【摘要】 通过外源注射各种促性腺激素可促使哺乳动物出现超数排卵现象，这一技术的发展极大地促进了生物技术的进步。目前，超数排卵技术已成熟运用于羊、牛等单胎动物，且已经成功组建了一套相对完善又稳定的操作程序。猪作为多胎动物，早期一直被认为超数排卵的意义不大，对猪超数排卵的研究报道也相对较少。近年来，随着猪胚胎移植、核移植及胚胎冷冻等现代生物技术的不断发展和应用以及生产上后备母猪出现乏情、不发情或发情不明显的现象越来越多，猪超数排卵也得到了越来越多的关注。尤其是小型猪作为异种器官移植供体的最佳选择，其超数排卵相关探究越来越受到学术界的关注。更多还原

【Abstract】 Exogenous injection of various gonadotropins can induce superovulation in mammals.The development of this technology has greatly promoted the progress of biotechnology.At present, superovulation technology has been maturely applied to single-birth animals, such as sheep and cattle, and a relatively complete and stable operating procedure has been successfully established.As a multi-birth animal, pigs have always been considered to have little significance for superovulation in the early days, and there are relatively few reports on superovulation in pigs.In recent years, with the continuous development and application of modern biotechnologies such as porcine embryo transplantation, nuclear transplantation and embryo freezing, as well as the increasing number of estrus, no estrus or unclear estrus in reserve sows in production, superovulation in pigs has also received more and more attention.In particular, as miniature pigs are the best choice for xenotransplantation donors, the research related to superovulation has attracted more and more attention from the academic community.更多还原
