Green Tea Extract Along with Rumen Protected Choline improves Immune Status by Modulating Oxidative Stress in Transition Karan Fries Cows

The present experiment was carried out on thirty-two pregnant Karan Fries (KF) cows. In control group, cows were fed basal diet. In T1 each cow was fed rumen protected choline (RPC) (55g/day), in T2 - green tea extract (GTE) (3g/d) and in T3- RPC + GTE (55+3)g/day along with basal diet. The treatment was given 30 days before calving to 60 days after calving. No significant (p ≥ 0.05) difference was observed across the groups for somatic cell count. The concentration of total immunoglobulin concentration increased significantly (p≤ 0.01) in T1, T2 and T3 as compared to control. Serum level of TBARS (P
