| 摘 要： | 为了研究日粮蛋白质水平对肉用乌骨鸡生产性能的影响,试验选用15周龄、体重接近的健康乌骨鸡288只,随机分成3个试验组,每个组设3个重复。3组饲喂粗蛋白质含量分别为17.85%、20.46%、22.45%的3种日粮。试验期为4周。试验结果显示:在16~20周龄,试验Ⅱ组的鸡日增重最高,为18.87 g/d。其日增重与试验Ⅰ、Ⅲ相比较,分别提高了13.89%、8.35%,差异显著(P0.05)。

| Abstract: | 288 15-week old healthy black-bone chicken were selected and randomly assigned into 3 trial groups,3 replicates in each group to investigate the effects of dietary crude protein levels on growth performance of black-bone chicken.Crude protein levels were 17.85 %,20.46 % and 22.45 %,respectively.The trial phase was 4 weeks.The results indicated that from 16 to 20 week age,group II showed the highest daily weight gain 18.87 g/d,compared to group I and group III,daily weight gain increased by 13.89 % and 8.35 ... |
