摘要
应用通径分析理论,对48只多浪羊羔羊断奶体重与体尺性状指标进行了相关分析,且对体重效应作用大小,即决定系数进行了分析。其结果表明:多浪羊羔羊断奶体重与体尺性状有极显著相关性(P<0.05),对体重影响其决定作用的是胸围,其次是体长和胸深,这在羔羊断奶选种时值得重视。多浪羊羔羊断奶时其体尺性状与体重的最优回归模式为Y=-35.11+0.2X_1+0.551X_3+0.
The paper probed into the correlation between body size and weaning weight of 48 lamb of duolang,based on path analysis.The result showed that body size had significantly correlation with weaning weight （P〈0.05）,the decisive character of DuoLang lamp＇weaning weight was its chest girth,the second factor was the pertinence of its chest depth and body length,the result could be used as a reference information for selection and breeding lamb of DuoLang when ablactation.The optimization regression equation was Y =- 35.11 ＋0.2X1＋0.551 X3＋0.619X4.
