摘  要:
为了提高测定效率,运用SPSS软件对30只赛加羚羊初生羔的体尺、体重结果进行了相关分析和通径分析,并建立了最优回归方程。结果表明:赛加羚羊初生体重(Y)与体直长(X_1)、体高(X_2)、胸深(X_3)、胸宽(X_4)、胸围(X_5)、尾长(X_6)、耳长(X_7)及管围(X_8)均呈极显著正相关(P<0.01),其中体直长(X_1)和胸围(X_5)是体重(Y)的最主要决定变量。初生羔羊体直长(X_1)和胸围(X_5)对体重(Y)的最优回归方程为Y=-1.219+0.052X1+0.072X5。

摘  要:
In order to improve the measurement efficiency,this paper analyzed the correlation between body size and body weight of 30 heads of Saiga tatarica 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(Y) had extremely significant positive correlation with the body length(X_1),body height(X_2),chest depth(X_3),chest width(X_4),chest girth(X_5),tail length(X_6),ear length(X_7) and cannon circumference(X_8)(P<0.01).The direct action of the chest girth and body length were the decision variable on body weights.The most superior regressive equation was:Y =-1.219+0.052X_1+0.072X_5.
