چکیده مقاله:

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
