The objective of this study was to investigate the effect of betaine supplementation in improvement of reproduction parameters in crossbred Karan Fries cows during hot humid season. Eighteen pre-parturient Karan Fries cows were selected and classified into two groups (n=9) as control and treatment (betaine supplemented) on the basis of body weight and parity. Control group was fed basal diet alone and in treatment group along with basal diet, 50g betaine anhydrous (betafin® S1) per cow per day was supplemented. Average Temperature Humidity Index (THI) during whole experimental period was ± units indicating that all experimental cows were under heat stress. | Effect of dietary betaine on reproductive performance of Karan fries cows during hot humid season
