摘　　要：定时输精技术综合了同期发情和人工授精技术,对解决生产中母羊发情不集中、非繁殖季节发情率低、常规人工授精受胎率低等问题,以及规模化羊场批次化生产具有重要作用。本文综述了国内绵羊定时输精技术的应用现状,以期为肉羊繁殖技术的应用研究提供参考依据。Timed artificial insemination combines the technologies of synchronized estrus and artificial insemination,which plays an important role in solving the problems of disperse estrus in ewes,low estrus rates in non-reproductive seasons,low fertility rates in conventional artificial insemination,which is of significance for batch production on large-scale sheep farms.This paper summarizes the application status of the timed insemination technology in sheep in China,in order to provide reference for research on the application of mutton sheep reproduction technology.
