Abstract: This study evaluated the factors affecting non-surgical embryo transfer (NSET) efficiency in goats. Donor goats (n =10) were superovulated, mated and embryos were collected by non-surgical embryo recovery 7 d after estrous onset. A total of 28 pluriparous recipient goats were subjected to short-term progestagen-based estrous induction protocol with equine chorionic gonadotropin. They received 36 fresh embryos as single (n =20) or in pairs (n =8) by NSET 6?7 d after estrous onset, ipsilateral to the corpora lutea (CL). Pregnancy rate was affected (P <0.05) by embryo stage (blastocyst =63.6 % vs morulae =24.0 %) and quality (Grade 1 =57.1 %; 2 =33.3 %; 3 =10.0 %) and not (P >0.05) by the uterine horn, number of CL (1?3), lactational status and number of embryos transferred per recipient goats. Both overall pregnancy and kidding rates were 32.1 % and 13 kids were born, representing an embryo survival rate of 36.1 %. Goat embryo transfer programs can be successfully performed by using non-surgical techniques, achieving satisfactory embryonic survival rates. |
