Effects of PMSG application time on fertility in estrus-synchronized Kilis goat lambs out of season

Öz

Since their reproduction is seasonal, goat lambs can not mate before the breeding season begins, even if they have reached breeding maturity. This situation leads to economic losses for farmers. Estrus synchronization with progesterone and PMSG combination is widely practiced to produce off-season heat. However, different applications are made regarding the dose and timing of PMSG. In the study, the effects of PMSG (500 IU) administration at two different times on estrus and pregnancy rates and the number of offspring were investigated in estrus-synchronized goat lambs. Twenty three kilis goat lambs 13-15 months old that had never mated before were treated (out of season) with a progesterone sponge (20 mg flugestone acetate) for 11 days and 250 mcg PGF2α two days before sponge removal. While PMSG was applied to lambs in group 1 (n:11, hour -48 group) two days before sponge removal, it was applied to lambs in group 2 (n:12, hour 0 group) on the day of sponge removal. Goat lambs standing to be mounted were considered in estrus and mated. All goats in both groups showed estrus. The pregnancy (lambing) rate (54.6% vs. 25.0%, respectively, P>0.05) and total number of offspring (7 vs. 3, respectively, P>0.05) of the 1. (hour -48) group were found numerically higher than the 2. (hour 0) group, but the differences between groups were not statistically significant. Considering the economic values of numerical increase in the pregnancy rate and the total number of offspring, it was concluded that it may be more beneficial to apply PMSG 48 hours before the sponge removal rather than at the time of sponge withdrawal out of the breeding season in Kilis goat lambs.
