| Summary: | © 2020 Elsevier Ltd The effect of diet enriched with dried lemon (Citrus limon) peel was fed to Labeo rohita at three different levels (0, 1, 2.5, and 5 g kg−1) for a period of 60 days; the impact of the diet on the hematology, antioxidant activity and immunological reaction and gene expression against Aeromonas sorbia is reported. In both un-challenged and challenged groups treated with 2.5 g and 5 g kg−1 dried lemon peel diets, the enhanced significant changes are: the weight gain and specific growth rate, white blood cell and total protein content, the antioxidants: superoxide dismutase, catalase, glutathione peroxidase, and glutathione activities, the respiratory burst, alternative complement pathway, complement C3, and total immunoglobulin M levels. Similarly, the heat shock protein-70 and -90, superoxide dismutase, glutathione peroxidase, glutathione, interleukin-1β and −8, tumor necrosis factor alpha, inducible nitric oxide synthase, transforming growth factor beta, and immunoglobulin M were up-regulated significantly. Any dried lemon peel enriched diet increased the phagocytic and lysozyme activities significantly in both groups. In the un-challenged group treated with 0 g kg−1 diet or in both groups treated with 2.5 g kg−1 diet the SR was 100%. These results indicate that in both un-challenged and challenged-treated groups the 2.5 and 5 g kg−1 dried lemon peel enriched diets positively modulate growth rate, physiology, and antioxidant status, innate-adaptive immune response as well as antioxidant and immune related gene expression in L. rohita against A. sorbia. |
