Pandey, Poonam | Mishra, Anoop | Agrawal, I S
Rumen fistulated crossbred bullocks (3) were provided 3 dietary treatments viz. T1 (control), T2 (antibiotic) and T3 (probiotic) in a latin square switch over design. In T2, the concentration mixture was supplemented with antibiotic kanamycin @20ppm/head/day and in T3, it was supplemented with probiotic@ 7 g/head/day. There was no change in ruminal pH in T2, where as pH was increased significantly in T3. In the T2, ruminal NH3_N concentration decreased significantly, where as TCA-ppT-N concentration increases significantly in T2 and T3. Blood glucose, hemoglobin, total erythrocyte count, total leukocytes count and packed cell volume percentage were not affected with antibiotic or probiotic supplementation. It was concluded that dietary supplementation of antibiotic and probiotics may provide a favorable rumen environment and improvement in rumen nitrogen metabolism which will lead to overall improvement in production efficiency of animals.
