摘要
To accomplish the goal of sustainable aquaculture, substitution of fish meal (FM) with available and effective alternative ingredients is necessary. The present study evaluated the effects of fermented soybean meal (FSBM) substituted to FM on growth, innate immune responses, nutrient digestibility, and morphological changes in hepatopancreas of white shrimp Litopenaeus vannamei, fed a low FM diet. The FM protein was replaced by FSBM at 0%, 25% (25% FSBM), 50% (50% FSBM), 75% (75% FSBM), and 100% (100% FSBM) in the control diet (including 15% FM). Experimental diets were each fed in triplicates to juvenile shrimp with initial weight of 5.53 g in a closed recirculation system for eight weeks. Shrimp fed different diets exhibited similar (p > 0.05) growth performance and morphology in hepatopancreas. Shrimp fed the 75% FSBM diet had higher total hemocyte count than other dietary groups. Shrimp fed the 75% FSBM diet exhibited the highest phenoloxidase (PO) activity, followed by shrimp fed 50% FSBM and 100% FSBM diets, and lowest in shrimp fed the control and 25% FSBM diets. Apparent digestibility of dry matter, protein and lipid showed the highest performance in shrimp fed the 75% FSBM diet compared with other dietary treatments. Results indicate that FSBM can completely replace fish meal protein without any negative effects on growth and morphology in hepatopancreas. The adequate replacement levels is suggested at 75% to improve innate immune responses and nutrient digestibility for white shrimp.

为了实现可持续水产养殖的目标，需要具有可用和有效的替代成分的鱼粉（FM）替代。本研究评估了在白虾Litopenaeus vannamei的肝脏肝癌的生长，先天免疫应答，营养消化，营养消化率和形态学变化的发酵大豆膳食（FSBM）的影响，喂养低FM饮食。 FM蛋白由0％，25％（25％FSBM），50％（50％FSBM），75％（75％FSBM）和100％（100％FSBM）的FSBM取代（包括15个％fm）。实验饮食各自以三份素喂食到少年虾，初始重量为5.53克，在闭合的再循环系统中持续八周。虾喂养不同的饮食在肝癌中表现出类似的（p> 0.05）生长性能和形态。虾喂养75％FSBM饮食的总血液细胞数量比其他膳食群更高。虾喂养75％的FSBM饮食表现出最高的酚氧基酶（PO）活性，其次是饲喂50％FSBM和100％FSBM饮食的虾，虾中最低喂养对照和25％FSBM饮食。与其他膳食处理相比，干物质，蛋白质和脂质的表观消化率显示出虾饲喂75％FSBM饮食的最高性能。结果表明，FSBM可以完全取代鱼粉蛋白，而不会对肝病中的生长和形态产生任何负面影响。适当的替代水平以75％提高，以改善白虾的先天免疫应答和营养消化率。
