摘    要:本研究运用Gompertz, Logistic, von Bertalanffy三种非线性模型对饲养在青藏高原的藏母鸡和藏公鸡0至16周龄体重生长数据进行了曲线拟合和分析。研究结果表明:三种模型均能很好的模拟藏鸡生长曲线,但Gompertz模型拟合效果更佳;进一步分析Gompertz模型拟合参数,发现藏公鸡成年体重(1252.0g)显著高于藏母鸡(808.9g),但藏公鸡的拐点时间为13.20周较藏母鸡的拐点时间11.27周迟。

关 键 词:生长曲线  藏鸡  体重  模型

Abstract:The growth curve of Tibetan chicken from 0 to 16 weeks old was analyzed and fitted with three kinds of nonlinear models (Gompertz, Logistic, von Bertalanffy).The result showed that the growth curves could be well fitted with three models, but the Gompertz model had the best effect on fitting with the growth curves. Analyzing the fitting parameters of the Gompertz, we found the adult body weight of cock is higher than the hen notably, but the growth inflexion of cock (13.20 weeks) is late to the hen (11.27 weeks).
Keywords:Growth curve  Tibetan chicken  Body weight  Model
