| Induction of cervical dilation allows efficient non-surgical embryo recovery, depending on the sheep breed, and thus its usefulness needs to be assessed in each breed. This study checked the efficiency of two estrus induction treatments and the feasibility of transcervical embryo recovery in Lacaune ewes. In conclusion, both estrous induction treatments showed a high rate of estrus and ovulation, but the dosage of 400 IU of eCG seems excessive. The protocol for cervical relaxation was efficient to allow the transcervical embryo recovery of Lacaune ewes. |

| Abstract: The degree of completeness and interdigitation of the cervical rings affects cervical passage, which is a necessary step for transcervical embryo collection. This study assessed the use of cervical ultrasonography (US) to select the most suitable animals for transcervical embryo collections. In conclusion, US cervical evaluation allows estimating the number of rings, and the ranking of animals by US cervical misalignment, making possible to select animals suitable for transcervical embryo collection. |
