This study was performed to evaluate the supplementation of α‐lipoic acid in diets on the growth performance of giant gourami juvenile. This study used the completely randomized design experimental method containing four diets treatments and four replications. The experimental diets comprised L0 as control (0.0 g/kg), L03 (0.3 g/kg), L06 (0.6 g/kg) and L09 (0.9 g/kg), which made as isonitrogenous and isocaloric diet. The experimental diets were given on the giant gourami juvenile (7.05 ± 0.08 g initial weight) for 60 days. The supplementation of α‐lipoic acid on L06 treatment significantly improved the feed intake, specific growth rate, feed conversion ratio, protein retention, lipid retention, liver lipid, liver glycogen and superoxide dismutase enzyme. On the other hand, the highest malondialdehyde, blood triglycerides and hepatosomatic index were obtained from L0 treatment (Duncan: p < 0.05). The water quality parameters (temperature, pH, DO, nitrite, nitrate and TAN) had no significant difference among treatments. This study concludes that the supplementation of α‐lipoic acid in diet improves the growth performance of giant gourami juvenile.

日粮中添加α-硫辛酸对巨型古拉米（Osphronemus goramy）幼鱼生长性能的评估

这项研究旨在评估日粮中添加α-硫辛酸对巨型古拉米幼鱼生长性能的影响。这项研究使用了完全随机的设计实验方法，其中包含四种饮食疗法和四次重复。实验饮食包括作为对照的L0（0.0 g / kg），L03（0.3 g / kg），L06（0.6 g / kg）和L09（0.9 g / kg），这些饮食被制成等氮和等热量饮食。实验性饮食以巨型古拉米鱼（7.05±0.08 g初始体重）喂养60天。L06处理中补充α-硫辛酸可显着改善饲料摄入，比生长速率，饲料转化率，蛋白质保留，脂质保留，肝脂质，肝糖原和超氧化物歧化酶。另一方面，最高的丙二醛p  ＜0.05）。各处理之间的水质参数（温度，pH，DO，亚硝酸盐，硝酸盐和TAN）没有显着差异。这项研究的结论是，在饮食中补充α-硫辛酸可改善巨型古拉米幼鱼的生长性能。
