Impact of high Spirulina diet, extruded or supplemented with enzymes, on blood ...
Spínola, Maria P.; Alfaia, Cristina M.; Costa, Mónica M.; Pinto, Rui M. A.; Lopes, Paula A.; Pestana, José M.; Tavares, João C.; Mendes, Ana R.The impact of 15% dietary inclusion of Spirulina (Arthrospira platensis) in broiler chickens was explored, focusing on blood cellular components, systemic metabolites and hepatic lipid and mineral composition. From days 14 to 35 of age, 120 broiler chickens were divided and allocated into four dietary treatments: a standard corn and soybean meal-based diet (control), a 15% Spirulina diet, a 15% extruded Spiruli...
Effects of high dietary inclusion of Arthrospira platensis, either extruded or ...
Costa, Mónica M.; Spínola, Maria P.; Tavares, Beatriz; Pestana, José M.; Tavares, João C.; Martins, Cátia F.; Alfaia, Cristina M.; Carvalho, DanielaBackground This investigation assessed the effects of high dietary inclusion of Spirulina (Arthrospira platensis) on broiler chicken growth performance, meat quality and nutritional attributes. For this, 120 male broiler chicks were housed in 40 battery brooders (three birds per brooder). Initially, for 14 days, a standard corn and soybean meal diet was administered. Subsequently, from days 14 to 35, chicks wer...
Enhancing meat quality of weaned piglets with the dietary incorporation of Ulva...
Pestana, José M.; Alfaia, Cristina M.; Ribeiro, David Miguel; Costa, Mónica M.; Carvalho, Daniela F.P.; Martins, Cátia F.; Alves, Victor M.D.The impact of the dietary incorporation of 7% Ulva lactuca, a green seaweed, on the quality and nutritional value of piglet’s meat was assessed. U. lactuca is rich in nutrients and bioactive compounds but its cell wall is composed of complex polysaccharides that reduce their bioavailability. Therefore, the effect of supplementing piglet diets with exogenous carbohydrases was also assessed here. A total of 40 ma...
Dietary Ulva lactuca and CAZyme supplementation improve serum biochemical profi...
Ribeiro, David M.; Lopes, Paula A.; Pinto, Rui M. A.; Pestana, José M.; Costa, Mónica M.; Alfaia, Cristina M.; Mourato, Miguel; Almeida, AndréUlva lactuca is a seaweed with antinutritional cell wall for monogastrics. Carbohydrate-Active enZymes (CAZymes) supplementation can potentially cause its disruption. This study evaluates four diets: Ctrl—control diet; UL—control + 7% U. lactuca (wild caught, powdered form); ULR—UL + 0.005% Rovabio® Excel AP; ULU—UL + 0.01% ulvan lyase on piglets’ haematologic and serologic profiles, hepatic lipids and minerals...
Combination of Mechanical/Physical Pretreatments with Trypsin or Pancreatin on ...
Costa, Mónica M.; Spínola, Maria P.; Prates, José A.MABSTRACT - Arthrospira platensis contains high protein content and quality, which makes it a promising feed source for livestock animals. However, this microalga presents a recalcitrant peptidoglycan cell wall, and its main proteins form protein-pigment complexes attached to the algal thylakoid membrane. The purpose of the present study was to evaluate the effect of mechanical/physical pretreatments (bead milli...

Effect of Laminaria digitata dietary inclusion and CAZyme supplementation on bl...
Ribeiro, David M.; Pinto, Rui M. A.; Lopes, Paula A.; Pestana, José M.; Alfaia, Cristina M.; Costa, Mónica M.; Carvalho, Daniela F. P.; Mourato, MiguelSeaweeds, such as Laminaria digitata, are a sustainable alternative to conventional feedstuffs for weaned piglet diets, improving their health and mitigating environmental impacts. L. digitata has a complex cell wall that can be difficult for monogastrics to digest. However, carbohydrate-active enzymes (CAZymes) such as Rovabio® Excel AP and alginate lyase can help break down these polysaccharides and render in...
Studies on the impact of selected pretreatments on protein solubility of Arthro...
Spínola, Maria P.; Costa, Mónica M.; Prates, José A.MArthrospira platensis has emerged as a novel protein feed source since it contains high protein level and quality. However, this microalga presents a recalcitrant cell wall and its main proteins form protein-pigment complexes attached to the thylakoid membrane. The objective of the present study was to evaluate the influence of mechanical/physical pretreatments (bead milling, extrusion, freeze-drying, heating, ...
Effect of Dietary Laminaria digitata with Carbohydrases on Broiler Production P...
Costa, Mónica M.; Pestana, José M.; Osório, Diogo; Alfaia, Cristina M.; Martins, Cátia F.; Mourato, Miguel; Gueifão, Sandra; Rego, Andreia M.Simple Summary: Seaweeds represent promising alternatives to unsustainable conventional feed sources, such as cereals, incorporated in poultry diets. Brown macroalgae (e.g., Laminaria digitata) correspond to the largest cultured algal biomass worldwide and are rich in bioactive polysaccharides, minerals, and antioxidant pigments. However, their utilization as feed ingredients is limited due to the presence of a...
Effect on Broiler Production Performance and Meat Quality of Feeding Ulva lactu...
Costa, Mónica M.; Pestana, José M.; Carvalho, Patrícia; Alfaia, Cristina M.; Martins, Cátia F.; Carvalho, Daniela; Mourato, Miguel; Gueifão, SandraSIMPLE SUMMARY: Macroalgae have been increasingly exploited worldwide for feed, food and biofuel applications, due to their nutritive and bioactive compounds. Green seaweeds belonging to the genus Ulva have high growth rates, which makes them suitable for being cultured in sustainable algae production, such as an integrated multi-trophic aquaculture system. This is expected to increase the use of Ulva sp. as an...
