| 摘 要： | 以艾维因肉仔鸡为研究材料 ,通过饲养、代谢试验 ,研究低有效磷饲粮中添加植酸酶对肉仔鸡胫骨质量及矿物代谢的影响。 10 0只艾维因肉仔鸡随机分为 5组 ,每个组设 4个重复。第 1组喂标准饲粮 ;第 2 ,3,4,5组为低有效磷 (质量分数为 0 .0 0 2 )饲粮 ,分别加植酸酶 0 ,35 0 ,5 0 0 ,65 0FTU kg。饲养试验分两个阶段 :0～ 3周、4～ 6周。试验期为 5周 ,观察各组肉仔鸡的胫骨质量、矿物质代谢的变化。结果表明 :在低有效磷饲粮中添加植酸酶对矿物代谢有一定积极影响 ,以植酸酶最大添加量 65 0FTU kg组的效果为最佳

| Abstract: | We conducted an experiment to analyze the effects of microbial phytase in low inorganic phosphorus diets on broilers. 100 4 day birds were randomly divided into 5 groups, each having four replications. Broilers in group 1 were fed on basal diets of inorganic phosphorus as controlled. Broilers in group 2,3,4,5 were fed on low P basal diets. Microbial phytase was added of 0, 350, 500, 650 FTU/kg per kilogram to the diets of group 2,3,4,5. The experiment lasted 5 weeks. It indicated that adding phytase to low P diets for broilers could, to some degree, improve mineral metabolism. The 650 FTU/kg group was the best in all low P groups. |
