摘要
生长曲线的分析和拟合是研究畜禽生长发育规律的主要方法之一,它在实践中可用于生长速率的预测和生长过程的遗传分析。本文对Logistic,Bertanlanffy和Gompertz三种禽类常用生长曲线加以探讨,并以丝羽鸟骨鸡资料为实例进行了分析,结果表明,Logistic模型,Bertanlanffy模型和Gompertz模型对丝羽乌骨鸡的拟合度都很好,其中Gompertz模型在预测早期生长发育方面更具有优越性。
Analysis and fitting of growth curve is an important way when studying the law of growth and development, it has been put practice in prediction of growth rate and genetic analysis of growth process.Logistic model, Bertan-lanffy model and Gompertz model was discussed in this paper. Additionally,the data of Silkies were collected and studied, the results showed that this three models fitted the growth curve exactly and Gompertz model was superior in prediction of early growth and development.
