Probiotic feed additives can support the gut health of shrimp and thereby improve performance, production efficiency and disease resistance. Two experiments in white leg shrimp aimed to investigate the effects of a multi-species probiotic feed supplement (AquaStar, 3 g/kg feed, Biomin GmbH, Getzersdorf, Austria) in feed formulations with different marine meal levels (32% and 15%) on growth performance and resistance against . Juvenile shrimp were stocked in a recirculating aquaculture tank system at a density of 20 shrimp/46.8 L and were fed diets with and without the probiotic supplementation for 8 weeks. Afterwards, a bath immersion with was performed and mortality was observed over a period of 14 days. Independent of the diet formulation, probiotic supplementation significantly improved the survival rate of the shrimp and the specific growth rate while decreasing feed consumption and feed conversion ratio when compared to the control ( ≤ 0.042). After the immersion challenge, mortality was significantly decreased by 13.33% with probiotic supplementation in the high marine meal diet experiment ( = 0.042) and numerically decreased by 11.67% in the low marine meal diet experiment ( = 0.133). Overall, the results suggest that the beneficial effects of the probiotic can occur independently of the diet formulation.
益生菌饲料添加剂可以维持虾类的肠道健康，从而提高其生长性能、生产效率和抗病能力。针对凡纳滨对虾进行了两项实验，旨在研究在不同海鱼粉水平（32%和15%）的饲料配方中添加多物种益生菌饲料添加剂（AquaStar，3克/千克饲料，百奥明股份公司，奥地利格茨多夫）对生长性能和抗……能力的影响。将幼虾以20尾/46.8升的密度放养在循环水养殖池塘系统中，投喂添加和未添加益生菌的饲料，持续8周。之后，用……进行浸浴处理，并在14天内观察死亡率。与对照组相比，无论饲料配方如何，添加益生菌均显著提高了虾的存活率和特定生长率，同时降低了饲料消耗和饲料转化率（P≤0.042）。在浸浴攻毒后，在高海鱼粉饲料实验中，添加益生菌使死亡率显著降低了13.33%（P = 0.042），在低海鱼粉饲料实验中，死亡率在数值上降低了11.67%（P = 0.133）。总体而言，结果表明益生菌的有益效果不受饲料配方的影响。
