Abstract: The first stet for applying superovulation is to know the responsiveness of the ewe to different estrous synchronous protocol duration and possible implications on embryo yield. On the other hand for nonsurgical embryo recovery (NSER) a well consolidated protocol should be tested and, in Morada Nova ewes, successful non-surgical uterine access was reported (Fonseca et al., 2019. Reprod Fertil Devel, 31:17-26). In this context, the objective of this study was to evaluate the efficiency different synchronous estrus induction and NSER as additional tool to evaluate the results these protocols in pluriparous Morada Nova ewes. A total of 18 pluriparous sheep were divided into three treatment groups with 6 (T6, n=6), 9 (T9, n=6) and 12 (T12, n=6) days of 60 mg of medroxyprogesterone acetate (Progespon®, Zoetis, Campinas, São Paulo, Brazil). The NSER mean duration was 27.6±1.4 min, with recovery of 99.8% of injected fluid and embryo recovery rate of 62.97% (17/27). These preliminary results indicated that all protocols provided similar results and that NSER can be successfully performed and used as additional toll in synchronous estrous induced Morada Nova ewes independently from the duration of progestogen regimen to assure that viable embryos can be produced by ewes subjected by these protocols.
