Effects of hCG administered 7.5 days after synchronous estrus induction during the non-breading season in Morada Nova ewes.

Effects of hCG administered 7.5 days after synchronous estrus induction during the non-breading season in Morada Nova ewes.

This study was designed to assess the effects of human chorionic gonadotropin (hCG) administration 7.5 days after the end of synchronous estrus induction protocol in Morada Nova ewes in the non?breeding season on biometrics and vascularization of the luteal tissue, progesterone (P4) concentrations and reproductive performance. Morada Nova ewes (n=113) were submitted to synchronous estrus induction, during October and November, with 60 mg medroxyprogesterone intravaginal sponge for sex days plus 200 IU of eCG i.m. and 30 ?g of d?cloprostenol i.m. 36 h before sponge removal.
