Issue Date: | 2022 | Project: | Dieta Funcional Para Sustitución de Ingredientes Marinos en Peces: Maximización de Resistencia A Patogenos Via Refuerzo de Barreras Epitelialesy Herramientas de Inmunización | Journal: | Animals | Abstract: | The aim of the present study is to evaluate the potential of two functional additives as gill endogenous antioxidant capacity boosters in European sea-bass juveniles fed low-FM/FO diets when challenged against physical and biological stressors. For that purpose, two isoenergetic and isonitrogenous diets with low FM (10%) and FO (6%) contents were supplemented with 5000 ppm plant-derived galactomannan–oligosaccharides (GMOS) or 200 ppm of a mixture of garlic and labiate plant essential oils (PHYTO). A control diet was void from supplementation. Fish were fed the experimental diet for nine weeks and subjected to a confinement stress challenge (C challenge) or a confinement stress challenge combined with an exposure to the pathogen Vibrio anguillarum (CI challenge). Both GMOS and PHYTO diets attenuated fish stress response, inducing lower circulating plasma cortisol and down-regulating nfκβ2 and gr relative gene-expression levels in the gill. This attenuated stress response was associated with a minor energetic metabolism response in relation to the down-regulation of nd5 and coxi gene expression. | URI: | http://hdl.handle.net/10553/119909 | ISSN: | 2076-2615 | DOI: | 10.3390/ani12233332 | Source: | Animals [EISSN 2076-2615], v. 12 (23), (Diciembre 2022) |
