Abstract
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.
