Background and Aim: The main objective of this study was to estimate the effect of supplementation of rumen-protected choline (RPC) and green tea extract (GTE) on production parameters in transition Karan Fries (KF) cows.

Materials and Methods: The present experiment was carried out on 32 pregnant KF cows. In the control group, cows were fed basal diet. In T1, each cow was fed RPC (55 g/day), in T2 – GTE (3 g/d), and in T3 – RPC + GTE (55+3) g/day along with basal diet. The duration of the experiment was 30 days before calving to 60 days after parturition.

Results: Feeding of both RPC and GTE significantly increased milk yield (p≤0.01), 4% fat corrected milk yield (p≤0.01), milk fat (p≤0.01), and total solid content (p≤0.05) than control. There was no significant difference (p≥0.05) in milk protein, lactose, and solids not fat ( SNF) content among the groups.

Conclusion: Supplementing RPC and GTE in combination improved milk yield and fat content of the milk without altering protein, lactose content of the milk in transition KF cows. Keywords: green tea extract, milk fat, milk yield, production, rumen-protected choline, transition Karan Fries cows.
