The study was undertaken to find out the estrus induction and conception rate in 18 postpartumanestrus Surti buffaloes divided equally into three groups and treated with Ovsynch protocol aloneand in combination with PRID, keeping one group as control. The use of Ovsynch alone and Ovsynch+ PRID protocols with fixed-time artificial insemination resulted in 100% estrus induction with 66.66%and 50.00% conception rate at induced estrus, respectively, and the overall conception rate was83.33% in both the groups. In untreated anestrus control (n=6), only four (66.66%) buffaloesexhibited spontaneous estrus within 120 days of follow-up and conceived giving the first serviceand overall conception rate as 75.00% and 66.66%, respectively. The mean number of servicesper conception did not differ significantly among the treatment and control groups. The serviceperiods of buffaloes under both the treatment groups were significantly (p less than 0.05) shorter (57.00±2.81and 61.20±3.11 days) than the control group (104.00±20.22 days). Thus, the Ovsynch and Ovsynch+ PRID protocol can be successfully used to induce fertile estrus in postpartum anestrus buffaloes.
