摘　　要：本研究收集了北京、宁夏地区41343头荷斯坦牛产犊、离群、体型鉴定等数据进行分析,旨在研究荷斯坦牛生产寿命与体型性状之间的关系。研究利用产犊、离群记录计算得到了生产寿命数据,根据体型性状数据运用动物模型计算育种值,将生产寿命数据划分为12个水平,采用了Bonferroni法进行多重检验,分析了体型性状在不同生产寿命分组中的差异。结果显示,与泌乳系统相关的体型性状如中央悬韧带、前乳房附着、前乳房、泌乳系统总分,在不同生产寿命分组中差异较明显;与运动相关的体型性状如肢蹄、与体躯大小相关的体型性状如体高,以及体型总分在不同生产寿命分组中差异均较明显。本研究初步分析了生产寿命与体型性状之间的关系,为生产寿命在奶牛育种中的研究和辅助选育提供参考。This study collected and analyzed the data of 41343 Holstein cows in Beijing,Ningxia areas,such as calving,outlier and body shape identification,in order to study the relationship between production life(PL)and body shape traits of Holstein cows.In this study,calving and outlier records were used to calculate the PL trait.Secondly,animal model was used to calculate the EBV according to the body shape data.Finally,according to the PL trait data,it was divided into 12 levels.Bonferroni method was used for multiple tests,and the differences of body shape in different PL groups were analyzed.The results showed that the traits related to lactation system,such as Median_suspensory,Fore_attachment,Fore_under and the Mammary_system,were significantly different in different PL groups.There are obvious differences in body shape traits related to sports,such as Feet_legs,body shape traits related to body size,such as Stature,and the Conformation among different groups of PL.This study preliminarily analyzed the relationship between PL and body shape traits,and provided reference for the research of PL in dairy cattle breeding and auxiliary breeding.
