Comparative analysis between synthetic vitamin E and natural antioxidant source...
Pereira, Ricardo; Costa, Mónica; Velasco, Cristina; Cunha, Luís M.; Lima, Rui C.; Baião, Luís F.; Batista, Sónia; Marques, Alexandra; Sá, TiagoSynthetic vitamin E is commonly used in aquafeeds to prevent oxidative stress in fish and delay feed and flesh oxidation during storage, but consumers’ preferences tend towards natural antioxidant sources. The potential of vegetable antioxidants-rich coproducts, dried tomato (TO), carrot (CA) and coriander (CO) was compared to that of synthetic vitamin E included in diets at either a regular (CTRL; 100 mg kg−1)...
Effects of dietary curcumin in growth performance, oxidative status and gut mor...
Xavier, Maria João; Navarro-Guillén, Carmen; Lopes, André; Colen, R.; Teodósio, Rita; Mendes, Rodrigo; Oliveira, Beatriz; Valente, Luisa M.P.An imbalance in the production and detoxification of reactive oxygen species and other oxidants can disrupt a l l types of cellular compounds, and lead to a state of oxidative stress. Preventing this state is essential to improve growth and health in animal production. Therefore, the aim of this work was to assess i f the dieta r y supple-mentation of curcumin cou l d improve the antioxidant status and intestin...
Physical processing or supplementation of feeds with phytogenic compounds, algi...
Valente, Luisa M.P.; Batista, Sónia; Ribeiro, Catarina; Pereira, Ricardo; Oliveira, Beatriz; Garrido, Inês; Baião, Luís F.; Tulli, FrancesaThis study assessed both the effectiveness of a physical-mechanical rupture method and the ability of feed additives (phytogenic compounds, alginate oligosaccharide and nucleotides) to enhance the utilization of G. gracilis by European seabass. A commercial-based diet was used as control diet (CTRL) and compared with five isoproteic (53.5% Dry matter, DM) and isolipidic (14.9% DM) diets containing 8% of G. grac...
Olfactory Sensitivity to Amino Acids in the Blackspot Seabream (Pagellus Bogara...
Barata, Eduardo N.; Ozorio, Rodrigo O.A.; Hubbard, Peter C.; Valente, Luisa M.P.; Canário, Adelino V.M.Intensive aquaculture is heavily dependent on high-quality fishmeal to meet their protein requirements. However, due to the increased demand, decreased availability, raising costs and the potential presence of organic and inorganic contaminants, it is of economical and environmental interest to replace fishmeal by a renewable protein sources. This is particularly challenging since replacing fishmeal may lack ap...
