摘要
在对虾配合饲料中添加不同剂量（0．0．5、1．0、1．5、2r．g／g）的β-葡聚糖投喂凡纳滨对虾60d，分析β-葡聚糖对凡纳滨对虾免疫相关酶活性的影响。结果表明：1．5mg／g处理组肌肉溶菌酶活力显著高于对照组（P〈0．05）；0．5、1．0、1．5mg／g处理组的POD活力均显著高于对照组（P〈0．05）；0．5、1．0、1．5、2．0mg／g各处理组血清碱性磷酸酶（AKP）和酸性磷酸酶（ACP）均极显著高于对照组（P〈0．01），其中1．5mg／g组的ALP和ACP活力最高。表明饲料中添加葡聚糖能有效提高虾体免疫力，活官添加剂量为1．0-1.5mg／g．
The effect of β-- glucan on enzyme activity of immunity in Pacific white leg shrimp Litopenaeus vannmei were investigated. Five diets of various concentrations （mg/g） （0,0.5,1.0,1.5 and 2.0） of β- glucan were fed for 60 d. The results showed that four immunological factors including bacteriolysin（LSZ） in muscle tissue, perox- idase（POD）, acid phosphatase（ACP） and alkaline phosphatase（AKP） activities in blood serum of the shrimp were increased after fed β- glucan. The activity of LSZ was significantly higher in the groups treated with 1.5 mg/g β- glucan （ P 〈 0.05 ）, and the activity of POD was significantly higher in the groups treated with 0.5, 1.0 and 1.5 mg/g β- glucan （ P 〈 0.05）, and the activities of ACP and ALP was very significantly higher in the groups treated with 0.5,1.0,1.5 and 2.0 mg/g β- glucan （P 〈0. 01） than the control group. It indicated that β- glucan could increase the immunological activity of the shrimp and the optimum concentration was 1.0 - 1.5 mg/g.
