摘　　要：为了解塞北乌骨鸡的生长发育规律,运用Bertallanffy、Gompertz和Logistic三种非线性模型分别对塞北乌骨公、母鸡1～14周龄的体重进行生长曲线拟合与分析。结果表明,三种模型均能较好地拟合塞北乌骨鸡生长曲线,拟合度均达到0.992以上,其中Logistic拟合效果最好。The objective was to study the growth and development rules of saibei silky.The growth curve of Saibei silkies from 1 to 14 weeks old was analyzed and fitted with 3 non-linear models of Bertallanffy, Gompertz and Logistic.The results showed that：the growth curves could be fitted well with three models and degrees of fitting were more than 0.992, and the fitting degree of Logistic was the highest of all.
