摘　　要：为了了解三黄鸡的生长发育规律,运用Logistic、Gompertz和von Bertalanffy 3种非线性模型分别对三黄鸡1-22周龄体重数据进行了曲线拟合和分析。结果表明：3种模型均能很好地模拟三黄鸡生长曲线,但von Bertalanffy模型拟合效果最佳,运用3种模型对三黄鸡进行生长曲线的拟合和分析是可行的。In order to study the growth and development rules of Three-Yellow chicken,the growth curve of Three-Yellow chicken from 1 to 22 weeks old was analyzed and fitted with three kinds of nonlinear models（Logistic,Gompertz,von Bertalanffy）.The result showed that the growth curves were appropriately fitted with three models,but the von Bertalanffy model had the best effect on fitting with the growth curves.It is feasible to analyze and fit the growth curve of the Three-Yellow chicken using the three models.
