摘要
为研究饲用复合酶制剂在蛋鸡低蛋白饲粮中的应用效果，将２０６１羽２８周龄的蛋鸡随机分成两组，分别饲喂对照饲粮和添加饲用复合酶制剂的试验饲粮，基础饲粮为根据蛋鸡可利用氨基酸需要量和饲料原料氨基酸可利用率配制的低蛋白饲粮。试验结果表明：与对照组相比，试验组的产蛋率提高１０５％，料蛋比降低０８５％；特别是当外界气温变化较大时，试验组蛋鸡的抗应激能力显著增加，生产性能未受应激影响。
layers at the age of 28 weeks were divided at random into two groups to observe the
effect of enzyme product supplementation in the lowprotein diet.The results indicated that
supplementaion of enzyme product increased laying rate by 1.05% and feed efficiency by 0.43%
compared with the control group. The results also indicated that supplementaiton of enzyme
product improved the antistress ability of layers,and the performance were not affected when
environmental temperture varied.
