摘　　要：繁殖性状是繁殖周期内发生繁殖事件相关性状的集合,是由多个部分组成的复杂性状.繁殖性状表型鉴定对挖掘与繁殖力密切相关的分子标记,解析“表型-基因型-环境型”内在关系,揭示优异繁殖性状形成机理具有重要作用,也是动物繁殖性能选育提高和动物平衡育种的基础和关键.基于此,本文综述了反刍动物繁殖性状主要表型鉴定的内容与方法,讨论了反刍动物繁殖性状表型鉴定的发展趋势,以期为合理选用和改进动物繁殖性状表型鉴定方法提供参考,也为提高反刍动物繁殖性状的选择效率和遗传进展提供支撑.Reproductive traits are a collection of complex traits associated with reproductive events that occur during the reproductive cycle andcomprise multiple parts. The phenotypic identifications of reproductive traits are critical for identifying the molecular markers closelyrelated to fecundity, analyzing the intrinsic correlation between the “phenotype-genotype-environment type,” revealing themechanisms underlying the formation of excellent reproductive traits, and improving animal breeding for reproductive performanceand balanced breeding. Therefore, this paper reviews the methods and developmental trends in the phenotypic identifications of theprimary reproductive traits of ruminants. This will not only provide a reference for improving the level of phenotypic identifications,but also provide materials and supporting information to improve the selection efficiency and genetic progress of the reproductivetraits in ruminants.
