| 摘 要： | 对河北柴鸡1-16周龄生长曲线进行了分析和非线性曲线拟合研究。结果表明，Logistic模型、Gompertz模型和Von Bertalanffy模型都能很好地拟合河北柴鸡的生长曲线(R^2分别为0．99598、0．99837和0．99809)，但Gompertz模型在拟合度和预测体重效果方面相对较好。

| Abstract: | The growth curves of Hebei Domestic Chickens from 1 week-old to 16 week-old were analyzed and fitted with three kinds of non-lineared models. The results indicated that the growth curves could be fitted very well by Logistic model,Gompertz model and Von Bertalanffy model(R2=0.99598,0.99837 and 0.99809,resp.).Gompertz model was better in fitting and predicting body weight. |
