摘 要:为探讨郏县红牛成年母牛体尺指标与体重的相关性,运用SPSS 26.0软件对47头郏县红牛成年母牛体尺指标、体重的测定结果进行相关分析和通径分析,并建立了最优回归方程。结果表明:郏县红牛的体重(Y)与体高(X 1)、体长(X 2)、胸围(X 3)、坐骨端宽(X 4)、管围(X 5)呈极显著正相关(P<0.01);胸围、体长、坐骨端宽对体重的直接影响较大,而管围、体长、坐骨端宽对体重的间接影响较大。构建的最优回归方程为=-739.750+1.859X 2+4.158X 3+5.559X 4。In order to investigate the correlation between body size indices and body weight of adult cows of Jiaxian Red Cattle,the correlation analysis and path analysis were carried out on the determination results of body size indices and body weight of 47 adult cows of Jiaxian Red Cattle by using SPSS 26.0 software.And the optimal regression equation was established.The results showed that body weight(Y)was positively correlated with body height(X 1),body length(X 2),chest circumference(X 3),hucklebone width(X 4),and circumference of cannon bone(X 5)(P<0.01).The chest circumference,body length and hucklebone width had greater direct effects on the body weight,and circumference of cannon bone,body length and hucklebone width had greater indirect effects on the body weight.The optimal regression equation constructed was=-739.750+1.859X 2+4.158X 3+5.559X 4.
