Abstract: Transcervical transposition in sheep cannot be achieved without any cervical relaxation drug (Gusmão et al., 2007, RevBrasSaúdeProdAn, 8:1-10). The first step testing the viability of cervical relaxation protocol for transcervical embryo transfer in sheep is to check the effect of these drugs on pregnancy. Although combination of estradiol benzoate and oxytocin did not compromise pregnancy establishment, no attempts of cervical transposition was reported in sheep (Lewis, 2010. SheepGoatResJ, 25:21-25). In Brazilian conditions, preliminary study showed that association of hCG with E2-OT association given at expected times for embryo transfer appeared not disturbing pregnancy (Arrais et al., 2018. AnimRep, 15:338), but cervical transposition was not tested.
