摘要(Abstract)：

在凡纳滨对虾饲料中添加不同量微生物植酸酶(0,500,1000,2000 U/kg),观察虾的存活率、增重率、饲料系数及虾体和虾壳成分,研究饲料中添加植酸酶对凡纳滨对虾生长性能的影响。结果表明:饲养8周后,饲料中添加500~2000 U/kg植酸酶对凡纳滨对虾增重率、存活率和饲料利用无显著影响(P>0.05);植酸酶添加各组与对照组虾体的水分、粗蛋白、脂肪、灰分、总钙和总磷含量差异不显著;虾壳中粗灰分和钙含量在500和1000 U/kg组显著高于对照组和2000 U/kg组(P<0.05),虾壳磷含量在各饲料组间差异不显著。血清磷浓度在对照组和2000 U/kg组显著高于500 U/kg组(P<0.05),血清钙浓度在组间差异不显著,血清碱性磷酸酶活性以对照组最高,显著高于500和1000 U/kg组。结果说明,在特定试验条件下,饲料中添加植酸酶对凡纳滨对虾幼虾的虾壳和血清成分有显著影响(P<0.05),对幼虾生长性能影响不显著(P>0.05)。
