摘    要:在基础饲料中添加不同水平蛋氨酸锌(添加水平分别为0、50、150 mg Zn/kg)并饲喂凡纳滨对虾,养殖14 d后,取样测定对虾鳃组织中Toll受体mRNA和溶菌酶mRNA的表达水平以及肝胰腺、肌肉和血淋巴中超氧化物歧化酶(SOD)和溶菌酶(LSZ)活性,并进行溶藻弧菌人工急性感染试验。结果表明,凡纳滨对虾肝胰腺及肌肉中锌蓄积水平随饲料锌添加量的增加而显著增加(P<0.05),肝胰腺中锌蓄积更明显。添加50 mg Zn/kg组(锌含量为73.25 mg Zn/kg饲料)对虾鳃组织中的Toll受体mRNA和溶菌酶mRNA表达量均显著高于未添加锌组和添加150 mg Zn/kg组(P<0.05)。添加50 mg Zn/kg组对虾肌肉、肝胰腺和血淋巴中溶菌酶活性显著高于未添加锌组(P<0.05)。添加50 mg Zn/kg组对虾肝胰腺和血淋巴中的SOD活性也显著高于未添加锌组,但与添加150 mg Zn/kg组无显著差异。而肌肉中SOD活性在添加150 mg Zn/kg组中最高。经溶藻弧菌人工急性感染后,添加50 mg Zn/kg组对虾半致死时间和全致死时间大于未添加锌组和添加150 mg Zn/kg组。本研究表明,相比摄食未添加锌组饲料和添加150 mg Zn/kg组饲料,凡纳滨对虾的免疫抗菌机能在摄取添加50 mg Zn/kg(锌含量为73.25 mg Zn/kg饲料)饲料时得到改善。

关 键 词:凡纳滨对虾   蛋氨酸锌   Toll受体mRNA   溶菌酶mRNA   超氧化物歧化酶   溶菌酶
