摘　　要：旨在探讨饲料中添加凝结芽孢杆菌对凡纳滨对虾幼虾生长性能和非特异性免疫力的影响。选用的凡纳滨对虾幼虾,平均分为4个组,在基础日粮中分别添加0.0%(Ⅰ组,对照组)、0.5%(Ⅱ组)、1.0%(Ⅲ组)、和1.5%(Ⅳ组)的凝结芽孢杆菌制剂,饲养20d。结果表明:随着凝结芽孢杆菌添加量的增加,试验组凡纳滨对虾的增质量率和特定生长率都显著高于对照组(P<0.05),同时显著降低饵料系数,提高养殖的存活率(P<0.05)。凡纳滨对虾的超氧化物歧化酶(SOD)和碱性磷酸酶(AKP)活性在添加1.5%的凝结芽孢杆菌组分别达到最大值,并显著高于对照组(P<0.05)。试验组的酸性磷酸酶(ACP)也显著高于对照组(P<0.05),但试验组间差异不显著(P>0.05),3个试验组的酚氧化酶(PO)活性、过氧化物酶(POD)活性均与对照组差异不显著(P>0.05)。说明,添加凝结芽孢杆菌可在一定程度上提高凡纳滨对虾幼虾的生长性能和改善其非特异性免疫力。An experiment was conducted to investigate the effects of adding Bacillus coagulas preparation on growth performance and non-specific immunity of Litopenaeus vannamei.Litopenaeus vannamei were randomly allotted to 4groups.Four diets were added 0.0%（groupⅠ,control group）,0.5%（group Ⅱ）,1.0%（groupⅢ）and 1.5%（groupⅣ）Bacillus coagulas preparation in basal diet,respectively.The experiment lasted for 20 days.The results showed that the mass gain ratio,the survival rate and specific growth ratio increased gradually as adding amount of Bacillus coagulas in the diet,while the feed conversion ratio decreased.The activity of superoxide dismutase（SOD）and alkaline phosphatase（AKP）got the maximum value respectively at 1.5% Bacillus coagulas,significantly higher than that of the control group（P〈0.05）.The activity of acid phosphatase（ACP）had the similar situation.The activity of phenoloxidase（PO）and peroxidase（POD）was not significant（P〉0.05）.In conclusion,adding Bacillus coagulas in basal diet could promote growth performance and enhance non-specific immunity in the shrimp.
