研究了芽孢杆菌益生素对斑节对虾生长性能和微生物区系的影响。用三种饮食中的一种喂养虾120天;单独的对照饮食或补充有由活喷雾芽孢杆菌（LS）或冻干芽孢杆菌（FD）组成的益生菌。试验期间，三个处理组的肝胰脏、肠道和养殖水体中的可培养细菌数量相对稳定。试验30 d后，各益生菌组肝胰腺和肠道中的芽孢杆菌数量显著增加（P < 0.05），此后保持相对稳定，而对照组无明显变化。添加LS和FD的对虾肝胰腺、肠道和养殖水体中弧菌含量显著低于对照组（P < 0.05）。结果表明，与对照组相比，LS和FD益生菌组对虾的特定生长率（SGR）和饲料转化率（FE）显著提高（P < 0.05）。益生菌具有通过减少弧菌和改善生长性能来增强对虾养殖的潜力。
The effects of Bacillus probiotic forms on growth performance and microbiota were examined in black tiger shrimp (Penaeus monodon). Shrimp were fed for 120 days with one of three diets; a control diet alone or supplemented with either probiotics consisting of live-sprayed Bacillus (LS) or freeze-dried Bacillus (FD). Culturable bacteria counts in the hepatopancreas, intestine and culture water of the three treatments were relatively constant during the experiment. Bacillus numbers in the hepatopancreas and intestines of probiotic-treated groups increased significantly (P < 0.05) after 30 treatment days and remained relatively constant afterwards while no appreciable changes occurred in the control. Shrimp supplemented with LS and FD contained significantly lower concentrations of Vibrio (P < 0.05) in the hepatopancreas, intestine and culture water, compared to those in the control group. Shrimp treated with LS and FD probiotic bacteria showed a significant improvement (P < 0.05) in specific growth rate (SGR) and feed efficiency (FE), compared to those of control group. Probiotic bacteria have the potential to enhance shrimp culture by reducing Vibrio and improving growth performance.
