This study was conducted to evaluate the effect of dietary administration of citric acid and lemon juice (Citrus limon) on growth performance, serum, and mucus immune responses, related-genes expression of growth (GH, IGF-I), and immune (Lyz, IL-1) in common carp (Cyprinus carpio). In this study, 300 common carp (mean weight 15 ± 0.4 g) were randomly distributed between fifteen, 300-l fiberglass holding tanks. The fish were fed in five groups (each with three replicates) containing 0.5 and 1% citric acid, 0.5 and 1% lemon juice (Citrus limon) per kg feed, and also control with a basal diet without additives for eight weeks. Obtain results showed that fish fed with the diet containing citric acid had significantly higher growth indices compared to the control group (P <0.05). Also, the results indicated a significant increase in the innate immune responses including serum and mucus immunoglobulin and lysozyme, when the diet was supplemented with 1% citric acid (P <0.05). The levels of alanine aminotransferase and Glutathione S-transferase enzymes showed a significant reduction in the fish fed with additives, while the activity of alkaline phosphatase and lactate dehydrogenase enzymes were significantly reduced in the fish fed with a diet containing 1% citric acid (P <0.05). Regarding the genes expression, results revealed that the growth (GH, IGF-I) and immune (Lyz, IL-1) genes were significantly influenced by dietary supplementation, indicating that the genes expression were increased in compared to the control group (P <0.05). In conclusion, the results of this study showed that dietary administration of citric acid and lemon juice (Citrus limon), especially 1% citric acid, have been improved the growth and some immune indices in common carp (Cyprinus carpio). |
