摘要
本研究用Logistic、Gompertz和Bertallanffy 3种非线性生长模型对文昌鸡母鸡的生长发育进行拟合。研究结果表明,3种模型均能较好地拟合文昌鸡生长曲线,但是Gompertz模型拟合效果最佳。运用3种模型对文昌鸡进行生长曲线的拟合和分析是可行的,对及时掌握文昌鸡的生长发育规律提供了参考。
The objective was to study the growth and development rules of Wenchang chicken. The arowth curve of Wenchang chicken from 0 to 18 weeks age was analyzed and fitted with three kinds of nonlinear models （Gompertz,Logistic,von Bertalanffy）. The growth curves were appropriately fitted with three models, but the Gompertz model had the best effect on fitting with the growth curve.It is feasible to analyze and fit the growth curve of the Wenchang chicken using the three models.
