Abstract :This study was carried out in Kıvırcık ewes to increase reproductive performance and synchronize oestrus by using progestagen pessaries insert ignore into journalissuearticles values(40 mg FGA); and different doses of PMSG insert ignore into journalissuearticles values(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% insert ignore into journalissuearticles values(P
