摘要 试验选用324只1日龄AA肉鸡(公鸡),采用3×2因子设计,研究在不同能量水平的饲粮中添加植酸酶对肉鸡生长性能和养分利用率的影响。试验设3个能量水平(12.33、12.13、12.03MJ/kg)和2个酶水平(0、500FTU/kg),共计6个处理组,每个处理组6个重复,每个重复9只鸡,试验期42d。结果表明:饲粮添加植酸酶显著(P<0.05)或极显著(P<0.01)提高了肉鸡日增重、采食量,改善了饲料利用率,提高了干物质、粗蛋白、钙、磷的利用率,但对能量利用率没有明显影响(P>0.05);降低饲粮能量水平极显著降低了肉鸡对干物质、能量、钙的利用率(P<0.01),显著降低了其对磷的利用率(P<0.05),但对生产性能和粗蛋白利用率没有显著影响(P>0.05);植酸酶和能量对肉鸡饲料利用率、干物质和钙的利用率存在显著的交互作用(P<0.05),表现为处理2组能量水平条件下添加植酸酶在生长性能和养分利用率上改善幅度最大,表明植酸酶在适宜降低能量水平的饲粮中的作用效果更好。试验中,以能量水平为12.13MJ/kg的肉公鸡饲粮中添加500FTU/kg植酸酶(处理5组)为最佳组合。
