【摘要】 对福建兔(黄毛品系)0～240日龄生长曲线进行了分析和非线性曲线拟合研究。结果表明:福建兔(黄毛品系)在30 日龄前生长曲线较一致,之后公兔明显快于母兔。Logistic、Bertalanffy和Gompertz模型均能很好地拟合福建兔(黄毛品系)的生长曲线(R2均大于0．98)。其中Bertalanffy模型在拟合度和预测体重效果方面最好,其公母兔生长模型分别为:公兔(g):W= 3841 ×(1-0．76×e-0．82)3;母兔(g):W=3571×(1-0．74×e-0．8)3。更多还原

【Abstract】 The growth of curves of Fujian rabbits( yellow line)of 240 days old were analyzed and fitted with three kinds of non- linear models. The results indicated that the males and females had the same growth curve before 30 days old. And then, the males got a higher growth rate than females did. The growth curves could be fitted by Logistic model, Bertalanffy model and Compertz model for males and females. But Bertalanffy model was considered to be the best model to fit growth curves of Fujian rabbits, because of its higher fitness and less bias of predicted body weight on the given age. the growth model for the males and females are: the males (g):W= 3841 × (1-0.76× e-0.82)3,the females(g) :W = 3571 × (1-0.74× e-0.8)3.更多还原
