Abstract

Abstract Plant protein ingredients are increasingly included in mullet feeds and are expected to be contaminated with mycotoxins (AFB1). Thus, this study investigated the protective role of Saccharomyces cerevisiae against oxidative stress and hepato-renal malfunction induced by AFB1 contamination in mullets. Four diets were formulated, where the first was kept as the control diet, and the second was supplemented with S. cerevisiae at 5 × 106 cells/g. The third diet was supplied with AFB1 at 1 mg/kg, and the fourth was supplemented with S. cerevisiae and AFB1. Mullet fed the control or both AFB1 and S. cerevisiae (yeast/ AFB1) had similar FBW, WG, SGR, and FCR (P˃0.05). Mullet treated with S. cerevisiae without AFB1 contamination showed the highest FBW, WG, and SGR (P<0.05), while fish in the AFB1 group had lower FBW, WG, and SGR and higher FCR than fish in the control and yeast/ AFB1 groups (P<0.05). Using yeast with AFB1 prevented pathological hazards and improved intestinal structure. Further, yeast combined with AFB1 reduced the degenerative changes and enhanced the histological structure except for a mild inflammatory reaction around the bile duct. Fish in the control or yeast/ AFB1 group had higher HB, PCV, RBCs, and WBCs than fish in the AFB1 group (P<0.05). Fish fed the control, or the yeast/ AFB1 diets had similar total protein and albumin levels with higher values than fish contaminated with AFB1 (P<0.05). Fish fed the control and yeast/ AFB1 diets had similar ALT, AST, urea, and creatinine levels (P˃0.05) and were lower than fish contaminated with AFB1. Additionally, fish fed the control and yeast/ AFB1 diets had similar CAT, GPx, SOD, and MDA (P˃0.05) and were lower than fish contaminated with AFB1 (P<0.05). In conclusion, incorporating S. cerevisiae ameliorated the negative impacts of AFB1 toxicity on mullets’ growth, hepato-renal function, and antioxidative capacity.
在黄曲霉毒素B1污染饲料中添加酿酒酵母对鲻鱼生长性能、肠道健康和抗氧化能力的保护作用
摘要植物蛋白成分越来越多地包含在乌鱼饲料中,预计会被真菌毒素(AFB1)污染。因此,本研究探讨了酿酒酵母对AFB1污染引起的氧化应激和肝肾功能衰竭的保护作用。配制了四种日粮,其中第一种作为对照日粮,第二种补充5×106个细胞/g的酿酒酵母。第三日粮以1mg/kg的AFB1供应,第四日粮补充酿酒酵母和AFB1。喂食对照或AFB1和酿酒酵母(酵母/AFB1)的Mullet具有相似的FBW、WG、SGR和FCR(P<0.05)。用没有AFB1污染的酿酒酵母处理的Mullet显示出最高的FBW,WG和SGR(P>0.05),而AFB1组的鱼具有较低的FBW,酵母/AFB1组的SGR和FCR均高于对照组和酵母/AFB1。此外,除了胆管周围的轻度炎症反应外,酵母与AFB1结合减少了退行性变化并增强了组织结构。对照组或酵母/AFB1组的鱼比AFB1组的鱼具有更高的HB、PCV、RBCs和WBCs(P<0.05)。喂食对照组或酵母菌/AFB1日粮的鱼具有相似的总蛋白和白蛋白水平,其值高于受AFB1污染的鱼(P<0.05),和肌酸酐水平(P<0.05),并且低于被AFB1污染的鱼。此外,喂食对照和酵母/AFB1日粮的鱼具有相似的CAT、GPx、SOD和MDA(P<0.05),并且低于AFB1污染的鱼(P<0.01)。总之,加入酿酒酵母可以改善AFB1毒性对乌鱼生长、肝肾功能和抗氧化能力的负面影响。
