Fatty acids, selenium, and vitamin B12 in chub mackerel (Scomber colias) as nou...
Afonso, Cláudia; Cardoso, Carlod; Gomes-Bispo, Ana; Ferreira, Inês; Rego, Andreia; Motta, Carla; Prates, José A.M; Castanheira, IsabelChub mackerel (Scomber colias) is an underutilised fish abundant in the North Atlantic and a nutritious food with high docosahexaenoic acid (DHA), selenium (Se), and vitamin B12 contents, affected by seasonality. Hence, the bioaccessibility of fatty acid (FA), Se, and vitamin B12 in chub mackerel was studied. Daily consumptions of 51 g, 35 g, and 14 g of March, June, and October chub mackerel, respectively, wou...
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...
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, ...
Infuence of Chlorella vulgaris on growth, digestibility and gut morphology and ...
Martins, Cátia Falcão; Trevisi, Paolo; Coelho, Diogo F.; Correa, Federico; Ribeiro, David M.; Pinho, Mario; Pestana, Jose M.; Mourato, Miguel P.The purpose of this study was to evaluate the impact of Chlorella vulgaris (5% in the diet), supplemented or not with two exogenous carbohydrase mixtures on piglets’ performance, nutrient digestibility and gut morphology, fermentation products and microbiota. Forty-four male piglets weaned at 28 days of age, with 11.2 ± 0.46 kg of live weight, were used and assigned to 1 of 4 dietary treatments: cereal and soyb...
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...
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...
Impact of dietary Chlorella vulgaris and carbohydrate-active enzymes incorporat...
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...
Glutamine and cystine-enriched diets modulate aquaporins gene expression in the...
da Silva, Inês V.; Soares, Bárbara P.; Pimpão, Catarina; Pinto, Rui M. A.; Costa, Teresa; Freire, João P. B.; Corrent, EtienneABSTRACT - The regulation of glycerol permeability in the gastrointestinal tract is crucial to control fat deposition, lipolysis and gluconeogenesis. Knowing that the amino acid glutamine is a physiological regulator of gluconeogenesis, whereas cystine promotes adiposity, herein we investigated the effects of dietary supplementation with glutamine and cystine on the serum biochemical parameters of piglets fed o...
