Summary: The use of multiple ovulation and embryo transfer (MOET) program in sheep is limited by anatomical particularities of ovine cervix, making non-surgical embryo collection method (transcervical) more difficult or even impracticable. Therefore, the cervical morphology screening prior MOET becomes an interesting strategy. Thus, this study aimed to evaluate a cervical transposition method as a tool to select ewes able of being submitted to non-surgical embryo collection. The high SENS and Acc verified in the study demonstrated that cervical transposition test at the estrus using a Hegar dilator has the potential to be included in MOET programs as a screening strategy to direct ewes for a surgical or non-surgical embryo collection
