中文摘要：为了评价纳豆菌抗菌脂肽对凡纳滨对虾(Litopenaeus vannamei)生长的影响和抑制对虾养殖源头弧菌数的作用效果,在基础饲料中添加0(A0对照组)、50(A1组)、100(A2组)、200 mg/kg(A3组)NT-6抗菌脂肽,投喂平均体重为4.10(±0.10)g的凡纳滨对虾3周,测量和计算对虾的生长和形态指标以及染弧菌试验前后各试验组和对照组水体和虾体中副溶血弧菌、溶藻弧菌数,染菌后观察试验组和对照组对虾的死亡情况并计算对虾的存活率。结果表明,在饲料中添加一定量的NT-6抗菌脂肽可显著促进凡纳滨对虾的生长和抑制水体和虾体中弧菌的生长,其中A2组(100 mg/kg)的促生长和抑菌效果最好。

外文摘要：To evaluate the effects of natto antimicrobial lipopeptide on growth promoting of Litopenaeus vannamei and inhibition of Vibrio during breeding process of shrimps, authors added 0 mg/kg （group A0）, 50 mg/kg （group A1）, 100 mg/kg （group A2） and 200 mg/kg （group A3） NT-6 antibacterial lipopeptide into the basic diet, fed the L. vannamei with average weight 4.10（±0.10） g for 3 weeks, measured and calculated the index of growth and morphology of shrimp, the number of V. parahaemolyticus and V. alginolyticus of experimental groups and control group in water and shrimp body before and after the contaimination, and observed the death rate of shrimp in all experimental groups and control group after they were infected, and calculated the survival rate of shrimp. The results showed that adding a certain amount of NT-6 antimicrobial peptide in the feed could significantly promote the growth of L. vannamei and inhibit the growth of Vibrio in water and shrimp, and growth promoting and antimicrobial effects of A2 group （100 mg/kg） was the best.
