| 摘 要： | 应用直线相关、通径分析及偏回归分析方法，研究７个体躯结构性状与胸围的线性关系．结果表明：上述关系的程度因性别而异，且随年龄变化而变化．公牦牛随年龄增长而加深，母牦牛随年龄增长而减弱．对胸围进行间接选择应重视的性状因年龄、性别的不同而有所区别

| Abstract: | The corelation between 7 body formation traits and heart girth of Jiulong yak are analysed by using the mathods of linear corelation,path way analysis and bias corelation.The corelation coefficiencies are dependent on sex and age.The coefficiency becomes greater with the increase of age in male yak,but it becomes smaller with the increase of age in female yak.Therefore,the effect of sex and age should be recognized when heart girth is used for indirect selection. |
