Resumen
Descripción
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.
