Rumen Protected Choline along with Green Tea Extract Maintain Glucose Homeostasis in Transition Karan Fries Cows

The aim of this study was to determine the effect of supplementation of rumen protected choline (RPC) and green tea extract (GTE) on glucose homeostasis in transition cows. Thirty-two pregnant Karan Fries (KF) cows were randomly allocated into three groups on the basis of most probable production ability (MPPA) and parity. In control group, cows were fed basal diet. In T₁ group, each cow was fed 55g of RPC/day along with basal diet; cows in T₂ group were fed on basal diet supplemented with 3g of GTE/day and in T₃ group, 55 g of RPC and 3 g of GTE/day along with basal diet was fed. The duration of experiment was 30 days before calving to 60 days after parturition. Non significant difference was observed across the groups for plasma glucose concentration. The concentration of insulin and IGF-1 increased significantly (P≤0.01) in T₁, T₂ and T₃ as compared to control in days’ dependant manner around parturition. In conclusion, feeding of RPC and GTE in combination maintained glucose homeostasis during transition period in Karan Fries cows.
