【摘要】 胚胎移植是指将雌性哺乳动物体内或体外获得的早期胚胎移植到同种、生理条件一致的受体雌性动物的生殖道内，使之继续发育，最后生长为正常个体的繁殖技术。该项技术在动物繁殖学、动物遗传学和动物育种学等领域得到广泛应用，尤其对于马这种繁殖能力不强的动物，采用胚胎移植技术可以提高其妊娠率及产驹率。马胚胎移植的整个过程包括供体母马与受体母马的选择、供体母马与受体母马的同期发情、供体母马的超数排卵与配种及胚胎的回收、质量鉴定、保存和移植等环节，且各个环节对马胚胎移植成功率均有重要影响。本文主要对马胚胎移植的关键环节进行总结，以期为马繁殖等相关问题的深入探索提供参考依据。更多还原

【Abstract】 Embryo transfer refers to the reproductive technology that transfers the early embryos obtained in vivo or in vitro of female mammals to the reproductive tract of the recipient female livestock with the same physiological conditions, and the embryos continue to develop and finally grow into normal individuals.Therefore, this technology has been widely used in animal reproduction, animal genetics and animal breeding, especially for animals with poor reproductive ability such as horses, which will increase their pregnancy rate and foal birth rate. The whole process of horse embryo transfer includes the selection of donor mare and recipient mare, the simultaneous estrus of donor mare and recipient mare, the superovulation and mating of donor mare, the recovery of embryos, the quality identification of embryos, the preservation of embryos and the transfer of embryos, and all aspects affecting the success rate of horse embryo transfer. Therefore, this paper mainly summarized the key links of horse embryo transfer, in order to provide some reference for the in-depth exploration of horse breeding and other related issues.更多还原
