improvement program and the development or<br />

adaptation of technologies from different areas of knowledge is vital to obtain higher productivity so that this can be<br />

a viable activity in this region.<br />

Key words: chemical composition; quality; production systems.<br />

INTRODUCTION<br />

The economic exploration of buffaloes is a quite recent activity in Southern Brazil. From the year 2000 onwards, with the<br />

establishment of “Cooperbúfalo” (Sulriograndense Cooperative of Buffalo Raisers), the structure of the productive chain<br />

was started in this area; nowadays, dairy products, mainly cheese – identified and valued as<br />

such – are available in the market.<br />

Buffalo milk present an important role in providing high quality dairy products, especially mozzarella cheese, which is<br />

sells for a price up to four times as high as that of its bovine counterpart at present. The buffalo milk is more concentrated,<br />

and has a higher fat, protein and mineral content, exceeding bovine milk yield in over 40 % 9 .<br />

The aim of this study is to evaluate the production and quality of milk from buffaloes raised in Rio Grande do Sul State<br />

as a subsidy towards the introduction of a genetic improvement program, as well as the development and/or adaptation<br />

of technologies which can turn it into a more attractive ranching activity.<br />

Proceedings 9 th World Buffalo Congress


MATERIAL AND METHODS<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Two farms located in Eastern Rio Grande do Sul are evaluated, each holding approximately 70 lactating female buffaloes;<br />

farm 1 raising Mediterranean breed animals and farm 2, Murrah breed ones. The feeding system in use is pasture with food<br />

supplementation. On farm 1, the animals graze native pasture through a rational rotational grazing system, which<br />

includes a winter supplementation of chopped grass elephant (Cameron variety) and cassava in the trough. On farm 2, the<br />

animals are given sorghum silage in full year, and both winter (oat plus Italian rye grass) and summer (Tifton 85 grass plus<br />

millet) cultivated pasture.<br />

The collection of data began in February 2009 being collected over 900 samples until October 2009. The milking is<br />

mechanized, and daily individual production is measured every 28 days. Individual milk samples are also collected for<br />

chemical composition analysis (fat, protein, lactose and total solids) by means of an infrared ray absorption reading in<br />

a Bentley 2000® analyzer, and the somatic cell count is performed by flow cytometry in the Somacount 300® equipment<br />

at the milk quality analysis laboratory of Embrapa Clima Temperado (Embrapa Temperate Climate Center). The data are<br />

checked by variance analysis (ANOVA) and the mean differences calculated by the Tukey test at a 5% probability rate<br />

through the STATISTIX 8.0 software10 .<br />

RESULTS AND DISCUSSION<br />

The mean daily milk production per animal, its chemical composition, and the somatic cell count are expressed on a<br />

monthly basis for each farm in Table 1. The data are descriptive, thus not corrected as to age effect, stage or lactating<br />

days.<br />

Table 1: Mean milk production per animal (Production), chemical composition (Chemical comp.), and somatic cell<br />

count (SSC) per farm per month.<br />

Means in small letters on the lines: differences among the months of the year for each farm; means in capital letters on the<br />

columns: differences between the two farms<br />

Generally speaking, the results obtained show a downward tendency by the end of autumn and in winter. This value fall<br />

can be attributed to a decrease in forage availability.<br />

As to chemical composition, the mean data obtained are lower than those found in other areas of the country. In the<br />

state of Pernambuco, chemical characteristics mean percentages were: 6,99 % (fat); 4,01 % (protein); 4,72 % (lactose);<br />

16,85 % (total solids), and an SCC mean value of 269,590 cells/ml. The mean daily milk production was 4,78 kg/day per<br />

animal 7 .<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Similar results were obtained in the state of São Paulo. The fat, protein, lactose and total solids mean percentages were<br />

6,83 % and 6,59 %; 4,20 % and 4,13 %; 5,02 %; 17,23 % and 17,01 %, respectively 3,8 . The somatic cell count mean value<br />

was 137,000 cells/ml for Murrah and Mediterranean breed female buffaloes 3 . The mean milk production was 4,52 kg/day<br />

for Mediterranean breed animals 8 .<br />

Similar data those obtained in this study were also found In Rio Grande do Sul. The mean daily milk production was 4,0<br />

kg for Murrah buffaloes in their first lactating period. Fat and total solids mean percentages were 5,48 % and 14,24 %,<br />

respectively. The animals were kept on natural pasture with grazing in cultivated pasture of the winter (oat and rye grass)<br />

for two hours every day 4 . Another piece of research reports an even lower mean fat percentage (4,56 %) 6 .<br />

Milk components (fat, protein, lactose and total solids) can vary according to nutrition, season the year, as well as animal<br />

effect, such as age, breed and lactating stage 1 .<br />

The somatic cell count over 200,000 cells/ml can be an indicator of mastitis where values lower than 100,000 cells/ml<br />

may mean healthy mammary quarters5 . The mean values obtained from farm 1 (43,000 cells/ml) are within those for<br />

healthy animals (without mastitis); on farm 2, however, there were periods (July and September) when the animals<br />

presented mastitis problems (the mean count over 200,000 cells/ml).<br />

The low somatic cell count for female buffaloes can be attributed to a higher resistance of the species to mastitis. This<br />

resistance can be related to anatomic features of the udder and teats, mammary gland immunology and milk composition2<br />

.<br />

CONCLUSIONS<br />

The difference in milk production and quality can be attributed, in addition to breed, to the feeding system,<br />

management and individual variations.<br />

The preliminary data evidence that a genetic improvement program together with the development and/or adaptation of<br />

technologies in different areas of knowledge are indispensable in order to reach a level of productivity that can make this<br />

activity viable in this region.<br />

Abstract<br />

Mastitis is a chronic disease and can affect the various species of cattle, including buffaloes, causing great damage to<br />

the milk production chain. In a way to control mastitis, the somatic cell count (SCC) has been used as a tool for<br />

management of the dairy herd. This study evaluated the presence of somatic cells in Murrah buffaloes in northeastern<br />

Brazil, between May/2008 and October/2009. We used information from 3186 SCC. In absence of linearity with the<br />

production of milk, the SCC was transformed into somatic cell score (SCS), with [log2 (SCC/100) + 3]. The data were<br />

analyzed by SAS (2008) and the correlations of SCC and SCS with the composition of milk were considered. The means and<br />

standard deviations of SCC and SCSx10 3 were 584.6 ± 1266.4 x10 3 and 2.57 ± 1.07, respectively. More than half of<br />

production (56.88%) had values of SCC below 200x10 3 . The correlations of SCC and SCS with the characteristics of the<br />

composition of milk were all significant, with the exception of SCC and solids. Lactose showed negative associations with<br />

SCC (- 0.44) and SCS (- 0.49), which is extremely undesirable, since this component is of great importance for the dairy<br />

industry. The results of SCC suggest the need to implement a control program to reduce sub-clinical mastitis in the herd.<br />

INTRODUCTION<br />

Key words: mastitis, Murrah, Northeast Brazil, somatic cell count, somatic cell score.<br />

Mastitis is a chronic disease and can affect all mammals including buffalo, causing losses for the entire production chain,<br />

particularly in the production of cheese. This inflammation of the mammary gland can be characterized by increased<br />

number of somatic cells (SCC) in milk. The SCC is used as a tool for control of udder health, intended to the management<br />

and selection in herds 10 . In fact, the SCC has been used for diagnosis of mastitis in bubalinos 7,9,11 and it seems likely that<br />

more than 200,000 cells/mL is indicative of infection of the udder. The European Union Directives (92/46CEE and 94/<br />

71CEE) set a limit of 400,000 cells/mL for SCC in raw buffalo milk, when milk is used for products made with raw milk.<br />

Clinical and sub-clinical mastitis cases in Brazil are in the order of 1.5 and 18.77% respectively. The main goal of this<br />

study was to evaluate the presence of somatic cells in cattle buffaloes in the Brazilian Northeast and estimate correlations<br />

between this characteristic and the chemical composition of milk.<br />

Buenos Aires, Abril 2010 585


MATERIAL AND METHODS<br />

586<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Data for SCC were obtained from lactations of Murrah buffaloes in a total of 3,186 observations from May/2008 to October/<br />

2009, a commercial herd milked mechanically twice a day without calf at foot, fed mainly of Brachiaria brizantha and Stylosanthes,<br />

created in the region of tropical climate in the Northeast of Brazil. Milk samples were collected in the morning and sent to<br />

the laboratory for milk quality, in sterile plastic bottles with a capacity of 60mL, containing one tablet of preservative (azidiol).<br />

SCC was determined by flow cytometry (Bentley 2000 ®). The data were statistically analyzed by GLM and CORR 11 programs, and<br />

the means compared by SNK test. The SCC was transformed into somatic cell score (SCS), with [log2 (SCC/100) + 3] 15 .<br />

RESULTS AND DISCUSSION<br />

The means and medians of SCC and SCS were 1266.4 ± 584.6x10 3 and 2.57 ± 1.07 and 152.5 and 2.18, respectively. The<br />

mean SCC was higher than those found in other studies in Brazil 2,5,8 , Pakistan 1,13 and Italy 14 .<br />

Table 2 shows the relative and accumulate frequencies on the SCC, depending on the ranges of cell counts observed. It is<br />

important to note that over 50% of the observed data are up to 200x10 3 , from which is indicative of infection in the<br />

udder of búfalas 7, 9,11 .<br />

Table 2. Relative and accumulate frequencies on the SCC, according to the range considered<br />

Estimates of SCC and SCS correlation with constituents of the composition of milk were all significant. The most notable<br />

are the negative associations between SCC and SCS with lactose (- 0.44 and - 0.49, respectively), which agrees with other<br />

authors 4, 13 . The variable month/year significantly affected (P < 0.01) SCC and SCS. The months of the year 2008<br />

provided lower values of SCC and SCS. Presumably, the fact that the buffaloes are older in 2009 may have contributed<br />

to the increase of somatic cells in the herd. The SCC results suggest the need to implement a control program to reduce<br />

sub-clinical mastitis in the herd.<br />

This study aimed to investigate the relationship between somatic cell count (SCC) in milk and intramammary infection<br />

(IMI) in Egyptian buffaloes as well as to assess SCC threshold values for detection of subclinical mastitis. A total number<br />

of 339 quarter milk samples were collected from 113 milking buffaloes raised in Mehalet Mousa experimental farm belonging<br />

to Animal Production Research Institute, Agriculture Research Center, Egypt. Milk samples were taken (aseptically<br />

from each quarter) in separate sterile tubes for bacteriological analysis and determination of (SCC) using the fluoro-optoelectronic<br />

method. Average of log SCC in milk samples from non infected and infected quarters were 4.82±0.09 (66 x 103<br />

cells/ml) and 4.98±0.08 (96 x103 cells/ml), respectively. Log SCC in milk was significantly (P

quarters. Thus, reducing mastitis incidence is important for economical and animal welfare attitudes. This attempt can<br />

lead to greater flexibility in breeding programs.<br />

Mastitis screening tests such as SCC, conductivity test and determination of lactose in milk became essential for monitoring<br />

herd level of udder health programs. In addition, adoption of pre-calving udder hygiene, disinfectant teat<br />

dipping, dry off therapy are important procedures to prevent IMI. There is lack of information on SCC threshold between<br />

healthy and infected udders of Egyptian buffaloes to be used as hazard against IMI. Determination of various SCC<br />

thresholds depends on bacteriological culture as the standard method for identifying IMI. Therefore, this study aimed to<br />

investigate the relationship between SCC in milk and IMI in buffaloes as well as to assess SCC threshold values for<br />

detection of subclinical mastitis.<br />

MATERIAL AND METHODS<br />

A total of 339 quarter milk samples were collected from 113 milking buffaloes raised in Mehalet Mousa experimental farm<br />

belonging to the Agriculture Research Center, Egypt. Milk samples were collected throughout experimental period which<br />

lasted one year. In order to identify the effect of season of milking on SCC, the collected data were divided into two<br />

climatic periods i.e the 1st sampling period (Hot climatic period) from April to September while, the 2nd period (Cold<br />

climatic period) was from October to March. In order to avoid the effect of stage of lactation on SCC, milk samples were<br />

collected during the mid-lactation period (60 to 135 days) for each animal. The udder of each buffalo was inspected to<br />

detect incidence of mastitis, buffaloes defined as clinically infected were excluded from the study. Number of milk<br />

samples collected from machine milking and hand milking buffaloes were 114 and 225, respectively.<br />

Diagnostic criteria:<br />

In the present study, Staph. aureus, Str. agalactiae , Str. uberis , Str. dysgalactiae and Coliform spp. were defined as major<br />

pathogens whereas, Coagulase Negative Staphylococci (CNS), and Corynbcateria spp. were defined as minor pathogens.<br />

According to Moroni et al. (2006), IMI was defined by either of : 1) Isolation of one colony (?100 cfu/ml) at least of<br />

major pathogens, 2) Isolation of ?500 cfu/ml of other microorganisms and 1-3 colony types. Milk samples from which ><br />

3 colony types or < 500 cfu/ml microorganisms were regarded as contaminated or uninfected, respectively. Accordingly,<br />

the udder status (IMI) was categorized as 1-Non infected, 2-infected by a single major pathogen, 3- infected by a single<br />

minor pathogen, 4- infected by one major pathogen plus one minor pathogen, 5- infected by one major pathogen plus<br />

two minor pathogens and 6- infected by two major pathogens plus one minor pathogen.<br />

Farm management:<br />

Milking buffaloes were kept restrained under sheds from the morning (7.00 a.m.) till the evening (4.00 p.m.) thereafter<br />

they were kept loose in the shed during the rest of the day. Part of the experimental buffaloes were milked by hand (HM)<br />

where others were milked by machine (MM) twice daily at 7.00 a.m. and 4.00 p.m. throughout the lactation period.<br />

Milk sampling and analysis:<br />

Prior to milking, the udder and teat ends were scrubbed with 70% ethanol. About 15 ml of fore milk and 15 ml of<br />

stripping was taken aseptically from each quarter into separate sterile tubes for bacteriological analysis. All samples were<br />

kept on ice box (6ºC) and transported to the laboratory until analysis. Somatic cell counts were determined by the fluoroopto-electronic<br />

method using Fossomatic 5000; Foss Electric apparatus, 3400 Hillerod, (Denmark). Counting of SCC was<br />

adopted within 24 h. postcollection following the rules of the International Dairy Federation (1984). Original scale SCC<br />

values were transformed to log arithmetic according to Ali and Shook (1980) to achieve an approximate normal distribution<br />

of hypothesis testing. Evaluation of SCC and bacteriological examination were conducted according to National<br />

Mastitis Council standards (NMC, 1999).<br />

Bacteriological examination:<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Milk bacteriological examination was performed using all quarter milk samples. Detection and enumeration of mastitis<br />

organisms were performed by serial dilutions of milk samples, isolation and enumeration of pathogens were according to<br />

standard method (APHA, 1993). The presumptive coliform bacterial count was counted using Macconkey agar media. The<br />

presumptive Streptococcci groups causing mastitis (Str. agalactiae, Str. dysgalactiae ,Str. uberis) were enumerated on<br />

modified Edward’s media and blood was added to the media for identification of blood hemolytic bacteria. The presumptive<br />

Staphylococcus aureus (Staph. aureus) and CNS were counted on Baird Parker agar media with sheep blood for<br />

appearance of hymolysis. Blood agar (Nutrient agar media plus sheep’s blood) was used for enumeration Bacillus spp.<br />

Blood agar (Nutrient agar media plus sheep’s blood) with potassium tellurite was used for presumptive Corynebacterium<br />

species. All plates were incubated at 37ºC and examined after 24 hours, then again at 48 hours; these selective and<br />

differential media were obtained from Oxiod (Hampshire, England).<br />

Statistical analysis:<br />

Statistical analysis was carried out using the MIXED procedure of SAS (1998) Data were analyzed using the following<br />

model:<br />

Y ijklmno = ? + SII + Pj + SI*Pij + A (SI*P)ijk + Sl + MTm + Qn + e ijklmno<br />

where Yij is the dependent variable (log10 SCC), ? is the overall mean, SII is the effect of status of infection (6<br />

categories of defined IMI), P is the effect of animal`s parity (the 1st – the 6th parity) , SI*P is the interaction between<br />

status of infection and animal `s parity, S is the effect of season of milking (hot season vs. cold season), MT is the effect<br />

of milking type (HM vs. MM), Q is the quarter site effect (4 levels) and eijklmno is the random error.<br />

Thresholds of SCC:<br />

To determine the validity of SCC for identifying infected quarters, sensitivity and specificity were determined at selected<br />

thresholds. Sensitivity was calculated as the proportion of culture-positive quarters that had SCC values above the<br />

selected threshold, and specificity was the proportion of culture-negative quarters that had SCC values below the selected<br />

threshold (Martin et al. 1987). The threshold values used for validating SCC were 50, 100, 150, 200, 250 and 300 x<br />

103 cells/ml.<br />

RESULTS AND DISCUSSION<br />

Factor affecting somatic cell count (SCC) in milk:<br />

Data of the present study indicated that average of log SCC in milk samples from non infected and infected quarters were<br />

4.82±0.09 (66 x 103 cells/ml) and 4.98±0.08 (96 x103 cells/ml), respectively. These estimates are relatively coincident<br />

with that obtained by Ceron-Munoz et al. (2002) on Brazilian buffaloes while, it is lower than that obtained by Singh and<br />

Ludri (2001) on the Indian buffaloes and EL-Bramony (2004), Saleh (2005) and Youssef et al. (2008) working on<br />

Egyptian buffaloes. As reported by Dhakal (2004), SCC in normal buffalo milk in Srilanka varied from 50,000 to 375,000/<br />

ml<br />

Proceedings 9th Least square means of log SCC in milk samples collected during hot and cold seasons were 4.63± 0.07 and 4.76± 0.07,<br />

respectively. Least square means of log SCC in milk samples obtained from right front, left front, right rear and left rear<br />

quarters were 4.68± 0.07, 4.68± 0.07, 4.70 ± 0.07 and 4.71±0.07, respectively. This finding indicates that log SCC was<br />

slightly higher in the hind quarters than that in the front ones. Schepers et al., (1997) indicated a higher prevalence of<br />

IMI in the rear quarter of cattle accompanied with higher rate of false negative samples and higher SCC as compared with<br />

that of the front quarters. Saleh, (2005) found that teat position had insignificant effect on SCC in milk of buffaloes.<br />

Zadoks et al. (2001) detected a significant higher rate of Staph. aureus in the rear quarters than in front quarters of<br />

cows. In contrary, Dhakal (2004) found that average SCC in buffalo milk of right front and right rear quarters were<br />

significantly higher than left front and left rear quarters.<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Data shown in Table (2) indicate that quarter milk samples with IMI represented 62.24% of samples whereas, 37.76% of<br />

samples were non infected. In agreement, Moroni et al (2006) found that in two Italian farms, prevalence of IMI was 63%<br />

of infected quarters. However, Dhakal (2004) stated that prevalence of subclinical mastitis was found in 21.7 % of<br />

buffaloes and 8 % of the quarter foremilk samples. The Author diagnosed subclinical mastitis on the bases of samples with<br />

SCC 200,000 cells/ml with positive cultures. Greater percentages of samples with IMI in our study had a single major<br />

pathogen in both types of milking in comparison with other categories of IMI. The proportion of samples taken from MM<br />

buffaloes with IMI (21.74% non infected vs. 78.26% infected) is nearly double those taken from HM buffaloes (45.98%<br />

non infected vs. 54.02% infected). This result may be referring to the greater percentages of one major pathogen plus<br />

two minor pathogens (11.3%) and two major pathogens plus one minor pathogen (11.91%) in MM samples. Zadoks et al.<br />

(2001) indicated that poor milking machine function could lead to teat-end callosity and to increased risk of Staph.<br />

aureus IMI.<br />

As shown in Table (3), average log SCC in milk samples from non infected quarters was 4.63±0.08 (43 x103 cells/ml). This<br />

finding is comparable with that obtained by Youssef et al. (2008) who found that average log SCC in buffalo milk samples<br />

were 4.87 and 5.66 in non infected and subclinically infected quarters, respectively. Average of log SCC in milk samples<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

from quarters infected with major pathogens (4.75±0.09) was relatively greater than that of quarters infected with minor<br />

pathogens (4.59±0.07). The highest log SCC in samples with IMI was observed in samples containing a single major<br />

pathogen (4.83 ±0.08) or those containing two major plus one minor pathogen (4.89 ±0.12). Samples that contained a<br />

single minor pathogen had the least log SCC (4.52±0.09). Milk samples from MM buffaloes had relatively greater log SCC<br />

than samples obtained from HM animals, except for the samples infected by one major plus one or two minor pathogens.<br />

Schepers et al. (1997) concluded that the increase in SCC was more pronounced for major pathogens than for minor<br />

pathogens so that in herds with greater prevalence of major pathogens, higher thresholds would be expected. Zadoks et<br />

al. (2001) concluded that low SCC quarter was not associated with increased rate of IMI with Strep. uberis or Staph.<br />

aureus in cattle.<br />

As shown in Figure (2), log SCC in milk samples of non-infected quarters followed a clear pattern among the subsequent<br />

lactation periods as log SCC had the minimum count (4.42) at the 1st parity then increased gradually until the 3rd parity<br />

(4.66) and stabilized between 4.67- 4.70 thereafter. The infected quarters showed a fluctuated trend of log SCC characterized<br />

by the highest count (4.92) in the 2nd parity then abruptly declined to reach a minimum count (4.48) at the 3rd<br />

parity. The sharp increase in log SCC in infected samples of the 2nd parity is virtually related to greater log SCC in samples<br />

infected with one major plus two minor pathogens (5.08±0.23) or two major plus one minor pathogen (5.14±0.2).<br />

Zadoks et al. (2001) concluded that the rate of infection with Strep. uberis and Staph. aureus was lower in the 1st and<br />

2nd parity cows than in older cows.<br />

SCC threshold:<br />

594<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

A threshold of 50,000 cells /ml of milk of buffaloes was shown to have a high sensitivity and specificity for identifying<br />

IMI (Table 4). Sensitivity% was inversely related with the assigned thresholds of SCC, this finding is in agreement with<br />

Sargeant et al. (2001) who observed that within each of IMI categories, the sensitivity of SCC for identifying infected<br />

quarters decreased and the specificity increased as the SCC threshold increased. The term, correctly classified samples<br />

denotes proportion of true positive plus true negative samples e.g. the greater the proportion of truly inspected samples,<br />

the more accurate threshold level for identifying IMI. In this context, Schepers et al (1997) indicated that as the<br />

prevalence of IMI in cows increases with parity and stage of lactation the number of false negative samples also increases.<br />

Meanwhile, Moroni et al (2006) concluded that 98 % of quarters in buffaloes with SCC below the threshold 200,000 cells/<br />

ml were uninfected.<br />

Table (4) Percentages of true and false classification and sensitivity with specificity in different SCC thresholds levels for<br />

Egyptian buffaloes.<br />

CONCLUSION<br />

The present study revealed that the infection status and parity of the animal were the most important factors affecting<br />

SCC in milk of buffaloes. Therefore, a considerable percent (62.24%) of IMI was noticed in the study. Moreover, inefficient<br />

use of machine milking may provoke opportunity of IMI and increased SCC in milk. Although, the mammary gland<br />

in buffaloes are characterized by thick keratinized streak canal barrier and strong teat sphincter, effectiveness of those<br />

features may be reduced with advancing age thus allowing increased entry of pathogens. The major pathogens Staph.<br />

aureus and Strep. disagalactea were predominant in the present study whereas, Corynbacteria spp represented a predominant<br />

minor pathogens.<br />

It was also observed that the increase in SCC was more pronounced for major pathogens than for minor pathogens.<br />

Furthermore, presence of one or more major pathogens was a predisposing factor for SCC elevation in milk of buffaloes.<br />

A threshold of 50,000 cells /ml of milk of buffaloes was shown to have a high sensitivity and specificity for identifying<br />

IMI. Such threshold may be lower than that recorded on buffaloes in other studies. Further studies on large scale of<br />

sampling is recommended to identify various SCC thresholds in milk of buffaloes taking into account specificity in the<br />

different herds and different stages of milking.<br />

Abstract<br />

This work was carried out to evaluate the sensory characteristics of dairy beverages prepared from buffalo milk and<br />

different levels of yogurt and whey, resulting the five treatments: T1 - 10% milk plus 10% whey and 80% yogurt; T2 - 10%<br />

milk plus 20% whey and 70% yogurt; T3 - 10% milk plus 30% whey and 60% yogurt; T4 - 10% milk plus 40% whey and<br />

50% yoghurt; T5 - 10% milk plus 50% whey and 40% yoghurt. Sensorial acceptance test was performed, for hedonic scale<br />

of 5 points, and order of preference of all treatments. The formulations with 10% and 20% whey were the most accepted<br />

in sensory acceptance and preference tests by the testers.<br />

INTRODUCTION<br />

Key words: quality, dairy beverages, whey<br />

Dairy beverages are a result from the mixture of milk (in natura, pasteurized, esterilized, UHT, reconstituted, concentrated,<br />

powder milk, whole, semi-skimmed and skimmed) and milk whey (liquid, concentrated or powder), added or not with<br />

food product(s) or food substances, which the dairy portion represents at least 51% mass/mass (m/m) of the total. For<br />

dairy factories, the conversion of milk whey into dairy beverage is the most appealing option for human consumption,<br />

due to the easiness of the process. Moreover, the problems of waste products are reduced. Whey products not only permit<br />

the producer to reduce the total amount of ingredients, but also present exceptional functional properties. Furthermore,<br />

they are a source of dairy nutrients, especially high nutritional value proteins and calcium. The objective of this study<br />

was to evaluate sensorial characteristics of dairy beverages elaborated from buffalo milk and different levels of yogurt and<br />

dairy whey.<br />

MATERIALS AND METHODS<br />

The milk was acquired from Murrah buffalo and 5 processings were conducted, at each 10th day, constituting repetitions.<br />

Whey was obtained by Tipo Frescal cheese processing under treatment of 85?C/30 minutes and pasteurized milk under<br />

the processing of 62-65?C/30 minutes. Yogurt was elaborated from whole milk, 12% sugar, 2,5% dairy concentration and<br />

5% strawberry pulp. Yogurt was mixed with whey and milk, and 5 treatments were obtained: T1 = 10% milk, 10% whey and<br />

80% yogurt; T2 = 10% milk, 20% whey and 70% yogurt; T3 = 10% milk, 30% whey e 60% yogurt; T4 = 10% milk, 40%<br />

whey and 50% yogurt; T5 = 10% milk, 50% whey e 40% yogurt. Acceptability test was conducted by a group of 200 non-<br />

trained testers, from which 40 testers were designated to each processing repetition, following an hedonic scale of 5<br />

points, divided into: global impression, appearance, consistency and flavor. For the Order of Preference test, 100 testers<br />

were selected as a function of the maximum number of answers which could be evaluated by the method, with 20 testers<br />

to each repetition, in which each tester indicated his/her preference. The data was evaluated by the minimum significant<br />

difference of the sum of orders by Friedman Method (3). The tests were simultaneously applies, at the Laboratory of<br />

Sensorial Analysis/UESB, in individual cabins. Samples were served in disposable glasses of 50 mL, codified with 3 digit<br />

numbers, together with a 200 mL water glass for tasting breaks. The grades were submitted to ANOVA using Random<br />

blocks Design and Turkey Test, at 5% probability (4).<br />

RESULTS AND RESULTS<br />

Overall, samples presented significant differences (Table 1) in terms of evaluated attributes (p0,05) in none of the attributes. Therefore, in terms of acceptance, there was not a<br />

difference among levels from 10 to 20% of whey, with average values equivalent to “like” in the hedonic scale.<br />

Table 1- Average values from Acceptance Test for global impression, appearance, consistency and flavor of dairy beverages<br />

elaborated from buffalo milk.<br />

Averages followed by different letters in the same line are statistically different by t test at 5% probability<br />

he highest values for consistency in T1 and T2 may be attributed to the fact that these treatments presented a yogurt<br />

consistency, a character commented on their profile. In terms of global impression, T3 and T4 were similar (p>0,05).<br />

Although, they presented lower average values for all attributes once compared to T1 and T2. This result may be due to<br />

the level of whey, a substance that gives dairy beverages a non-homogenous aspect. T5 had the lowest averages for all<br />

attributes, statistically differing from the rest. According to Friedman Method, Random block Design for obtaining a<br />

significant difference among treatments at 5% was 61. Therefore, only T1 and T2 did not significantly differ among<br />

themselves (p>0,05), with difference modules of 25, and considered the best for testers. All the combinations left<br />

presented significant differences, of values ranging from 65 to 286 for Random block Design. These results agree with the<br />

ones from Acceptance test, which demonstrated no difference between T1 and T2.<br />

INTRODUCTION<br />

Keywords: buffaloes, mechanical milking, behavior, milk production, animal welfare.<br />

Studies of milking behavior assist technicians and breeders by providing suitable information concerning the development<br />

of systems committed to animal welfare and productivity1. Among cows, order of entry into the milking parlor and<br />

choice of milking side2 tend to be consistent, and those variable may or not2 affect milk production when the animals<br />

are milked from the non-preferred side, and the animals may even present changes in their social behavior or in the<br />

parameters that are indicative of their welfare3.<br />

Milk production has been found to correlate positively with the hierarchy rank, live weight and age, among cows and<br />

buffaloes4,5; however, little is known about the behavioral differences among female buffaloes during milking.<br />

This study aimed to verify whether Murrah buffaloes prefer a milking side and whether any behavioral difference is present<br />

across animal categories and production levels.<br />

MATERIAL AND METHODS<br />

The studied population comprised 248 animals in Recôncavo of Bahia, Brazil (12º30’50.00’’S and 38º29’42.64’’W), which<br />

participate in the genetic program with monthly Milk Control. On five consecutive days, records were made of: entrance<br />

order, individual side choice (left or right), observer, milk production (kg), date of birth and parturition. The analyzed<br />

variables were: side preference (PREF), 1 for left, 2 for right and 3 for neither side, and percent side change (COEF, 0 to<br />

50%) as a result of the number of changes per number of observations for each animal. Category 1 comprised the first or<br />

second-parturition buffaloes and category 2 all the others. Lower level meant production below the overall mean (equal<br />

to 5.4kg), whereas production above that mean was rated as higher level. The analyses were completed with the Statistical<br />

Analysis System (SAS, 2002) and Excel for Windows.<br />

RESULTS AND DISCUSSION<br />

Out of 950 observations in total for the choice of milking side in the parlor, females preferred the left side 54.3% of<br />

times. Following the Chi-square Test using alpha=0.05, it was found that the buffaloes preferred the left side (P


ight side).<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Production levels were statistically different (P0.05) between younger and older adults concerning PREF was found following the Chi-square<br />

Test for alpha=0.05 and three degrees of freedom. There was a clear linear tendency (R2=0.41) for adult animals to<br />

present low COEF, as shown in Figure 1.<br />

To study the differential leukocyte counts (DLC) in the colostrum of Murrah buffalo, colostrum was collected from 30<br />

healthy Murrah buffaloes after calving continuously upto 5 days. Colostrum was collected aseptically in cleaned milk<br />

bottles from each animal in each day to see the day to day variation in somatic cell counts (SCC) and DLC in the<br />

colostrum. It was found that the SCC were significantly higher (P


<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Successively dyed with Leishman stain solution for 20 min, rinsed with water and then again air dried. SCC of colostrum<br />

samples were measured microscopically. DLC was also carried out to determine the presence of different cell types like<br />

lymphocytes, neutrophils and macrophages in colostrum. The SCC and DLC were measured under the microscope with a<br />

magnification of 100 X 10. For SCC and DLC the slides were prepared within one hour of collection of milk samples. Milk<br />

SCC was estimated microscopically3. The SCC were measured under the microscope with a magnification of 100 X 10 in<br />

200 fields and average number of cells per field was multiplied by the microscopic factor (8.81134633). The microscopic<br />

factor was determined by using ocular and stage micrometer. Somatic cell counts/ml of milk (lakh) = Average cells count<br />

in one field x 8.81134633. The DLC is estimated in percentages. The data obtained were subjected to statistical analysis<br />

using least square analysis of variance.<br />

RESULTS AND DISCUSSION<br />

Mean ± SE values of SCC (105 cells /ml) and DLC during different days of colostrum in Murrah Buffaloes have been<br />

presented in Table no. 1. Colostrum SCC were significantly higher (P

This study was carried in the village of Fudhaliyah / Baghdad governorate during winter and summer / 2007, to study the<br />

effect of herd size and age at first birth, number of days open and the chapter on the daily milk production of a sample<br />

of Iraqi buffaloes.<br />

The study included 200 educators from their property between 4-250 head of the buffalo of different ages were selected<br />

at random. Has registered each of the total herd size and milking herd size and age at first birth, in addition to the daily<br />

production of milk during the winter and summer. Has been divided by the total herd and dairy herd to 6 groups<br />

according to the size of property. Daily milk production was significantly higher (0.01p

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

With a focus on the impact of environmental factors, especially nutrition, in the productivity of milk and animal fat<br />

under those circumstances controlled (9, 21, 25). But not to other factors and physiological management of no less<br />

importance in their impact on production, such as herd size, age at first birth, number of days open, and other production<br />

season, particularly in the production conditions prevailing in Iraq. The system of breeding Extensive or free grazing<br />

l and herd size disparity between the number of animals to several hundreds of them, , scarcity of fodder, and other<br />

factors that lead to a significant disparity in the productivity of animal milk and meat.<br />

Based on this study was conducted to shed light on the reality of the daily production of buffalo milk in Iraqi and the<br />

factors influencing it in terms of herd size, age at first birth, number of days open as well as the production season, based<br />

on data collected for a period of one year to sample a relatively large area Fudhaliyah in Baghdad province.<br />

Materials and methods<br />

This study was carried in a questionnaire Random Survey of a sample of buffalo breeders numbered 200 in the village of<br />

Fudhaliyah located at eastern border of Baghdad ,as the number of buffalo which about 20000 header (2).<br />

Questionnaire has been some important elements in the process of raising buffalo, such as: the total herd size, the size<br />

of herd milk, female age at first birth, number of days open Days open (which is the period between delivery status and<br />

another conception ) as well as the amount of milk daily in summer and winter seasons. As the questionnaire on the type<br />

and quantity covered in animal feed, which was similar to a large extent between buffalo farmers, which included: alpha<br />

alpha (10 kg) or bran (4 kg) per animal per day, in addition to the straw (wheat or barley straw) or Alboh (rice straw) as<br />

requested by the animal and the financial ability of the breeder.<br />

Breeders have been classified on the basis of ownership to 6 groups: 1 (4-10), 2 (11-20), 3 (21-30), 4 (31-40), 5 (41-<br />

50) and 6 (more than 50 head). Herd has been classified by the number of animals, milk cows in the herd one at random,<br />

regardless of the age of the animal, to groups would be:<br />

Group I (1) The herd, which consists of 1 to 10 individuals.<br />

Group II (2), from 11 to 20.<br />

Group III (3), from 21 to 30.<br />

Group D (4) from 31 to 40.<br />

Group V (5) 41 and more.<br />

Has been classified into two seasons of production seasons are summer and winter, and adopted the dairy herd size and<br />

season of Fixed factors were compared using the check averages Duncan (15). The physiological characteristics, including<br />

age at first birth, number of days open have been considered Random variables that were factor analyzed using Linear<br />

Regression on the production of milk daily to the animal to take advantage of the statistical program SPSS.6 (24).<br />

Have been analyzed for fixed factors mentioned above as the mathematical model the following:<br />

Y ijk = ? + G i + S j + e ijk<br />

Where:<br />

Y ijk = the amount of viewing (the amount of milk daily in the season breeders k of the group i<br />

Results and Discussion<br />

Herd size and the distribution of attributes<br />

Seen from tables (1 and 2) the distribution of the total herd size and statistical measures of the attributes studied.<br />

<strong>MILK</strong> <strong>PRODUCTION</strong><br />

Table 1: Distribution of the number and proportion of farmers among the groups of numbers in the sample<br />

The group * number of farmers Percentage<br />

* Number of animals in one group as shown in the search mode<br />

Seen from the table (1) that about 50% of herds is between the small to medium-sized, ranging number of buffalo in one<br />

herd between 4 to 20, the head normally. The remaining of the herds, approximately 25% of which ranged in size from 20<br />

to 40 head, 25% include herds with more than 40 the number on the upside, knowing that the smallest herd size was 4<br />

headers and the largest herd shown in this study was the size of 253 head.<br />

Though this distribution to the size of the herd in the area of search may not be much different than it is in other parts<br />

of Iraq (private data), but it is much different than is the case in other countries. In Italy, which has a population where<br />

the buffalo to 265 thousand head, the average herd size to 50 head. In Bulgaria, which has 92 thousand head of buffalo,<br />

which was soon to follow the system of cooperative farms, increase the size of the herd to 500 head, applying modern<br />

methods of raising and production and manufacture of milk into the structure of the products with high specifications.<br />

As for Turkey, which reduced the number of buffaloes from approximately 1 million to 110 thousand head, the herd size<br />

ranging from 1 to 15 animals. In Egypt, where there are about 4 million head of buffalo, participate in the production of<br />

65% of the total milk produced in this country, the average herd size is not more than 3 buffalo normally. In India, which<br />

is at the forefront of countries in terms of the number of buffalo (95 million head), 85% of this number is in the hands<br />

of small farmers in the form of herds ranging from 1 to 5 heads. And are similar to Iran, which has a 500 thousand heads,<br />

with Iraq in terms of the modalities of raising and the size of the individual property of buffalo ranging from 5 to 100<br />

head (17, 20).<br />

Seen from the table (2) the average of the attributes studied, regardless of the factors influencing them. Did not differ<br />

in daily production rate of milk in this site a lot of what indicated by other studies on Iraqi production of buffalo milk<br />

during the period of years. He pointed Williamson (27), Juma (21, 22), Desouki (3) that the daily productivity of buffalo<br />

milk ranging from 5 to 6 kg. He cited Kassir (23) values are similar, while M El-Dessouky (16) in another study on a village<br />

buffalo white gold, that the daily milk production per buffalo ranged from 6 to 10 kg.<br />

Capacity and the number of observations (average ± standard deviation)<br />

Daily production of milk (kg)<br />

In the latest study of Iraqi buffaloes in southern Iraq, said Edris and his group (1) that the average daily production of<br />

milk in buffaloes fed the traditional way, which is about feeding on common reeds, rice straw (Alboh) and remnants of<br />

mills at different rates, depending on the financial condition of the breeders and the level of education, was 5.67 kg,<br />

this production has risen to 8.40 kg, has been modified when the daily diet of the herd to provide alpha alpha,<br />

amounting to 12 kg / head per day, with 6 to 8 kg of feed concentrate consisting of barley, 37%, Maize 15 %, 40% wheat<br />

bran, brocken rice 5%, calcium 2% salt 1%.<br />

When comparing these rates with rates of Buffalo global productivity, we find that the production of buffalo Indian,<br />

Italian and Pakistani is 7 kg per day, with reference to this is the overall rate of the herd in these countries, and there<br />

is a distinct herds of more than 20 daily output, and there are some individuals outstanding to 30 kg, depending on the<br />

breed and diet (11, 12, 14, 19).<br />

It also should be noted that we found a number of individuals in the search area the rate of daily output to 20 kg, which<br />

informs that there are some distinct genotypes, which can be used in the process of genetic improvement in the future.<br />
