| 摘 要： | 运用Gompertz，Logistic，von Bertalanffy 3种非线性模型对0～18周龄的德化黑鸡体重生长数据进行了分析和曲线拟合。结果表明：3种模型均能很好地模拟其生长曲线，拟合度（R^2）高，分别为0．9998、0．9987和0．9996，其中Gompertz模型拟合效果最好。进一步对Gompertz模型拟合参数分析，结果表明德化黑鸡极限体重为1754．7g，拐点体重为815．22g，拐点周龄为8．819周。

| Abstract: | The growth curve of Dehua black chicken from 0 to 18 weeks was fitted with three nonlinear models.The correlation coefficients(R~2) of the chicken's growth data with the Gompertz,Logistic and von Bertalanffy models were 0.9998,0.9987,and 0.9996,respectively.Using the Gompertz model,which had the highest R~2,the maximum applicable adult body weight was found to be 1754.7g,the critical body weight,815.22g,and the critical age of the chicken,8.819 weeks. |
