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

Abstract

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/day) and in T3- RPC + GTE (55+3g/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 among 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<0.01) and TAC reduced significantly (P≤0.05) in T1, T2 and T3 as compared to control from 7^th day to 30^th day of parturition. In conclusion, feeding of RPC and GTE in combination improved immune status and alleviated oxidative stress during transition period in Karan Fries cows.
