摘要
地方鸡种如皋黄鸡的C3品系拥有良好的产蛋性能,但其蛋重较小、淘汰母鸡体重较轻,因此有必要利用体型较大的地方鸡公鸡进行杂交改良。该研究以来源于鹿苑鸡的C5品系为父本,与C3品系母鸡杂交,测定后代的体重体尺、产蛋性能和蛋品质。结果发现,与C3相比,C5(父)×C3(母)生长发育速度快,产蛋性能低,蛋品质高。可见,C5(父)×C3(母)基本达到杂交改良的目的,后期选育中需要重点提高C5品系产蛋性能。
The C3 line of local chicken breed Rugao yellow chickens has good laying performance,but the egg and eliminated hens of it are light in weight,so it is necessary to use big cocks from local chicken breed for cross improvement.In the current study,the cocks of C5 line derived from Luyuan chickens was used as sire and crossed with hens of C3 line.Then the body weight,body measurement,laying performance and egg quality of offspring were detected.The results showed that compared with C3,the growing and developing rate of C5(sire)×C3(hens)was faster,the laying performance was lower,and the egg quality was high er.In conclusion,C5(sire)×C3(hens)can achieve the purpose of cross improvement basically.The laying performance of C5 line should be improved in the late breeding.
