Abstract: 【Objective】 Multiple ovulation and embryo transfer (MOET) technology is an important technique for obtaining excellent germplasm resources, but many factors affect embryo survival and pregnancy, and a large amount of data is needed to support it. The purpose of this study is to investigate the influence of embryonic and receptor factors on survival after embryo transfer.【Method】A retrospective survey about embryonic and recipient factors on the survival rate of transferred embryo was done in our application in mutton sheep.【Result】These results showed that the remote transition of donor, recipient and fresh embryo were adverse to gestation than on site transition (P<0.01). There was no significant difference on pregnancy between embryonic cleavage and blastocyst stage(P>0.05), but the rate of pregnancy with two cell transplantation on the embryonic cleavage stage was the lowest. And it was the same to embryo survival and recipient pregnancy rates after transfer of the fresh and vitrified in vitro produced ovine blastocysts (P>0.05). The pregnancy rate of 2 embryos was higher than that of 1 embryo. The rate of embryo pregnancy decreased with the quality of embryo. The recipient pregnancy rate was not be affected by the blastocysts earlier than the synchronizing recipient on 24 hours after embryonic transfer (P>0.05). There was no significant difference in the receptor pregnancy rate between the grazing and feeding sheep embryos (P>0.05).【Conclusion】These results confirm that both embryonic and recipient factors play an important role in the success after embryo transfer in sheep.

摘要: 【目的】胚胎移植技术是获得优秀种质资源的一种重要应用技术,研究影响胚胎存活和妊娠的因素。【方法】回顾性调查分析影响胚胎移植后成活的胚胎和受体因素。【结果】三种胚胎运输方式的妊娠率极显著低于就近移植的妊娠率(P<0.01);胚胎卵裂期与囊胚期移植妊娠率差异不显著(P>0.05),但以 2 细胞移植的妊娠率最低;鲜胚与冻胚的妊娠率差异不显著(P>0.05),2 枚胚胎的妊娠率高于1枚胚胎的妊娠率,胚胎妊娠率随着胚胎质量而下降;囊胚与受体同期性差-24 h,妊娠率差异不显著(P>0.05);放牧与舍饲的受体羊在胚胎妊娠率方面没有显著差异性(P>0.05)。【结论】胚胎和受体因素对胚胎发生成功妊娠具有重要的影响。
