摘要
本研究运用Logistic、Gompertz和Von Bertalanffy3种非线性生长模型对0～12周龄仙居鸡生长发育进行了拟合。研究表明,3种曲线的均能较好的拟合仙居鸡的生长发育过程,拟合度均在0.99以上,但是其中Gompertz拟合结果更符合生产实际,较适用于仙居鸡的生长拟合。通过适宜生长曲线的拟合能够较好地判断掌握鸡群的生长特性,为科学的饲养管理提供可靠的理论依据。
The experiment was conducted to fit and comparative analyses the growth and development of 0-12wk Xianju chicken by three nonlinear growth curves （Logistic,Gompertz and Von Bertalanffy）.The result showed the values of R2 of three curves are all above 0.99,which indicated that all growth curves could appropriately fit the growth and development of Xianju chicken. However the fitting result of Gompertz was more similar with practical production,which was more suitable as the best growth curve for fitting the growth and development of Xianju chicken.It was easy and accurate to judge and control the growth characteristics of chicken by suitable growth curve,supplying the reliable theory for scientific raising and management.
