Abstract: This study hypothesized and tested if the same superovulation protocol and non-surgical embryo recovery (NSER) technique would be efficient to produce and recovery embryos naturalized Brazilian sheep breeds managed in different production systems. It is concluded that the in vivo embryo production is feasible in naturalized Brazilian ewes with the same superovulatory protocol. The results showed (1) the repeatability and efficiency of the superovulatory protocol for ovarian stimulation irrespective to breed, (2) high success of NSER related to both successful transcervical uterine flushing and total and viable structures recovered in Morada Nova, Santa Inês and Somalis ewes and (3) elevated embryo viability for embryos recovered after estradiol-cloprostenol-oxytocin based protocol for cervical relaxation and transposing in sheep.
