| Résumé: | The aquaculture industry has currently experienced a growing interest in implementing antioxidants from natural origin in diets because the synthetic ones that have been used are associated to carcinogenic and teratogenic effects. Additionally, synthetic antioxidants have been included in such diets to prevent lipid oxidation during storage and distribution of the organisms without an approach from their health status point of view since they require micronutrients, such as bioactive compounds, mainly antioxidants. Thus, mango and roselle by-products rich in bioactive compounds were included in the aquaculture diet, assessed on their antioxidant properties and performance on tilapia Oreochromis niloticus, and compared with reference and commercial diets. The results of the different experimental diets indicated that their properties increased -according to the analyses of anti-radical antioxidant activity 1,1-diphenyl-2-pricrylhydrazyl (DPPH●) ferric reducing antioxidant power (FRAP) of ferric ion (Fe III) and phenolic compound concentration- with the inclusion of the by-products included as novel inputs. With respect to the zootechnical parameters assessed, no differences were found, so no negative effect was considered during feeding with the novel functional diet. Therefore, the potential use of the assessed by-products in commercial diets is inferred, suggesting assessment during the fattening stages of the species under commercial rearing conditions. |
