摘要
Different levels of dietary soybean meal (SBM) as a fish meal (FM) replacer, with and without amino acid supplementation, for whiteleg shrimp, Litopenaeus vannamei reared in the biofloc system was examined in eight weeks of feeding trial. Eight experimental diets consisted of a basal diet with 0% FM replacement by SBM provided in clear sea water without biofloc system (S0SW), four diets replacing FM at 0% (S0), 33% (S33), 67% (S67) and 100% (S100) by SBM, and three diets replacing FM at 33% (S33A), 67% (S67A) and 100% (S100A) by SBM supplemented with amino acids (methionine and lysine) in the seawater biofloc system. Results of water quality analyses showed significantly lower total suspended solids and nitrate for S0SW group than all other treatments. Diets S0 and S33A resulted in higher weight gain and specific growth rate among all groups, with no significant differences with S33 group. In addition, whole-body protein and amino acid compositions of shrimp fed S0SW were lower than most biofloc groups. Haemolymph parameters showed significant differences in total protein, cholesterol and triglyceride between groups S0 and S0SW. Also, superoxide dismutase activity showed a decreasing trend with increasing replacement level. In conclusion, based on these results, SBM could replace up to 33% of FM with or without amino acid supplementation in juvenile whiteleg shrimp diets reared in the biofloc system.

不同水平的膳食大豆粉（SBM）作为鱼粉（FM）替代品，补充和不添加氨基酸，用于白虾，在8周的饲养试验中检查了在生物絮凝体系中饲养的百日香 8种实验饮食包括在没有生物絮凝系统（S 0 SW）的清澈海水中提供0％25 FM替代的基础饮食，4种饮食替代0％25（S 0），33％25（S 33） ，67％25（S 67）和100％25（S100），三种饮食替代33％25（33A）的FM，在海水生物絮凝体系中补充有氨基酸（甲硫氨酸和赖氨酸）的SBM的67％25（S 67A）和100％25（S100A）水质分析结果显示，S 0 SW组的总悬浮固体和硝酸盐比所有其他处理显着降低饮食S 0和S 33 A各组之间的体重增加和比生长率均较高，与S 33组无显着性差异。另外，虾饲料S 0 SW的全身蛋白质和氨基酸组成均低于大多数生物絮凝组。血淋巴参数显示总蛋白含量有显着差异，胆固醇和三酸甘油酯组S 0和S 0之间SW 另外，超氧化物歧化酶活性随着替代水平的增加呈现下降趋势。总之，基于这些结果，SBM可以在生物絮凝系统中饲养的青少年白虾虾饮食中替代高达33％的25％的FM或氨基酸补充。关键词：絮凝技术鱼粉豆粕氨基酸
