摘　　要：采用Logistic、Von Bertalanffy和Gompertz 3种典型非线性生长模型分别对渝东白山羊与波尔山羊F，0-6月龄体重数据进行曲线拟合分析。结果表明，Logistic、Von Bertalanffy和Gompertz3种模型均能很好地拟合杂交F．生长曲线，但VonBertalanffy在拟合效果和预测体重效果方面更佳。分析Yon Bertalanffy模型拟合参数，发现拐点体重为6．501kg，拐点月龄为1．292月，最大月增重为2．955kg，成熟体重为21．994kg。Data of body weight from Yudong White x Boer crossbred F lanffy and Gompertz models. The results indicated that Logistic, Von Be were curve fitted using nonlinear Logistic, Von Berta- rtalanffy and Gompertz models could fit growth curve of crossbred F1 well. But Von Bertalanffy model was the best.The parameters turning point of body weight was 6.501kg;the turning point of age was 1.292 kg and the adult body weight was 21.994kg. from Von Bertalanffy model demonstrated that the month; the maximal monthly weight gain was 2.955
