Abstract:

The reproductive ability of buffalo is reduced during summer season. The present study was conducted on 60 postpartum cyclic buffaloes (>45 days in milk) to assess the ovarian activity and fertility rate following modified Heatsynch protocol. The study was conducted during summer (May-July, n=30) and winter (December-February, n=30) seasons. In group I, a PGF2α (Cloprostenol, 500 mcg) was administered on day -14, -2 and 7. A gonadotropin releasing hormone (GnRH: Buserlin acetate, 10 mcg) was administered on day 0 and estradiol (Estradiol benzoate, 1 mg) on day 8 followed by timed artificial insemination (TAI) 48 h later on day 10. In group II, first 2 PGF2α injections were not administered; however, rest of the treatment was similar to group I. The ovulatory response following estradiol benzoate administration was comparable in both groups during summer (86.66 vs. 80.00 % in group I and II, respectively) and winter (100.00 vs. 100.00 % in group I and II, respectively) seasons. However, conception rate was on higher side in group I (60.00 %) compared to group II (26.66 %) buffaloes in summer season. In winter season conception rate was 73.33 and 53.33 percent in group I and II, respectively. The present findings indicated that Presynch-Heatsynch treatment may increase the conception rate in buffaloes during summer season as compared to Heatsynch treatment.
