太平鸡生长规律与生长曲线拟合研究

Study on the growth rule and growth curve fitting of Taiping chicken

为探索太平鸡的生长发育规律,本研究以200羽太平鸡(公母各半)为试验动物,运用Logistic、Gompertz和Bertalanffy三种非线性模型对太平鸡公鸡和母鸡的周龄、体重和生长数据进行生长曲线拟合和分析。结果表明:三种非线性模型都能很好地拟合太平鸡公鸡和母鸡的生长曲线,且拟合度(R 2)均在0.996以上,其中Gompertz模型对太平鸡公鸡和母鸡的拟合效果均最佳,拟合度(R 2)在0.998以上,因此Gompertz模型可作为太平鸡公鸡和母鸡生长曲线拟合的最佳模型。

We explored the growth and development rules of Taiping chickens.In this study,we used 200 Taiping chickens(half male and half female)as research objects,and used Logistic,Gompertz and Bertalanffy models to analyze the growth curve of weekly age weight of male and female Taiping chickens.Results show that all three models could be used for fitting of male and female Taiping chicken growth curve,and fitting(R 2)were above 0.996,among which the Gompertz model was the best for growth curve,and fitting(R 2)was above 0.998.Therefore,the Gompertz model can be used as the best model to fit the growth curve of male and female Taiping chickens.
