The present study was conducted to evaluate the supplemental effects of fermented noni juice on growth performance, immune response, antioxidant status, intestinal microflora and disease resistance of yellow catfish that fed with high-fat diet. Triplicate groups of yellow catfish (1.00 ± 0.05 g) were fed two levels of lipid (80.00 and 160.00 g/kg dry matter) and two levels of fermented noni juice (0.00 and 20.00 g/kg dry matter) for 56 days. The results showed that high-fat intake could affect growth (weight gain declined) and lead to oxidative stress (superoxide dismutase, catalase and glutathione peroxidase activities declined and malondialdehyde accumulation), immunosuppression (alkaline phosphatase, phagocytic index, respiratory burst, complement C3, C4 and immunoglobulin G declined) and intestinal microflora altered (Proteobacteria and Bacteroides decreased and Firmicutes increased). The dietary fermented noni juice supplementation could mitigate the adverse effect of high-fat intake on yellow catfish growth, oxidative stress, immunosuppression and intestinal microflora homeostasis. After challenge with Aeromonas hydrophila, the cumulative mortality of yellow catfish fed with high-fat diet was higher than that of fish fed high-fat diet supplemented with fermented noni juice.

发酵诺丽果汁对高脂饲料喂养的黄颡鱼幼鱼生长、抗氧化状态、免疫反应、肠道微生物群和对嗜水气单胞菌抗性的影响

本研究旨在评估诺丽发酵汁对高脂饮食黄鲶的生长性能、免疫反应、抗氧化状态、肠道微生物群和抗病能力的补充作用。三组黄鲶(1.00 ± 0.05 g)被喂食两种水平的脂质(80.00 和 160.00 g/kg 干物质)和两种水平的发酵诺丽汁(0.00 和 20.00 g/kg 干物质),持续 56 天。结果表明,高脂肪摄入会影响生长(体重增加下降)并导致氧化应激(超氧化物歧化酶、过氧化氢酶和谷胱甘肽过氧化物酶活性下降和丙二醛积累)、免疫抑制(碱性磷酸酶、吞噬指数、呼吸爆发、补体C3、C4 和免疫球蛋白 G 下降)和肠道菌群改变(变形杆菌和拟杆菌减少,厚壁菌增加)。膳食发酵诺丽果汁补充剂可以减轻高脂肪摄入对黄鲶生长、氧化应激、免疫抑制和肠道微生物群落稳态的不利影响。挑战后嗜水气单胞菌,高脂饲料喂养的黄鲇鱼的累积死亡率高于添加发酵诺丽果汁的高脂饲料喂养的鱼。
