| 摘 要： | 对0～9周龄的连城白鸭肉用新品系早期生长发育情况进行了测定和分析,并运用Gompertz模型对其生长曲线进行拟合与分析。结果表明:Gompertz模型能很好地模拟连城白鸭肉用新品系生长曲线,拟合度(R2)高(公鸭:R2=0.9998,母鸭:R2=0.9997),进一步对拟合参数分析,发现连城白鸭肉用新品系公鸭极限体重为2423.6g,拐点体重为891.7g,拐点周龄为3.5周;母鸭极限体重为2099.2g,拐点体重为772.3g,拐点周龄为3.2周。

| Abstract: | Early growth of meat new line of liancheng white duck from 0 to 9 weeks old was measured and analyzed,and the growth curve was fitted with Gompertz model in this study.The result showed that the growth curve could be well fitted with Gompertz model and the R2 was high(R2=0.9998,0.9987,0.9996).Analyzing the fitting parameters of the Gompertz,we found the adult body weight of male duck was 2 423.6 g,body weight at the point of inflexion was 891.7 g,age at the point of inflexion was 3.5 weeks and the adult bod... |
