S. R. Shendage | R.B. Ambade | S. H. Dalvi | V. M. Sardar


Abstract: The experiment was conducted on 20 Vencob broiler chickens maintained at Bombay Veterinary College, Poultry Unit No 03, Mummbai. The blood samples from these birds were collected from 3rd week of age and then weekly interval till 6th week of age by jugular veinipuncture in the morning hours (10-11 am). The serum samples were analyzed for total proteins, albumin, globulin, albumin-globulin ratio and uric acid, triiodothyronine, Thyroxine and T3:T4ratio.The mean ? SE level of total proteins was 2.96 ? 0.09, 3.08 ? 0.07, 3.07 ? 0.06 and 3.18 ? 0.08 g/dl at 3rd week, 4 th week, 5 th week and 6 th week age of chicken respectively. The mean ? SE level of Albumin were 1.30 ? 0.03, 1.24 ? 0.05, 1.26 ? 0.05 and 1.19 ? 0.02 g/dl at 3rd week, 4 th week, 5 th week and 6 th week of age respectively. The mean ? SE level of Globulin were 1.50 ? 0.07, 1.85 ? 0.09, 1.80 ? 0.08 and 1.97 ? 0.08 g/dl at 3rd week, 4 th week, 5 th week and 6 th week of age respectively. Mean ? SE level of Albumin- globulin ratio were 0.80 ? 0.03, 0.74 ? 0.09, 0.76 ? 0.14 and 0.63 ? 0.03 at 3rd week, 4 th week, 5 th week and 6 th week of age respectively. The mean ? SE level of uric acid were 8.34 ? 0.44, 7.61 ? 0.24, 5.01 ? 0.20 and 5.29 ? 0.28 mg/dl at 3rd week, 4 th week, 5 th week and 6 th week of age respectively. The mean ? S.E. levels of theT3 were 1.41 ? 0.11, 2.03 ? 0.09, 1.97 ? 0.08, and 2.02 ? 0.15 ng/ml during 3rd, 4th, 5th and 6th week of age respectively. The T3 has shown significant increase from 3rd week of the age when growing period of broiler starts.Mean ? SE level of thyroxine (T4) were 10.94 ? 0.73, 8.95 ? 0.50, 8.75 ? 0.58 and 8.03 ? 0.47 ng/ml at 3rd week ,4th week, 5 th week and 6 th week of age respectively. T4has shown declining trends as age advances. The mean ? S.E. levels of T3:T4ratio were 0.15 ? 0.01, 0.24 ? 0.02, 0.26 ? 0.02, and 0.2 ? 0.03 during 3rd, 4t th, 5 th and 6 th week of age respectively.
