ABSTRACT This study investigates the effects of microencapsulated garlic (Allium sativum) extract (G) on growth, immune response, and antioxidant status of rainbow trout juveniles. A total of 300 fish (13.05 ± 0.36 g) were divided into five groups (three replicates per group) and fed with the experimental diets containing G (0, 0.25, 0.5, 1, and 2%) for 40 days. The results indicated that dietary supplementation with garlic could significantly improve growth performance, Feed conversion ratio (FCR) fish fed with G3 diet compared to control. Proximate composition of fish showed significantly higher protein content and lower lipid content in the fish fed G3 diet compared to control. Significantly higher total serum protein and lysozyme activity were found in the fish fed diet supplemented with 0.5% garlic extract, whereas the activities of liver enzymes (ALP, AST, ALT) were significantly lower in the fish fed diet containing garlic extract than in fish fed the control diet. The highest superoxide dismutase (SOD) and catalase (CAT) activities were in fish fed diet supplemented with garlic extract. Therefore, the current research suggests that microencapsulated garlic extract could be considered as a good food additive to improve growth, non-specific immune response, and antioxidant capacity of rainbow trout.

微胶囊大蒜(Allium sativum)提取物对虹鳟鱼(Oncorhynchus mykiss)幼鱼生长性能、身体成分、免疫反应和抗氧化状态的影响

摘要 本研究调查了微胶囊化大蒜 (Allium sativum) 提取物 (G) 对虹鳟鱼幼鱼生长、免疫反应和抗氧化状态的影响。总共 300 条鱼 (13.05 ± 0.36 g) 分为五组(每组三个重复),并用含有 G(0、0.25、0.5、1 和 2%)的实验饮食喂养 40 天。结果表明,与对照相比,饲喂大蒜的日粮可以显着提高生长性能、饲喂 G3 日粮的鱼饲料转化率 (FCR)。与对照组相比,喂食 G3 饮食的鱼的近似组成显示出显着更高的蛋白质含量和更低的脂质含量。在添加 0.5% 大蒜提取物的鱼饲料中发现显着更高的总血清蛋白和溶菌酶活性,而饲喂含有大蒜提取物的鱼的肝脏酶(ALP、AST、ALT)的活性显着低于饲喂对照饲料的鱼。最高的超氧化物歧化酶 (SOD) 和过氧化氢酶 (CAT) 活性在鱼饲料中添加大蒜提取物。因此,目前的研究表明,微胶囊大蒜提取物可作为一种良好的食品添加剂,以改善虹鳟鱼的生长、非特异性免疫反应和抗氧化能力。
