摘 要:本文对京海黄鸡配套系亲本父系(F)与如皋黄鸡杂交(T)测定后进行Logistic、Gompertz与Von Bertallanffy 3种模型曲线的拟合研究,结果表明:组合FT母鸡和公鸡料肉比在0~10周龄前均为持续增长状态,在2~6周龄增加迅速,6周龄后增量略微减少。同一周龄公鸡的料肉比低于母鸡。组合FT鸡成活率较高。Gompertz模型的拟合效果最好。运用Gompertz模型拟合的组合FT母鸡曲线模型的拟合度为0.999,拐点体重为850.67g,拐点周龄为6.19周。公鸡曲线模型的拟合度为1.000,拐点体重为1709.14g,拐点周龄为9.19周。In this paper, after the hybrid performance measurement of parental paternal in Jinghai yellow chicken lines(F) and Rugao yellow chicken(T) of fitting study Logistic, Gompertz and Von Bertallanffy 3 kinds of model curves.The results showed that : The growth state of the FT hen and the rooster ' s feed meat ratio in the 0 ~10 week age were increased rapidly, and the increase of the 2 ~6 weeks age increased rapidly,after 6 weeks the increment decreased slightly,The feed meat ratio of the same week old cock is lower than the hen. The survival rate of FT hybrid combination was high. Gompertz model is best.The Gompertz curve of FT hybrid combination of female hybrid offspring ' s fitting degree was 0.999,inflection point weight was 850.67 g,inflection point age was6.19 weeks While the male hybrid offsetting fitting degree,inflection point weight,inflection point week was 1.000,1 709.14 g,9.19 weeks.
