Resumen
Descripción
This study compared the efficiency of either transcervical (TC) or surgical (laparotomy; LP) embryo collection in hair sheep. Santa Inês ewes (n = 27) were subjected to a short-term protocol for estrus synchronization and superovulation. Both cervix passage attempt and laparoscopic corpora lutea (CL) count were performed 12 to 24 h before embryo collection. This study demonstrated the overall superior efficiency of TC embryo collection in Brazilian hair sheep.
