摘要: 江汉鸡是湖北省优良的地方鸡品种,为了解其早期生长发育规律,为其品系选育提供参考依据,本研究运用Logistic、Gompertz和Von Bertalanffy三种非线性生长模型对江汉鸡0~20周龄体重生长情况进行曲线拟合和分析。结果表明三种曲线均能较好地拟合江汉鸡的生长曲线,经分析比较发现,Gompertz模型拟合的江汉鸡生长曲线效果最佳(R2≥0.996),其公鸡的拐点为(9.170周,763.070 g),母鸡的拐点为(9.355周, 623.185 g)。三种模型对江汉鸡生长曲线的拟合和分析是可行的,通过生长曲线的拟合分析可及时掌握江汉鸡的生长发育规律、发现饲养管理中存在的问题。

Abstract: Jianghan chicken is a good local chicken of Hubei. The study of early growth rules of Jianghan chicken provide an evidence for new lines breeding. Three kinds of nonlinear model (Logistic, Gompertz and Von Bertalanffy) were used to analyze the growth curve of Jianghan chicken from 0 to 20 weeks. The results showed that the growth curves were appropriately fitted with the three models. Compared the three fitted results, the Gompertz model had the best effect on fitting with the growth curves of Jianghan chicken (R2≥0.996), the growth inflexion was 9.170 weeks and 763.070 g for male chicken and 9.355 weeks and 623.185 g for female chicken. It was feasible to analyze and fit the growth curve of the Jianghan chicken using the three models. Through the fitting of the growth curve, we can master the growth and development patterns of Jianghan chicken in time and find the problems in feeding and management.

Key words: Jianghan chicken, weight, growth curve, nonlinear model
