摘  要：
为研究儋州鸡生长发育规律和各阶段的生长速度,本试验采用Gompertz、Logistic和Bertalanffy 3种非线性模型对黑色羽系和麻花色羽系儋州鸡0～18周龄体重生长数据进行拟合和分析,选取黑色羽系、麻花色羽系儋州鸡各200只(公、母各半),分别于0、2、4、6、8、10、12、14、16和18周龄晨饲前空腹称重并记录,并利用3种非线性模型对儋州鸡生长曲线进行拟合比较分析。结果显示,2种羽色儋州鸡实测生长曲线基本一致,接近于"S"型,符合正常生长发育规律,2种不同羽色儋州鸡母鸡0～18周龄的体重实测值差异不显著(P>0.05),公鸡0～16周龄的体重实测值差异不显著(P>0.05),而16～18周龄麻花色羽系公鸡体重显著高于黑色羽系公鸡(P<0.05)。3种非曲线模型拟合度(R2)均在0.992以上,均能较好地拟合2个羽系儋州鸡的生长曲线,且模型的预测曲线与实际观测曲线基本吻合,但Gompertz模型曲线吻合度高于Logistic和Bertalanffy模型曲线,且母鸡比公鸡拟合效果好。本研究结果初步揭示了儋州鸡的生长发育规律和各阶段的生长特征,可为儋州鸡选育、生产和产业化发展提供科学依据。

摘  要：
In order to explore the growth profiles and growth rates of Danzhou chicken at different stages,three nonlinear analysis models(Gompertz,Logistic and Bertalanffy)were employed to fit and analyze the body weight growth curves of Danzhou chickens with black and mahua colors feather at the age of 0 to 18 weeks.200 Danzhou chickens with black feather(100 males and 100 females)and 200 Danzhou chickens with mahua colors feather(100 males and 100 females)were selected and weighed at 0,2,4,6,8,10,12,14,16 and 18 weeks of age,and the body weight growth curves were fitted and analyzed by Gompertz,Logistic and Bertalanffy models,respectively.The results showed that the growth curve of Danzhou chickens demonstrated a "S"shape,consistent with normal growth and development.The measured body weights of female Danzhou chickens during 0 to 18 weeks and male Danzhou chickens during 0 to 16 weeks showed no significant difference(P>0.05),and that of male Danzhou chickens with mahua colors feather were significantly higher than that with black feather at 16 to 18 weeks(P<0.05).The growth curves predicted by three nonlinear models all fitted well with the measured body weight curves ofDanzhou chickens with black and mahua colors feather(R~2>0.992),and the prediction curve of the model was basically consistent with the actual observation curve.the Gompertz model fitted better than Logistic or Bertalanffy models,and it fitted better in female chickens than male chickens.In summary,the present study revealled the growth profiles and growth rates of Danzhou chicken at different stages,which may provide scientific support for optimizing breeding production and industrialization of Danzhou chicken.
