摘要
试验旨在通过生长曲线的拟合来了解文昌鸡生长发育的规律。用Logistic、Gompertz和Bertallanffy 3种非线性生长模型对公母文昌鸡的生长发育进行拟合。3种模型均能较好地拟合文昌鸡生长曲线,但是Gompertz模型在公母鸡上拟合效果均最佳。公母鸡在4周前生长较一致,4周后,公鸡生长速度明显快于母鸡。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,对及时了解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.Three nonlinear curves of Logistic,Gompertz and Bertallanffy model were used to fit the growth model in Wenchang chicken of both sex.The results indicated that the growth curves were appropriately fitted with three models,but the Gompertz model had the best effect on fitting with the growth curves.The Wenchang cock and hen grew approximately consistent before the age of 4 weeks,but cock grew faster than hen after the age of 4 weeks. It is feasible to analyze and fit the growth curve of the Wenchang chicken using the three models.
