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...

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...
Influence of Feeding Weaned Piglets with Laminaria digitata on the Quality and ...
Ribeiro, David Miguel; Alfaia, Cristina M.; Pestana, José M.; Carvalho, Daniela F.P.; Costa, Mónica; Martins, Cátia F.; Lemos, José P.C.Laminaria digitata is a novel feedstuff that can be used in pig diets to replace conventional feedstuffs. However, its resilient cell wall can prevent the monogastric digestive system from accessing intracellular nutrients. Carbohydrate-active enzyme (CAZyme) supplementation is a putative solution for this problem, degrading the cell wall during digestion. The objective of this work was to evaluate the effect o...
Plasma Metabolites and Liver Composition of Broilers in Response to Dietary Ulv...
Alfaia, Cristina M.; Costa, Mónica M.; Pinto, Rui M.A.; Pestana, José M.; Mourato, Miguel; Carvalho, Patrícia; Martins, Cátia F.; Lopes, Paula A.The effect of a high incorporation level of Ulva lactuca, individually and supplemented with a Carbohydrate-Active enZyme (CAZyme) on broilers’ plasma parameters and liver composition is assessed here. Twenty one-day-old Ross 308 male broilers were randomly assigned to one of four treatments (n = 10): corn/soybean meal based-diet (Control); based-diet with 15% U. lactuca (UL); UL diet with 0.005% of commercial ...

Costa, Mónica M.; Pestana, José M.; Osório, Diogo; Alfaia, Cristina M.; Martins, Cátia F.; Mourato, Miguel; Gueifão, Sandra; Rego, Andreia M.We hypothesized that dietary inclusion of 15% Laminaria digitata, supplemented or not with carbohydrases, could improve the nutritional value of poultry meat without impairing animal growth performance. A total of 120 22-day old broilers were fed the following dietary treatments (n = 10) for 14 days: cereal-based diet (control); control diet with 15% L. digitata (LA); LA diet with 0.005% Rovabio® Excel AP (LAR)...
