【摘要】 选取初生AA幼雏 360羽 ,随机分为 4组 ,每组 3个重复 ,每组随机接受一种试验日粮 ,采用单因子试验设计 ,甲壳素水解蛋白的添加水平分别为 0 % ,1 % ,2 % ,3 % ,经过 4周的试验 ,测定日粮中添加不同甲壳素水解蛋白对肉仔鸡生长发育和ARN %的影响。研究结果表明添加2 %～ 3 %的甲壳素水解蛋白 ,可显著提高肉仔鸡的ADG (P <0 0 5) ,添加 1 %～ 2 %的甲壳素水解蛋白 ,可显著改善肉仔鸡的F/G (P <0 0 5)及显著提高肉仔鸡的ARN % (P <0 0 5)。综合考虑各种因素 ,在肉仔鸡基础日粮中CP水平为 2 0 %时 ,甲壳素水解蛋白的适宜添加水平为 2 %。更多还原

【Abstract】 To study the influence of protein hydrolysat of shrimp crust on broiler growth and ARN%, 360 chicken AA were divided into 4 groups, 3 repetition of every group, at random. Every group received a kind of test ration. The treating level of protein hydrolysat of shrimps crust was 0%, 1%, 2%, 3%, respectively. The tests lasted 4 weeks. The results indicated that 2%～3% of the protein hydrolysat of shrimp crust improved ADG (P <0.05), 1%～2% of the protein hydrolysat of shrimp crust improved F/G and ARN% (P <0.05). It is suggested that CP level be 20% in basal ration, shrimp crust protein hydrolysat be 2%.更多还原
