<strong>and</strong>omly assigned to one of five treatments. Four <strong>and</strong> two weeks<br />
before expected calving, the heifers were injected intramuscularly 0 ml<br />
(T0), 10 ml (T1), 20 ml (T2), 30 ml (T3), 40 ml (T4) selenium <strong>and</strong><br />
vitamin E respectively. The control (C) group received no supplement.<br />
Blood samples were collected from heifers four weeks before expected<br />
calving <strong>and</strong> at calving day. Blood samples of calves were drowning<br />
from the jugular vein at birth <strong>and</strong> 7 days of age. Serum concentrations<br />
of Se were determined using hydride generation Atomic absorption<br />
Spectrophotometer. The result indicated that the serum concentration<br />
of Se, Cu <strong>and</strong> Fe increased in T3 <strong>and</strong> T4 treatment heifers at calving<br />
day but no change seen in serum concentration of Zn. Serum Cu<br />
concentrations in calves of treated groups increased at birth <strong>and</strong> first<br />
week of age but was not significantly different. The serum<br />
concentration of Cu <strong>and</strong> Fe increased in calves of heifers given Se <strong>and</strong><br />
vitamin E compound esp. in T3 <strong>and</strong> T4 treatments but the serum<br />
concentration of Zn decreased. It seems that the Zn: Cu <strong>and</strong> Zn: Fe<br />
ratios be disturbed which lead to Zn reduction. It can be concluded that<br />
Zn should be supplemented when more than 40 mg/Kg Dm<br />
administered to pregnant heifers.<br />

Fibrolytic enzymes are typically cellulase that degrade cellulose or<br />
xylanase that act on hemicellulose (Beauchemin et al., 1995). Enzymes<br />
applied to forages immediately before incubation enhance the digestion<br />
of dry matter (DM) <strong>and</strong> neutral detergent fiber (NDF) suggesting that<br />
fibrolytic enzymes applied at feeding can improve digestion in<br />
ruminants.<br />

Five Gezel male lamb treated with 4 levels of monensin (0, 10, 30, <strong>and</strong><br />
60 mg/kg of diet) in a change-over design. Blood samples were taken<br />
one hour before <strong>and</strong> 2 hrs after feeding. Serum was separated <strong>and</strong><br />
freezed up to analysis. Serum levels of glucose, beta-hydroxy-butyrate,<br />
triacylglycerol, total protein, albumin (albumin/ globulin), <strong>and</strong> blood<br />
urea nitrogen (BUN) was measured by colorimetric methods.<br />
Considering liver health, serum activity of AST, ALP, <strong>and</strong> GGT was<br />
measured. Ruminal fluid sample was taken for pH analysis<br />
(ruminocynthesis). Total <strong>and</strong> differential white blood cell count <strong>and</strong><br />
phagocytosis test undertaken. Results of this study showed that<br />
monensin in a level of at least 30 mg/kg of diet could effectively inhibit<br />
acidosis occurrence. Acidosis has a negative effect on appetite; acidotic<br />
animals have lower levels of glucose in serum. But, monensin does not<br />
have any independent positive effect on serum glucose. Even two-folds<br />
of this dosage had no negative effect on liver. Monensin does not any<br />
stimulatory effect on natural immunity either independently or dosedependently.<br />
Generally staying, monensin may be inhibiting acidosis<br />
elated complications such as natural immune depression.<br />

The aim of our work was the investigation of influence of different doses<br />
(210 <strong>and</strong> 420 IU D 3/kg body weight) of vitamin D 3 on vitamins status of<br />
cows in preparturient <strong>and</strong> postparturient periods under the parenteral<br />
18 XXV. Jubilee World Buiatrics Congress 2008<br />
injection of vitamin D 3 once before calving <strong>and</strong> three times after calving<br />
with interval of seven days. The experiment was carried out on the three<br />
groups of cows of Black-<strong>and</strong>-White breed, 5-6-years-old age, in a winterspring<br />
period. The cows of first group, to which vitamin D did not<br />
injection governed as control. To the cows of 2-nd <strong>and</strong> 3-rd groups the<br />
vitamin D 3 was injected intramuscularly in abovementioned doses. In<br />
blood the level of 25-hydroxyvitamin D, the concentration of calcium,<br />
magnesium, inorganic phosphorus, the activity of total alkaline<br />
phosphatase <strong>and</strong> its isoenzymes at 3-5 days before calving, 5-7 days <strong>and</strong><br />
55-60 days after calving were determined. It was established, that the<br />
content of 25-OH D 3 in the blood serum of cows of 1-st, 2-nd <strong>and</strong> 3-rd<br />
groups at 3-5 days before calving was correspondently: 18,75; 25,95 <strong>and</strong><br />
32,85 nmol/l, <strong>and</strong> at 5-7 days after calving 15,83; 20,83 <strong>and</strong> 31,88 nmol/l.<br />
At 55-60 day after calving the concentration of 25-OH D 3 in blood serum<br />
of cows was the greatest <strong>and</strong> varied from 20,48 till 35,0 nmol/l. Thus in<br />
the cows blood of 2-nd <strong>and</strong> 3-rd groups before <strong>and</strong> after calving dose<br />
dependence increase of concentration of calcium of total, protein-linked<br />
<strong>and</strong> ultra-filtrates was observed. The concentration of magnesium in the<br />
blood of cows of 3-rd group in the 5-7 day after calving was statistically<br />
significantly higher about 19%, <strong>and</strong> in the 55-60 day about 6 %,<br />
comparatively with the control. At the same time, in the blood of cows of<br />
2-nd <strong>and</strong> 3-rd groups, comparatively with the control group, dose<br />
dependence increase of concentration of inorganic phosphorus <strong>and</strong><br />
decrease of the activity of alkaline phosphatase <strong>and</strong> its isoenzymes (bone<br />
<strong>and</strong> intestinal) was observed. Parenteral injection of cholecalciferol to<br />
cows before <strong>and</strong> after calving maintained the level of 25-OH Vit D 3 <strong>and</strong><br />
effected on the exchange of mineral components of blood, that prevents<br />
the decrease of their level in postparturient period. The character of these<br />
changes depend on the physiological state of cows <strong>and</strong> on the doses of<br />
vitamin D 3.<br />

The correlationship between food intake, hypophosphatemia, blood<br />
contents, pregnancy <strong>and</strong> health condition were done in 35 bufalloes 2-<br />
4 months before parturation at 7-9 years old (9 healthy as a control,12<br />
with clinical <strong>and</strong> 14 with subclincal hypophosphatemia according to<br />
blood , serum <strong>and</strong> feed analysis <strong>and</strong> clinical examination).<br />
Analysis of feed stuff revealed a lower level of phosphorous, a higher<br />
level of calcium <strong>and</strong> molybdenum with a normal level of copper.<br />
Clinical cases of hypophosphatemia showed normal temperature,<br />
elevated pulse <strong>and</strong> respiration, sluggish rumen movement, depraved<br />
appetite, pica, dullness, emaciation, red haemoglobin urine <strong>and</strong> pale or<br />
sometimes icteric mucosus membrane.<br />
The subclinical cases showed a normal temperature, pulse, respiration,<br />
depraved appetite, dullness <strong>and</strong> sometimes locomotors disturbances.<br />
The blood level of hemoglobin content <strong>and</strong> PCV were significantly<br />
decreased in clinical cases only.<br />
Serum levels of inorganic phosphorous was highly significant<br />
decreased with a decrease of serum copper level in clinical cases <strong>and</strong><br />
significantly decreased of phosphorous in subclinical cases. Serum<br />
calcium <strong>and</strong> molybdenum levels were significantly increased in clinical<br />
cases <strong>and</strong> slightly increased in subclinical cases. Serum magnesium,<br />
sodium, potassium <strong>and</strong> chloride showed a non significant changes in<br />
clinical <strong>and</strong> subclinical cases.<br />
Treatment with Sodium dibasic phosphate (60 gm diluted in 300 ml<br />
distilled water was given 4 times within 12 hours intervals, The first<br />
injection was intravenous, the others was subcutaneous) as well as<br />
daily 20 ml catozal intravenous <strong>and</strong> 250 gm bran <strong>and</strong> 10 gm copper<br />
sulphate per os in food for one week was satisfy for treatment the<br />
clinical cases. Subclinical cases were treated with oral daily of 30 gm<br />
sodium dibasic phosphate, 125 gm of bone meal <strong>and</strong> 2-4 kilogram of<br />
brain for a period of one month. Correction of feed supply was helpful<br />
<strong>and</strong> advised in both cases. It is concluded that diet, blood <strong>and</strong> serum<br />
analysis <strong>and</strong> the general health condition were helpful for diagnosis of<br />
clinical <strong>and</strong> subclinical hypophosphatemia in pregnant buffaloes,
