Abstract:
The Present investigation was conducted on eighteen pregnant Karan Fries (Holstein Friesian × Tharparker) cows and was divided into three equal groups. Control group was fed with only basal diet. T1 and T2 group was fed with basal diet along with 250 ppm and 500 ppm Boron/day from 30 days before to 60 days after calving. Temperature humidity index, reproduction parameters were calculated and analysed. There was significant (P<0.05) reduction in postpartum oestrus interval, days of first observed estrum, service period and number of services per conception and significant (P<0.05) increase in the size of dominant follicle was observed by ultrasonography. Increase in conception rate, reduced incidence of retention of placenta, postpartum metritis was noticed in boron supplemented groups. Hence supplementation of boron at both levels found to be effective in improving reproductive performance of Karan Fries cows during hot humid condition.
Highlights
- Boron supplement reduced postpartum oestrus interval, days of first observed estrum, service period and number of services per conception
- Boron supplementation increased the size of dominant follicle.
