| 摘 要： | 本试验运用Log-Logistic、Gompertz和Von Bertalanffy三种非线性生长发育曲线模型对南疆绒山羊的早期生长发育进行拟合研究。结果表明：三种模型中Log-Logistic模型对南疆绒山羊早期生长发育的拟合效果和预测体重方面效果最佳。分析计算Logistic模型拟合参数，发现拐点体重为8.43 kg，拐点月龄为1.878月。结论：根据Log-Logistic模型建立了南江黄羊的早期体重生长曲线，在拐点月龄（1.878月）以前，必须加强对妊娠母羊的饲养管理、提高营养水平，促进南疆绒山羊羔羊体重最大化提高。

| Abstract: | The paper fittingly studies early growth and development of Nanjiang cashmere goat by three nonlinear curve models (Log-Logistic, Gompertz and Von Bertalanffy). The results indicates that:Log-Logistic is best in imitative effect and weight prediction. It is found weight inflexion is 8.43 kg and months of age inflexion is 1.878 months. So we come to the following conclusions:the early weight growth curve of the Goat is built based on the model of Log-Logistic, and we must enhance feeding management and improve nutrient to maximize the weight of the Goat before months of age inflexion(1.878 months). |
