摘　　要：以辽宁省两个复州牛保种场104头母牛2004年体尺数据为基础材料,对复州牛体重与年龄、体长、体高、胸围、管围的相关系数进行了分析,同时建立了估测复州牛成年母牛体重的回归模型。结果表明:复州牛体重与体高、体长、胸围、管围、年龄之间的相关系数分别为0．798、0．644、0．678、—0．167、0．406,经检验,除管围与体重的相关系数不显著外(P＞0．05),其它四个相关系数均达到极显著水平(P＜0．01);两个估测体重的回归模型估测值与实测值之间的相关程度分别为0．923和0．922,达到极显著水平(P＜0．01)。Based on the measurements of 104 cows of Fuzhou cattle in two conservation farms of Liaoning province in 2004, the correlations between body weight and age as well as body sizes including body length, body height, heart girth, and cannon circumference were analyzed, meanwhile the regression equation was established to predict the body weight of cows. The correlation coefficients of body weight with body height, body length, heart girth, cannon circumference, and ages were 0. 798, 0. 644, 0. 678, -0. 167, and 0. 406, respectively, all correlations were significant （P〈0. 01） except that between body weight and cannon circumference. The correlation coefficient of predicted and measured values from two regression equations were 0. 923 and 0. 922 （P〈0.01）, respectively.
