摘要: 通过评价双胚胎移植方法和单胚胎移植方法对蒙古绒山羊妊娠率及产羔率的影响,为优质种羊的快速扩繁提供技术支持。选取5只供体母羊进行同期发情与超数排卵处理,供体母羊发情后进行人工授精,收集胚胎;利用收集的可用胚胎对选取的39只受体母羊进行胚胎移植,其中10只受体母羊做双胚移植,29只受体母羊做单胚移植;比较双胚移植和单胚移植受体母羊的妊娠率及产羔率。结果表明:供体母羊经CIDR处理,发情率达100%,超数排卵、人工授精后共收集胚胎64枚,其中可用胚胎49枚,可用胚胎率为76.56%;双胚移植受体母羊的妊娠率为90.00%(9/10),产羔率为180.00%(18/10),单胚移植受体母羊的妊娠率为68.97%(20/29),产羔率为62.07%(18/29)。双胚移植方法比单胚移植方法可获得更高的妊娠率及产羔率,表明双胚移植方法适用性良好,具有极大的推广价值。

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.
