Abstract为研究饲料中添加壳寡糖对刺参Apostichopus japonicus肠壁菌群的影响,在刺参基础饲料中分别添加0.25%(G1)、0.50%(G2)、0.75%(G3)和1.00%(G4)的壳寡糖,另设对照组(G0),养殖50 d后采集各组刺参幼参(5.03 g±0.03 g)肠壁样品,并采用高通量测序技术分析刺参肠壁菌群结构特征。结果表明:壳寡糖添加组刺参肠壁的细菌多样性和丰度均高于对照组;各组样品肠壁优势菌门均为变形菌门和厚壁菌门;壳寡糖对刺参肠壁菌群组成产生了明显影响,对照组优势菌属为希瓦氏菌属Shewanella,而壳寡糖添加组希瓦氏菌属的相对比例均下降,对照组芽孢杆菌属Bacillus的相对比例较低,而壳寡糖添加组芽孢杆菌属的相对比例均较高或成为优势菌属;1.00%壳寡糖组各类菌属相对比例均较低,高浓度壳寡糖出现抑制现象。研究表明,饲料中添加壳寡糖可提高刺参肠壁细菌多样性和丰度,明显改善刺参肠壁菌群结构。
