Abstract | A total of 45 postpartum goats were included and allocated into three experimental groups, 15 goats each. Group I was treated with single dose of GnRH (100 μg/goat) at 10-14 days postpartum and PGF2α (125 μg/goat) at 20-24 days postpartum. Group II was treated with only PGF2α (125 μg/goat) at 20-24 days postpartum. Group III was kept as a control group. Serum samples were collected from each group to determine the progesterone concentration. Experimental goats were observed for estrus detection regularly. Shorter uterine involution and kidding interval, minimum service per conception, and highest conception rate was significantly (p≤0.05) found in group I compared with group II and group III. Progesterone level was significantly (p≤0.05) increased in group I in contrast with group II and group III. Current findings revealed that combined use of GnRH and PGF2α made an effective combination for the reduction of postpartum intervals and furthermore, to improve postpartum fertility.
