Growth, biochemical and haematological parameters, and oxidative biomarkers were evaluated in juveniles of silver catfish (Rhamdia quelen). Fish were fed with tocopherol (0, 200, 300 and 400 mg kg−1) during an experimental period of 60 days. Growth parameters of the silver catfish showed no changes with the addition of tocopherol in diets. Tocopherol favoured the deposition of polyunsaturated fatty acids in muscle tissue, changed the erythrocyte count and increased resistance of the erythrocytes. The inclusion of tocopherol at 300 mg kg−1 in diets reduced oxidative stress in the brain, gills, liver and kidney. The addition of this compound improved the stability of biological membranes. The antioxidant protection exerted by tocopherol decreased ROS activity, and increased deposition of unsaturated fatty acids and oxidative stability, indicating favourable fish health. Silver catfish that ingested tocopherol in the diet obtained a higher body deposition of polyunsaturated fatty acids. Results of the present study recommend inclusion of tocopherol at 300 mg kg−1 and higher in silver catfish diets. [ABSTRACT FROM AUTHOR] |
