| 摘 要： | 为了解桂香鸡母鸡的生长发育规律，采用Logistic、Gompertz和Bertalanffy3种非线性模型，分别对桂香鸡母鸡1～16周龄体重增长情况进行了拟合与分析。试验结果表明，3种模型的拟合度均达到了0．981以上，其中，Bertalanffy模型拟合效果最好，拟合度为0．993，该模型预测的桂香鸡母鸡拐点周龄为4．55周，拐点体重为333．10g。该研究揭示了桂香鸡的生长发育规律，同时为桂香鸡的生产管理和育种提供了参考依据。

| Abstract: | In order to understand the growth law of Guixiang hens, three non-linear models （Logistic, Gompertz, and Bertalanffy） were adopted in this study to fit and analyze the body weight growth of Guixiang hens at the age of 1 -16 weeks. The results showed that the fitting degree of the three models all reached up to 0.981; the best fitting effect was observed in Bertalanffy model and the fitting degree was 0.993; using Bertalanffy model, the growth inflexion of Guixiang hens was 4.55 weeks and the inflection point weight was 333.10 g. Our results revealed the growth law of Guixiang chicken and offered a reference basis for the production and breeding of Guixiang chicken. |
