Supplementing Rumen Protected Choline with Green Tea Extract Exerts Hepatoprotective Effect in Transition Karan Fries Cows by Modulating Serum Biochemistry

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/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. The plasma non-esterfied fatty acids (NEFA) concentration reduced significantly (p ≤ 0.01) in T1, T2 and T3 than control from the day of parturition up to the end of experiment. The cows supplemented with RPC and GTE showed a trend towards decreased plasma beta- hydroxy butyric acid (BHBA) (p ≤ 0.01) than control. No significant (p ≥ 0.05) difference was observed across the groups for plasma cholesterol and blood urea nitrogen (BUN) concentration. Plasma aspartate amino transferase (AST) concentration reduced significantly (p ≤ 0.05) in T1, T2 and T3 as compared to control from 0th day to 15th day of parturition. The concentration of plasma triacylglycerol (TAG) and very low-density lipoprotein (VLDL) increased significantly (p≤ 0.01) in T1 and T3 as compared to control. In conclusion, feeding of RPC and GTE in combination improved hepatic performances during transition period in Karan Fries cows.
