Abstract

The aim of the present study was to compare the
effect of two estrus synchronization treatments i.e.,
Ovsynch alone and Ovsynch plus Controlled Internal
Drug Release (CIDR), on the occurrence of estrus and
conception rate in Kundhi buffalo during breeding
season in Pakistan. Forty Kundhi buffaloes were
randomly selected and were divided into three
groups; Group A (n=16; Ovsynch) received 2 mL
GnRH intramuscularly (i/m) on day 0 and 9. On day 7,
5 mL prostaglandin F2? (PGF2? analogue) was
administered through i/m route. The buffaloes of
Group B (n=17; Ovsynch+CIDR) received 2 mL
GnRH on day 0 along with implantation of CIDR. On
day 7, the CIDR was removed, and 5 mL PGF2?
analogue was injected through i/m route. A second
dose of GnRH was administered through i/m route
after 48 h of PGF2? inj. in both groups. Group C (n=7;
control) received 2 mL normal saline through i/m
route on day 0, 7 and 9. The buffaloes of all three
groups were artificially inseminated twice (12 h and
24 h after the second GnRH inj.) using frozen-thawed
semen. Estrus response differed significantly (P<0.05)
among the groups. The animals of Group B (76.47%)
showed superior estrus response as compared to
others. Higher conception rate (52.94%) was observed
in the animals of Group B; however, the difference
was not significant. In conclusion, Ovsynch+CIDR
causes to occur better estrus response and conception
rate as compared to Ovsynch alone in Kundhi
buffaloes during breeding season.
