分析了崇明白山羊和徐淮山羊成年母羊的若干体尺指标与体重的相关性及其直接和间接作用,建立了体重-体尺最优回归模型.结果表明:角基周长可作为预测崇明白山羊成年母羊体重和选择的主要体尺因素,胸深与肩宽则可作为徐淮山羊的相应体尺因素.崇明白山羊成年母羊的体尺-体重最优回归模型为Y=-14.5244+1.9162X_5+0.3862X_4;徐淮山羊的体尺-体重最优回归模型为Y=-47.4653+1.7264X_2+2.0831X_8.
分析瞭崇明白山羊和徐淮山羊成年母羊的若榦體呎指標與體重的相關性及其直接和間接作用,建立瞭體重-體呎最優迴歸模型.結果錶明:角基週長可作為預測崇明白山羊成年母羊體重和選擇的主要體呎因素,胸深與肩寬則可作為徐淮山羊的相應體呎因素.崇明白山羊成年母羊的體呎-體重最優迴歸模型為Y=-14.5244+1.9162X_5+0.3862X_4;徐淮山羊的體呎-體重最優迴歸模型為Y=-47.4653+1.7264X_2+2.0831X_8.

The phenotypic correlations and direct and indirect effects between adult female goats' body weight and several body measurements of Chongming White Goat and Xuhuai Goat were analyzed by the SPSS 16.0 software,and then the optimum regression equations between their body weight and body measurements were established.The results indicated that the horn basal perimeter could be considered as a major factor to predict the adult female goat body weight in the selection of Chongming White Goat,and the chest depth and shoulder width as two major factors in the selection of Xuhuai Goats.The optimal regression model of adult female goats' body measurments and body weight was Y=-14.5244+1.9162X_5+0.3862X_4 for Chongming White Goat and Y=-47.4653+1.7264X_2+2.0831X_8 for Xuhuai Goat.
