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 79.25 ± 0.34 units indicating that all experimental cows were under heat stress. The reproduction parameters studied during the experiment were incidence of retention of fetal membranes (RFM) and metritis, interval from calving to first observed estrus, calving to day of first service, first service conception rate, number of services per conception and service period. The results showed less number of cases of RFM and metritis (11.11%), a significant (P<0.05) reduction in interval from calving to first observed estrus (47.50 ± 7.60 days), calving to day of first service (75.25 ± 2.40 days), significant (P<0.05) increase in first service conception rate (22.22%), significant reduction (P<0.05) in number of services per conception (2.00 ± 0.24) and service period (114.44 ± 6.88 days) in treatment group. It was concluded that betaine supplementation in the diet of Karan Fries cattle results in significant improvement in reproductive performance during hot humid season.
