The aim of the present study was to determine whether açai oil (Euterpe oleraceae) addition in the diets of juvenile Nile tilapia (Oreochromis niloticus) in biofloc system would stimulate hepatic energy metabolism and antioxidant responses. Treatments are as follows: T0 (6%‐soybean oil), T1 (1%‐AÇAI; 5%‐SOY), T3 (3% AÇAI; 3%‐SOY) and T6 (6%‐AÇAI). In the liver, reactive oxygen species levels were significantly lower in T1, T3 and T6 than in T0, lipid peroxidation levels were significantly lower in T3 and T6, and nitric oxide levels were significantly lower in the T6 than in T0. Glutathione peroxidase activity was significantly higher in the T3 and T6 than in T0, while superoxide dismutase activity and total antioxidant capacity levels were significantly higher in the T6 than in T0. Adenylate kinase activity was significantly lower in the T6 than in T0. These results suggest that the açai oil addition in Nile tilapia diets stimulated antioxidant responses.

罗非鱼日粮中添加阿萨伊油对性能，肝能量代谢酶和抗氧化反应的影响

本研究的目的是确定少年尼罗罗非鱼（Oreochromis niloticus）的饮食中是否添加了巴西油（Euterpe oleraceae）。生物絮凝系统中的）会刺激肝能量代谢和抗氧化反应。处理方法如下：T0（6％豆油），T1（1％-AÇAI； 5％-SOY），T3（3％AÇAI； 3％-SOY）和T6（6％-AÇAI）。在肝脏中，T1，T3和T6中的活性氧水平显着低于T0，T3和T6中的脂质过氧化水平显着降低，T6中的一氧化氮水平显着低于T0。T3和T6中的谷胱甘肽过氧化物酶活性显着高于T0，而T6中的超氧化物歧化酶活性和总抗氧化能力水平显着高于T0。T6中的腺苷酸激酶活性明显低于T0。这些结果表明，在尼罗罗非鱼饮食中添加阿萨伊油可刺激抗氧化反应。
