On the last day of each period, blood samples were taken at 5h after feeding from the jugular vein of each sheep, alternating sides at each collection. The blood was collected in a 10-ml Vacutainer tube (contain heparin), and blood pH and CO 2 were analyzed within 1h. Blood samples centrifuged at 3000 xg for 20 min and plasma was used to analyze glucose and lactate dehyrogenase (LDH).

Abdi benemar, K. Rezayazdi, A. Nikkhah University Of Tehran, Animal Science Department, Karaj, Tehran, Iran Introduction: Ration particle size has been observed to affect DMI, milk fat and protein content and milk yield. Nonforage fiber sources (NFFS) possess a large amount of NDF that can be used as a forage substitute based on their price and availability. Cottonseed hulls (CSH), a by-product of cotton processing, contain a large proportion of NDF and associated lignin, and have been considered a useful NFFS. It was suggested that physical characteristics of dietary forage can interact with nonforage fiber sources. The objectives of this study were to determine effects of CSH as nonforage fiber sources and to investigate interaction between CSH as NFFS and alfalfa particle size on DMI, milk fat and protein content and milk yield. Materials and methods: Twelve Holstein dairy cows in midlactation were assigned to a change-over design with three periods and 2_2 factorial arrangement of treatments. During each of 28-d periods, cows were offered one of four total mixed rations that differed in alfalfa hay particle length (long and short) and cottonseed hulls substituted for AH (0 and 9.63% DM. Cows were housed in tie stalls and fed twice daily at 0800 and 1400 h for adlibitum consumption. Milk yield was recorded twice weekly and milk samples analyzed for fat and protein content. Data were analyzed using the mixed model procedure of SAS (1998) with model effects for period, alfalfa hay particle length (APL), fiber source (FS) and two-way interaction of APL by FS as fixed effects and cow as random effect and effects of factors were declared at P < 0.05. Results: Dry matter intake was not affected by either APL or substitution of CSH. Milk yield, 4% FCM, and percent of milk fat and milk protein were not affected by either APS or substitution of CSH Table 1.

Jubilee World Buiatrics Congress 2008 A. Formigoni, N. Brogna, F. Merendi, A. Mordenti, G. Biagi University of Bologna, DIMORFIPA, Ozzano emilia, Italy Conjugated linoleic acid (CLA) is a nutrient that can exert several beneficial effects on the health of consumers and is mainly found in meat and dairy products from ruminants. In order to characterize the lipid fraction of Parmigiano-Reggiano cheese, 255 samples of cheese were analyzed. Samples differed for geographical origin (different provinces constituting the Parmigiano-Reggiano cheese area of production), altitude of the cheese factory location (plain, hills or mountains; P, H or M), and seasoning time (< 22 months, between 22 and 30 months, or > 30 months). All samples were analyzed for their lipid content and fatty acids composition. Total lipid content of cheese was not influenced by any of the variables considered and averaged 24.4 %. Content of all fatty acids was not significantly affected by seasoning time. In particular, content of CLA averaged 0.32 mg/100 mg of fat. The altitude of the cheese factory location had a significant influence on the concentration of several fatty acids. Cheese samples coming from factories located on mountains showed significantly (P < 0.05) higher concentrations of C18:0 (stearic acid; 6.1 vs 5.5 and 5.3 mg/100 mg of fat for M, H and P, respectively), C18:1 cis (oleic acid; 13.0 vs 11.5 and 11.5 mg/100 mg of fat for M, H and P, respectively), C18:1 trans (vaccenic acid; 1.04 vs 0.89 and 0.76 mg/100 mg of fat for M, H and P, respectively), and CLA (0.37 vs 0.32 and 0.28 mg/100 mg of fat for M, H and P, respectively). Similarly, the concentration of some fatty acids was influenced by the province of origin, but this effect seemed to be mainly related to the different presence of cheese factories located on mountains in each province. The present results show that the area of production of Parmigiano-Reggiano cheese significantly influences its lipid fraction. In particular, cheese from factories located on mountains show a higher content of CLA and vaccenic acid, probably due to a higher utilization of green forages which are very rich in linoleic and ·-linolenic acid, both precursors of CLA. Key words: dairy cow, Parmigiano-Reggiano cheese, conjugated linoleic acid, fatty acids 1235 Adrenal Weight and Morphology in Different Ages of Cow A. Mohammadpour Ferdowsi University of Mashhad, Faculty of Veterinary Medicine, Department of Anatomical Sciences, Mashhad, Iran Eighty pair of adrenal glands in Holstein breed cow was histomorphometrically studied in four different age groups included: 6 month to 9 month, 9 - 12 month, 12 - 15 month and 15 - 18 month ages. After collecting the glands and weighting them, some parameters such as: length, wide and thickness of left and right adrenal were measured by calliper device. For histological studies, after tissue preparation and staining with H&E, cortical and medullar zones were measured. At results, data between left and right adrenal glands in the four ages were analyzed and compared using ANOVA and t-student tests. In Holstein cow the left adrenal gland was been C shape and right adrenal gland was been V shape. There was significant difference between dimensions of left and right adrenal glands. The mean weight, length, wide and thickness of left adrenal gland were greater than right in four ages. In comparison between different age groups there was a significant difference in all of parameters between ages 6 to 9 month and 15 - 18 month (P
cows mainly depends upon roughage, straw etc. that provide mostly carbohydrate. Fodders like cereal grains, rice polish etc. are highly expensive and beyond the reach of marginal farmers, so they are unable to supply these to their cows and their cows suffer from protein, mineral and vitamin deficiency. Iodine is necessary for thyroxin production that has a positive effect on milk yield. Considering it this experiment was conducted to find out a cheapest way of increasing milk yield. A total of 20 indigenous dairy cows of about 3-5 years old, weighing from 120-190 kg were selected based upon history at the day of parturition and were randomly divided into 4 groups. Group A acted as control, and Group B, C and D were treated with non-iodide salt at 100 mg/kg bd. wt. PO daily once, iodide salt at 100 mg/kg bd. wt. PO daily once and Lugol’s iodine at 10 mg/kg bd. wt. IV twice a month, respectively. All the cows were maintained in a similar fashion. Milk yield were recorded daily for 5 months and all the data were analyzed statistically at the end of experiment. Significant (p
