Abstract: The aim of the present study was to induce synchronized estrus by short-term progestagen treatments plus PMSG at nulliparous ewes from the breed Synthetic Population Bulgarian Milk at the beginning of the estrus season. The experiment was carried out with 30 ewes, divided in 3 groups (each group – n=10). I group – vaginal sponge impregnated with 30 mg FGA for six days, as at the time of the placement of the sponge 125 μg cloprostenolum was put i.m. At the time of the removal of the sponge, 300 UI PMSG was put i.m.; II group – the same as the I group, but without cloprostenolum treatment; III group – control. The applied schemes had good synchronized effect, but low fertility (90% and 66,67%, 22,22% and 33,33 respectively for Group I and Group II).
