摘　　要：对应太行肉牛育种实践,综合分析太行肉牛新品种选育的目标性状以及各性状在总性能指数构成中的权重。太行肉牛新品种选育的总性能指数由体型结构、适应性、生长发育、繁殖力、泌乳力及牛肉指数等六大目标性状构成,权重分别为16%、18%、25%、25%、6%和10%。同时描述了各目标性状的具体度量与数据采集方法。以期业界同仁共同探讨、批评指正,合力推进太行肉牛的育种进程。Corresponding to the breeding practice of Taihang beef cattle,this paper comprehensively analyzes the target traits of Taihang beef cattle new breed breeding and the weight of each trait in the total performance index composition.The total performance index of the new breed breeding of Taihang beef cattle consists of six target traits:body structure,adaptability,growth and development,reproductive ability,lactation ability,and beef index,with weights of 16%,18%,25%,25%,6%,and 10%,respectively.At the same time,specific measurement and data collection methods for each target trait were described.In the hope that colleagues in the industry can jointly discuss,criticize and correct,and work together to promote the breeding process of Taihang beef cattle.

关 键 词：肉牛育种 总性能指数 目标性状 数据采集 权重分析。
