Abstract :This study was carried out in Kıvırcık ewes to increase reproductive performance and synchronize oestrus by using progestagen pessaries (40 mg FGA) and different doses of PMSG (0, 500 and 700 IU) during the breeding season. Free mating occurred in the herd and 76% of all births were completed in the first week. Fertility, single birth rates, fecundity and prolificacy in the three different groups were found to be 94.87%, 96.66% and 100.00%; 78.38%, 55.18% and 38.46% (PKeywords : Progestagen, PMSG, Kıvırcık ewes, Reproduction characters
