中文摘要：【目的】了解快羽和慢羽麒麟鸡生长发育规律,评估其作为培育自别雌雄配套系遗传素材的价值,挖掘并利用该地方遗传资源。【方法】分别采用Bertalanffy、Gompertz和Logistic 3种模型拟合分析麒麟鸡快羽系和慢羽系1~19周龄生长发育规律,探究其合适的生长模型。【结果】对于公鸡,快羽和慢羽公鸡体重仅在第1周龄差异显著(0.01

外文摘要：【Objective】This study was conducted to uncover the development of Kirin chicken with slow or fast feather,to evaluate if Kirin chicken could be used in breeding sex-identification set line and excavate and utilize the local genetic resources.【Method】Bertalanffy,Gompertz and Logistic models were used to analyze the growth patterns of fast and slow feathered line of the Kirin chicken from the age of 1 to19 weeks and explore the suitable growth model.【Result】For the males,the body weight was significantly different between fast and slow feathered chicken at the 1stweek(0.01rd week(P<0.01),but the results were opposite at the 7thweek(P<0.01).At the remaining time point,there were no significant differences.The keel bone length tended to be consistent in different strains including roosters and hens,but the shank length and circumference showed different at various periods.The fitness of the 3models for body weight was very high(R^(2)≥0.985),among which the best one was Bernalanffy model.The fitness(R^(2))of the fast-feathered rooster and hen was 0.999 and 0.993,respectively,while the fitness(R^(2))was 0.994 for the slow feathered rooster and hens.The best fitted model for keel bone length and shank circumference was the Bertalanffy for the two types of feathered Kirin chicken.While Logistic was the best model for the shank length of the fast-feathered chicken and Gompertz was the optimal model for the shank length of the slow-feathered chicken.【Conclusion】There were differences existed between the two lines of Kirin chicken during their growth and development.The Bertalanffy model was the best for body weight,keel bone length and shank circumference,respectively,while Logistic and Gompertz were optimal for the shank length of the fast and slow feathered Kirin chicken.In production practice,the optimal feeding conditions should be provided at different stages to meet the nutritional requirements of chickens during their growth and development.
