摘要
45日龄的商品代渝西乌鸡750只(雌雄各半),按性别随机分成3组,测定立体式笼养、垫料式地面平养及放牧散养3种饲养方式下的增重性能。结果表明:75、90日龄笼养公鸡平均体重显著大于垫料式地面平养和放牧散养(P<0.05);而120日龄放牧组公鸡均重明显高于其他2种饲养方式(P<0.05)。母鸡90、120日龄3种饲养方式没有显著差异(P>0.05)
750 Yuxi Dark-skin Chickens （375 males and 375 females）of commercial generation of 45d-old age were selected respectively and randomly divided into three groups to measure their body weight under the different raising ways of the three-dimensional cages （1）,padding straw on the ground （2）,putting out to pasture （3）, The chickens were weighted every 15days.The results showed that the weight of 90d-old age in group 1 was higher than that of the others （p〈0.05）,the body weight at 120d-old age in group 3was higher than that of the others.
