摘要
用寿光鸡与黑乌骨鸡、斗鸡和AA鸡进行杂交试验,结果表明:①寿光鸡与黑乌骨鸡杂交,其F1代体增重介于两品种之间,跖长比寿光鸡降低17.2%;羽型多表现为扁羽,约15%为丝状羽;皮肤为白色;均为5趾。②鲁西斗鸡与寿光鸡杂交F3代与寿光鸡相比,体增重降低6.3%,料重比增加5.9%,胸宽增加5.3%。③寿光鸡与AA鸡杂交,F1代增重速度比寿光鸡本身提高85.2%,料重比降低14.3%。④白乌骨鸡比黑乌骨鸡增长快,F1代比黑乌骨鸡100日龄增重提高24%,比白乌骨鸡本身增重快9.1%。
The crossing combinations have been conducted by the ShouGuang chicken×Silkies,Fighting chicken×AA chicken.The results showes that①in ShouGuang chicken×black-Sikies,the average body gain of F1progenies was the middle between ShouGuang chicken and black silkies,and at42-days of age,the toe length decreased17.2%than ShouGuang,and the F1Progenies appeares more fang-shaped feather(about 15%silk-shaped feather),white skin and five toes;②Luxi Fighting chicken F3hybrid Progenies in comparison with ShouGuang chicken exhibited that the average body gain decreased6.3%,the ratio of feed/gain increased5.9%and the breast width enhanced5.3%;③The F1hybrid progenies of ShouGuang chicken×AA chicken showed the rate of feed/gain went up85.2%than ShouGuang chicken at13-weeks old,but the ratio of feed/gain decreased14.3%;④White silkies grew fast than black silkies.At 100-days of age,the body gain of F1increased24%and9.1%than black silkies and white silkies separately.
