Efficacy of GnRH-Prostaglandin-GnRH Schedule in Management of Postpartum Anestrus and Subestrus Jafarabadi Buffaloes

Twelve postpartum Jafarabadi buffaloes of University farm were examined gynaecologicallybetween months of February and May 2016 and were found to be either anestrus with smoothovaries (n=8) or subestrous (n=4) with functional corpus luteum. All the 12 animals irrespective ofovarian status were injected i/m with Busreline acetate 20 ?g (Receptal, 5 ml) on day 0, Cloprostenol500 ?g (2 ml) on day 7 and were inseminated twice after 72 and 84 hrs. Second injection of Receptal2.5 ml was given at the time of 2nd insemination. Six buffaloes returned to estrous on 21st day followinginsemination which were reinseminated twice at 12 hours interval on reported estrous and injectedwith 2.5 ml Receptal. Pregnancy diagnosis was done two month post-insemination and conceptionrate of 50.00% (6/12) to first insemination and 33.33% (2/06) to second insemination was obtained.The overall conception rate obtained was 66.66% (8/12). Thus from the above facts, it can be saidthat this schedule of modified GnRH-PG-GnRH appears to work effectively in infertile Jafarabadibuffaloes with good conception rate.
