چکیده

the study was undertaken to compare the efficacy of an estradiol-17β + cidr based protocol with the conventional ovsynch + cidr based protocol for synchrony of wave emergence and ovulation in murrah buffalos. in group i (n=25), on day 0 (beginning of experiment), buffaloes were administered a cidr device (1.38 g p4) and concurrently received 1.5 mg e-17β. on day 9, the cidr was removed and a prostaglandin (pg) f2α analogue (500 μg) was administered. on day 11, buffaloes were administered agonadotropin releasing hormone (gnrh) analogue (20 μg) and inseminated twice at 12 h and 24 h following gnrh injections. group ii (n=25) protocol was based on an ovsynch regimen plus cidr for 7 days followed by double insemination at induced estrus. group iii (n=10) served as control and was not given any hormone on day 0 of the protocol. in groups i, ii and iii, the duration of new follicular wave emergences were observed on days 4.22 ± 0.12, 3.12 ± 0.33 and 5.14 ± 0.42, respectively. in group i, synchronyof wave emergence was more and the diameter of pre-ovulatory follicles was larger (p
