| 摘 要： | 用Logistic模型和Compertz模型分别拟合了180只陶寒杂种羊生长发育规律,其中以Compertz模型拟合的R2较大.用Compertz模型参数进一步估算出公羊和母羊的最大体质量分别为25.87 kg和22.64 kg,最大月增质量分别为4.23 kg和3.68 kg,拐点月龄分别为1.98月和2.43月,拐点体质量分别为12.94 kg和11.32 kg,瞬时相对增长率分别为44.35%和44.11%.

| Abstract: | Compertz model with the maximum R2 between two nonlinear model(Logistic model and Compertz model) was used to fit filial-generation(Poll Dorset×Small-tailed Han sheep) growth curve.Meanwhile,the parameters of growth model were obtained.The maximum body weight was 25.87 kg for bucks and 22.64 kg for does,maximum month weight was 4.229 kg for bucks and 3.681 kg for does,spinodal age was 1.979 months for bucks and 2.426 months for does,spinodal weight was 12.94 kg for bucks and 11.32 kg for does,constant growth rate was 0.4435 for bucks and 0.4411 for does,respectively. |
