摘  要:
[目的]探讨原鸡与不同地方品种家鸡杂交后代的生长发育规律。[方法]以原鸡(♂)与不同地方鸡种(♀)(楚雄麻鸡、茶花鸡、绿耳乌骨鸡、原鸡)杂交组合F1代(♂)为研究对象,测定其0~22周龄的生长发育指标。运用Logistic、Gompertz和Bertalanffy 3种典型的非线性生长曲线模型分别对其进行拟合分析,同时利用逐步回归法建立最优回归方程。[结果]原鸡与不同家鸡杂交F1代(♂)体尺性状对体重影响程度或指标存在一定差异。Logistic和Gompertz模型回归方程的拟合度都达到0.99以上,很好地模拟了原鸡杂交代F1的生长发育规律。[结论]该研究为原鸡遗传资源的保存、利用和地方家鸡品种选育、改良提供了科学依据和参考。

摘  要:
[Objective] The research aimed to discuss the growth and development laws of hybrid offspring from Gallus gallus and different local chicken varieties.[Method] Gallus gallus spadiceus(male) and different Gallus domesticus varieties(female)(Chuxiong Ma Chicken,Chahua Chicken,Green-ear Black-bone Chicken,Gallus gallus) were used as study objects to determine the growth and development indices of 0-22 week-old chicken.Using three typical nonlinear growth curve models(Logistic,Gompertz and Bertalanffy),the growth models of hybrid F1 generation were fit.Meanwhile,the optimal regression equation was established by using stepwise regression method.[Result] The effect degree or indices of the body traits of hybrid F1 generation between Gallus gallus and different local chicken varieties on the body weight had some differences.The fitting degree of the regression equation of Logistic and Gompertz models were both more than 0.99,which better fit the growth and development laws of F1 hybrid generation of Gallus gallus.[Conclusion] This research provided scientific basis and reference for the preservation,utilization of genetic resources of Gallus gallus,and the breeding and improvement of local domestic chicken varieties.
