Influence of Feeding Weaned Piglets with Laminaria digitata on the Quality and ...
Ribeiro, David; Alfaia, Cristina; Pestana, José; Carvalho, Daniela; Costa, Mónica; Martins, Cátia; Lemos, José; Mourato, Miguel; Gueifão, SandraLaminaria 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...
Impact of Chlorella vulgaris as feed ingredient and carbohydrases on the health...
Coelho, Diogo; Alfaia, Cristina; Lopes, Paula Alexandra; Pestana, José M.; Costa, Monica M.; Pinto, Rui M.; Almeida, Joao M.; Moreira, OlgaThe implication of high dietary level of Chlorella vulgaris, individually and supplemented with two carbohydrase mixtures, on pigs' health and liver metabolism was assessed in this study. Forty crossbred (Large White × Landrace sows crossed with Pietrain boars) entire male pigs were randomly allocated to the following feeding treatments (n = 10): cereal-soybean meal basal diet (control); basal diet with 5% C. v...
Combined efects of dietary Laminaria digitata with alginate lyase on plasma met...
Costa, Mónica; Lopes, Paula Alexandra; Assunção, JMP; Alfaia, Cristina; Coelho, Diogo; Mourato, Miguel; Pinto, Rui; Lordelo, Maria; Prates, JAMABSTRACT - Background: The Laminaria digitata is an abundant macroalga and a sustainable feedstock for poultry nutrition. L. digitata is a good source of essential amino acids, carbohydrates and vitamins, including A, D, E, and K, as well as triacylglycerols and minerals, in particular iron and calcium. However, the few studies available in the literature with broilers document the application of this macroalga...
Recalcitrant cell wall of Ulva lactuca seaweed is degraded by a single ulvan ly...
Costa, Monica; Pio, Luís Bernardo; Bule, Pedro; Duarte, Marlene; Alfaia, Cristina; Coelho, Diogo; Bras, Joana; Fontes, Carlos M.G.A.; Prates, José A.MABSTRACT - Green macroalgae, e.g., Ulva lactuca, are valuable bioactive sources of nutrients; but algae recalcitrant cell walls, composed of a complex cross-linked matrix of polysaccharides, can compromise their utilization as feedstuffs for monogastric animals. This study aimed to evaluate the ability of pre-selected Carbohy- drate-Active enZymes (CAZymes) and sulfatases to degrade U. lactuca cell walls and re...
Effect of Dietary Laminaria digitata with Carbohydrases on Broiler Production P...
Costa, M.M.; Pestana, José; Osório, Diogo; Alfaia, Cristina; Martins, Cátia Falcão; Mourato, M.; Rego, Andreia; Lemos, J. P. C.; Fontes, Carlos M.G.A.ABSTRACT - 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® Exc...
Total lipids, fatty acid composition, total cholesterol and lipid-soluble antio...
da Silva, Jamile Andrea Rodrigues; Rodrigues, Laurena Silva; Lourenco-Junior, Jose de Brito; Alfaia, Cristina; Costa, Monica MendesThe aim of this study was to analyze the influence of distinct production systems and seasonal variation in the Brazilian Eastern Amazon on the meat lipid composition of water buffaloes. Water buffaloes were reared in commercial farms in the Eastern Amazon either in extensive systems (Marajó Island, Nova Timboteua and Santarém locations), during rainy or dry seasons, or intensive (feedlot) systems. Animals rear...

Coelho, Diogo; Alfaia, Cristina; Pestana, JMP; Costa, Mónica; Pinto, Rui; Fontes, Carlos M.G.A.; Lordelo, Madalena; Prates, José A.MBackground: Chlorella vulgaris has been proposed as a sustainable green feedstock in poultry nutrition due to its ease of cultivation, minimal environmental impact and balanced nutritional composition. However, the majority of studies documents the use of C. vulgaris as a dietary supplement in broilers instead of a feed ingredient. To the best of our knowledge, no report has shown the effect of a high-level inc...
Quality Traits and Nutritional Value of Pork and Poultry Meat from Animals Fed ...
Ribeiro, David Miguel; Martins, Cátia Falcão; Costa, Mónica; Coelho, Diogo; Pestana, José; Alfaia, Cristina; Lordelo, Madalena; Almeida, AndréSeaweeds have caught the attention of the scientific community in recent years. Their production can mitigate the negative impact of anthropogenic activity and their use in animal nutrition reduces the dependency on conventional crops such as maize and soybean meal. In the context of monogastric animals, novel approaches have made it possible to optimise their use in feed, namely polysaccharide extraction, biom...
Effects of Chlorella vulgaris as a feed ingredient on the quality and nutrition...
Martins, Cátia Falcão; Pestana, José M.; Alfaia, Cristina; Costa, Mónica; Ribeiro, D. M.; Coelho, Diogo; Lopes, Paula Alexandra; Almeida, AndréChlorella vulgaris (CH) is usually considered a feed supplement in pig nutrition, and its use as an ingredient is poorly studied. Among many interesting characteristics, this microalga has high protein levels and can be a putative alternative for soybean meal. Our aim was to study the effect of a 5% CH incorporation in the diet, individually or combined with two carbohydrases, on meat quality traits and nutriti...
