| 摘 要： | 运用SPSS软件对139只豫西脂尾羊体尺、体重的测定结果进行相关分析和通径分析,并建立最优回归方程。结果表明:豫西脂尾羊的体重(-Y)与体高(X1)、体长(X2)、胸围(X3)、胸宽(X4)、胸深(X5)、尾宽(X6)、尾长(X7)均呈极显著正相关。胸深、体高、胸宽的直接作用和间接作用对体重的影响都极大。得到最优回归方程为-Y=0.438X1+(-0.209)X2+0.554X5;经t检验,方程具有极显著的真实性和拟合度。

| Abstract: | This paper analyzed the correlation between body size and body weight of 139 heads of Yuxi zhiwei sheep by the path analysis and correlation analysis functions of SPSS software,and established the most superior regressive equation.The result showed that the body weight() had extremely significant positive correlation with the body height(X1),body length(X2),chest girth(X3),chest width(X4),chest depth(X5),tail width(X6) and tail length(X7)(p<0.01).The direct action and indirect action of the chest depth,body... |
