Enzyme-rich extract and use thereof in pre-treatment of plant feedstuff-based d...
Peres, Helena; Belo, Isabel; Salgado, José Manuel Seara; Castro, Carolina; Teles, Aires Oliva; Fernandes, Helena; Moyano, Francisco J.The present disclosure relates to an enzyme-rich extract obtained through solid-state fermentation (SSF) of Brewer's Spent Grain (BSG) to be used as a feed additive in animal diets, preferably fish diets. The present patent application also discloses a pre-treatment process of plant feedstuff-based (PF) diets in order to increase the nutrient bioavailability of said diets, thus increasing their nutritional value.
In vitro evaluation of the interaction between exogenous carbohydrases produced...
Fernandes, Helena; Moyano, Francisco J.; Fernandes, Nelson; Salgado, José Manuel Seara; Aires, Tiago; Belo, Isabel; Oliva-Teles, Aires; Peres, Helena[Excerpt] Introduction The presence of non-starch polysaccharides (NSP) in most plant feedstuffs (PF) has been associated with adverse effects on carnivorous fish nutrient digestibility and, ultimately, on growth and health. The lack of enzymatic machinery and well-developed microbiota in the digestive tract of carnivorous fish for processing NSP are possible causes for such effects. A promising nutritional str...
Production of enzymatic extracts for aquafeeds by solid-state fermentation with...
Filipe, Diogo; Salgado, José Manuel Seara; Fernandes, Helena; Castro, C.; Belo, Isabel; Aires, T.; Oliva-Teles, Aires; Moyano, Francisco J.[Excerpt] Introduction The replacement of fishmeal by plant ingredients in aquafeeds imposed new formulation strategies to overcome some nutritional restrictions associated with these alternative ingredients. Thus, supplementation of plant-based diets with feed additives, as exogenous enzymes and antioxidants compounds, has recently attracted increasing interest to improve feed utilization and to promote animal...
Effects of calcium carbonate inclusion in low fishmeal diets on growth, gastroi...
Parma, Luca; Yufera, Manuel; Navarro-Guillen, Carmen; Moyano, Francisco J.; Soverini, Matteo; D'Amico, Federica; Candela, Marco; Fontanillas, RamonFishmeal (FM) possesses one of the highest buffering capacities in comparison to most alternative vegetable aquafeed ingredients and its decreasing content in current formulations might affect the ideal gastrointestinal environment for digestive enzyme action and gut bacterial community of carnivorous fish species. A study was undertaken, therefore, to assess growth response, gastrointestinal pH, digestive enzy...
