Abstract

The objective of this study was to obtain the appropriate dose of PMSG hormone to use in the heat synchronization method during the breeding season of Anatolian Merino sheep. The animal material consisted of 100 heads of Anatolian Merino sheep. Choronogest® sponges containing 20 mg of fluorogestone acetate were applied to all sheep which lasted for 12 days. Then the sponges were removed, and the animals were divided into two groups with equal numbers (n=50). The first group received 300 IU PMSG (application I, n=50) and the second group received 600 IU PMSG (application II, n=50) intramuscularly. Sheep were mated at 96h following the PMSG application. Lambing rate was 94% in the treatment I group and 96% in the treatment II group (P<0.01). Single and twin birth rates were higher in the application II group than in the application I group (P<0.01). The infertility rate was found to be lower in the treatment II group than in the treatment I group (P<0.01). As a result, using 600 IU PMSG hormone in the application of estrus synchronization during the breeding season in sheep ensures better fertility results.
