Abstract

The objective of this work was to demonstrate the effects of exogenous injectable progesterone on protocols of induction and estrus cycle synchronization in sheep. The production of these animals has shown to be increasing in the state of Bahia, impelling the need for new techniques applied to reproductive management to raise the rate of productivity of the herds. Thus, two hormonal protocols of short duration were conducted in 17 Santa Inês breeders. Two groups were submitted to combination of Progesterone Injection, Equine Chorionic Gonadotrophin(eCG) and Clorprostenol Sodium as precursor of Prostaglandin 2α(PGF2α), differing in doses and application interval. The results obtained in relation to estrus presentation were not significant, since parity indexes had a negative influence after the protocol.
