不同性别龙胜凤鸡生长曲线的拟合与分析

摘要

为了解龙胜凤鸡的生长发育规律，本研究运用Logistic、Gompertz和Bertalanffy3种非线性模型分别对龙胜凤鸡的生长情况进行曲线拟合和分析。研究结果表明，3种模型均能较好的模拟龙胜凤鸡生长曲线，拟合度假。）均高于0．99，其中以Bertalanffy模型的拟合度最高（公、母鸡都为0．997）。因此，运用3种模型对龙胜凤鸡进行生长曲线的拟合和比较分析是可行的，本研究也为及时了解龙胜凤鸡的生长发育规律提供了参考。%In order to research the growth curve of Longsheng linear models,such as Logistic,Gompertz and Bertalanffy,were used results show that the growth curves were appropriately fitted with the values of R2 were more than analyze Chicken 0.99,and Bertalanffy models fi g Chicken,three non- alyze and fit it. Our the three t most. non-linear models, So,it is feasible to and fit the growth curve of the different gender growth curve of Longsheng Feng using these non-linear models
