| 摘 要： | 对来源于遗传基础相同且含地方鸡种血缘的矮小型（ｄｗ）叫和正常型（ＤＷ）后代的早期生长、饲料报酬、体尺和屠宰性状进行比较。结果显示：１４周龄时ｄｗ后代母鸡的体重为ＤＷ后代鸡的９６％～１００％，公鸡为９５％～９６％；ｄｗ后代鸡的存活率高２％～３％；ｄｗ基因对后代肉鸡的饲料报酬、主要体尺和屠宰性状无显著影响。

| Abstract: | Quality broilers of same genetic base from the progeny Of dwarf and normal females were compared for early growth,feed efficiency, boby size and slaughter Performance. The results aPPearred that bodyweight at 14wbs in female broilers from heprogeny of dwarf was 96 ~ 100 percent Of that from the normal. In male broilers, it was 95 ~ 96 percent from the dwarf compared tothe normal, and the livability was 2 ~ 3 percent higher from the progeny of dwarf. There were no significant effects on feed efficiency, body size and slaugher performance. |
