| 摘 要： | 采用SAS软件CORR过程对重庆黑山羊成年羊体尺体重指标与胴体净肉率进行相关分析，并以成年体高X1、体斜长X2、胸围X3、胸宽）（4、胸深X5、成年体重X6为自变量，胴体净肉率Y为因变量，采用REG过程BACKwARD（后退法）的多元回归分析方法，构建了估测重庆黑山羊胴体净肉率的最优回归方程：Y=9．9370—0．0109X3—0．2184X4＋0．4914X5。

| Abstract: | The phenotype correlation between body size body weight and carcass net muscle percentage of Chongqing Black Goat were analyed with SAS software CORR progress. With carcass net muscle percentage Y as dependent variables, body height (X1), trunk length (X2), chest girth (X3), chest width (X4), chest depth(X5), body weight(X6) as independent variables, REG progress BACKWARD multiple regression analysis was carried out.And the optimum regression equation was established subsequently: Y =69.9370 -0.0109X3 -0.21... |
