Abstract:
Fifty Indigenous and graded buffaloes between 1st and 4th parity showing postpartum ovarian acyclicity for 120 days or more, were selected for the study. The true anestrous animals were treated with two different hormonal protocols viz. Double synch (Group A, n=20) and Estra-double synch (Group B, n=20) protocols along with routine vitamin and mineral supplements and Group C (n=10) as control group with only routine vitamin and mineral supplements for 2 weeks. Buffaloes induced by double synch therapy (group I) yielded 70 per cent oestrus response, induction interval (hour) was 69.63 ± 1.86, duration of estrus (hour) was 16.31 ± 1.56 and conception rate was found to be 57.74 per cent. The buffaloes which were subjected to estra-double synch protocol (group II) recorded estrus response in 80 per cent (16) cases with corresponding induction interval of 62.67 ± 1.74 hour, duration of estrus was 18.13 ± 1.28 hours and the conception rate was 62. 50 %. Lowest oestrus response of 20 per cent was observed in untreated, where the average induction interval was 260.40 ± 3.46 hrs and of duration of estrus was 11.25 ± 2.25 hour with 50 per cent conception rate. From the above light of study it may be concluded that double synch and estra double synch protocols are worthy, successful and valuable for induction of estrus in post partum anestrous buffaloes.
