| 摘 要： | 运用Logistic、Gompertz和Bertallanffy 3种被广泛采用的非线性生长模型,对苏禽乌骨鸡的累计产蛋数进行拟合分析.结果表明,3种模型都能很好地对其累计产蛋数进行拟合,拟合度(R2)都在0.99以上,尤其以Bertallanffy模型对苏禽鸟骨鸡的累计产蛋数拟合效果最佳,其拟合的拐点周龄和拐点产蛋数...

| Abstract: | The egg production curve of Suqin Silkies fed from 160 to 400 days was analyzed and fitted with three kinds of non-linear models(Gompertz,Logistic,Bertalanffy).The results showed that the egg production curves were appropriately fitted with all the three models.The values of R2 were higher than 0.99 and the Bertalanffy model represented the best fitness on predicting egg production and inflection time.Analysis of the fitting parameters of the Bertalanffy showed that the inflection egg production of Suqin Si... |
