Abstract

A total of forty five postpartum buffaloes were equally divided into group I, II and III. The
group I animals were treated with PGF2alpha  after palpation of corpus luteum. The group II animals were
treated with CIDR and removed after 9 days. The group III animals were treated with GnRH analogue
and 6 days later they were administered with PGF2alpha . A second injection of GnRH analogue was
administered after 48 hours of PGF2alpha  treatment. Percentage of induced estrus were 66.6%, 86.6% and
60.0% in group I, II and III, respectively. Mean onset of induced estrus were 54.4 ± 7 .6, 42.2 ± 6.6 and
47.4 ± 8.4 in group I, II and III, respectively. First service conception rate was 50.0%, 46.1 % and
66.6% in group I, II and III, respectively. From this it may be concluded that Ovsynch protocol is giving fertility rate upon fixed-time breeding in estrus synchronized buffaloes at field level.
