摘  要:
通过 3个优质地方鸡种之间的杂交 ,对一级杂交 6个组合繁殖性能进行了测试。按入舍母鸡产蛋量计 ,由高到低依次为LC >SC >CL >LS >CS >SL ,差异较小。至于在肉鸡繁育体系中哪些组合可供配套使用 ,还受到二级杂交商品肉鸡早期增重和饲料报酬等经济指标及其它因素的制约 ,最终取决于单交母本与第二父本的配合力。

摘  要:
In the study, three breeds of superior indigenous broilers were crossbred with one another, and the six combinations from the first step cross breeding were tested for their performance. There is no significant difference in hen housed egg production between these combinations,but there is a numerical trend that LC>SC>CL>LS>CS>SL. Which combinations can be used in the cross breeding system is also determined by some economic merits of the second step cross breeding combinations such as the early weight gain and feed conversion, and is finally determined by the combining ability of the dam in the first step cross breeding and the sire in the second step cross breeding.
