河北柴鸡1～16周龄生长曲线分析与拟合的比较研究

Comparative study on the analysis and fitting of growth curves of 1～16 weeks Hebei local chicken

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VonBertalanffy模型都能很好地拟合河北柴鸡的生长曲线(R2分别为0.99598、0.99837和0.99809),其中Gompertz模型在拟合度和预测体重效果方面最好。

The growth curves of Hebei domestic chickens from 1 to 16 weeks old were analyzed and fitted with three kinds of non-linear models.The results indicated that the growth curves could be fitted very well with Logistic model,Gompertz model and Von Bertalanffy model(R2 = 0.99598,0.99837,0.99809).Gompertz model was the best in fitting and predicting body weigh.
