摘　　要：为了解乌蒙凤鸡的生长发育规律,本研究以Logistic和Gompertz 2种非线性生长模型对乌蒙凤鸡体重及胫长进行拟合分析。结果表明:Gompertz模型在估计乌蒙凤鸡母鸡体重生长规律上效果更优,该模型拐点周龄为3.49周,拐点体重为753.84 g;Logistic模型在拟合乌蒙凤鸡胫长方面效果更优,拐点周龄为2.32周,拐点胫长为4.26 cm。这说明即使对同一品种的不同性状,其适用的最优模型也存在差别。In order to investigate the rules of growing and developping about Wumengfeng chicken,the study analysis the body weight and shank length of wumengfeng chicken by Logistic models and Gompertz models.The results showed that Gompertz model was better than Logistic models in estimating Wumengfeng chicken’body weight,and inflection date was the first 3.49 weeks,and inflection weight was 753.84 g.However,Logistic model was better than Gompertz models in estimating Wumengfeng chicken’body shank length,and inflection date was the first 2.32 weeks,inflection shank length was 4.26 cm.The results were various for adopting the different indicators.
