Abstract:
Present work was carried out to study the effect of hormonal regimens, together with vitamin E and selenium on estrus induction and fertility response in pubertal anestrus buffalo heifers. A total of 24 buffalo heifers were selected and equally divided into two groups. Heifers in Group I were treated with Ovsynch protocol, whereas Group II heifers were treated with Ovsynch plus antioxidants (Vitamin E and Selenium) at a dosage rate of 1 ml/50 kg body weight. In both treatment groups, the response to estrus induction was 100 per cent. Time required for onset of estrus ranged between 40 to 65 and 40 to 62 hrs. with an average of 50.17±2.66 and 47.83±1.92 hrs. In Group I and Group II, the duration of estrus was 21.42±0.62 hours and 22.17±0.66 hours, respectively. Intensity of estrus was Intense, intermediate and weak in group I as 33.33, 41.66 and 25.00 per cent, while in group II as 41.66, 50.00 and 8.33 per cent, respectively. First service conception rate in group I treated with Ovsynch protocol was 33.33% and in group II treated with Ovsynch protocol along with antioxidant was 41.66% and similarly overall pregnancy rate in group I and II was 58.33% and 66.66% respectively.
Highlights
- Inclusion of antioxidants in Ovsynch protocol improves fertility in pubertal anestrus buffalo heifers.
- Higher first service conception rate is achieved by including Vitamin E and Selenium in Ovsynch protocol.
