Abstract: In order to provide technical support for the rapid propagation of good quality breeding Cashmere Goat, the effect of embryo transfer methods with dual embryos and single embryo on pregnancy rate and lambing rate of Mongolian Cashmere Goats was evaluated. Five donors were subjected to estrus synchronization and super-ovulation and were then artificially inseminated. The collected available embryos were transferred into 39 receptors, 10 of them received dual embryos and 29 of them received single embryo. The pregnancy rate and lambing rate of dual embryos and single embryo transferred receptors was calculated and compared. The results showed that the estrus rate of the 5 donors treated by CIDR was 100%; a total of 64 embryos were obtained and 49 of them were qualified to be used for embryo transfer, indicating the available embryo rate was 76.56%, the pregnancy rate and lambing rate of receptors receiving dual embryos was 90.00% (9/10) and 180% (18/10), respectively; the pregnancy rate and lambing rate of receptors receiving single was 68.97% (20/29) and 62.07% (18/29) , respectively. Dual embryos transfer method showed higher pregnancy rate and lambing rate than single embryo transfer method and had good applicability and great extension value.
