Spirulina and Chlorella vulgaris as ingredients in diet of weaned piglets : a v...
Martins, Cátia FalcãoABSTRACT - Worldwide swine production will face challenges in the coming years associated with feeding, mainly due to the high cost and environmental impact of importation of conventional feedstuffs. Therefore, the need for sustainable alternative feedstuffs is clear. Microalgae, due to their production systems, may be a sustainable alternative. However, their recalcitrant cell walls decrease nutrient bioavaila...
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...
Effect of dietary Spirulina (Arthrospira platensis) on the intestinal function ...
Martins, Cátia Falcão; Ribeiro, D. M.; Matzapetakis, Manolis; Pinho, Mário A.; Kuleš, Josipa; Horvatić, Anita; Guillemin, NicolasThe effect of dietary Spirulina (Arthrospira platensis) and CAZyme supplementation was assessed on the gut of weaned piglets, using an integrated NMR-metabolomics approach combined with Tandem Mass Tag labelled proteomics. Thirty weaned male piglets were assigned to one of the three following diets (n = 10): cereal and soybean meal basal diet (Control), basal diet with 10% Spirulina inclusion (SP) and SP diet s...
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...
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...
Dietary Arthrospira platensis improves systemic antioxidant potential and chang...
Madeira, Marta Sofia Morgado dos Santos; Lopes, Paula Alexandra Antunes Brás; Martins, Cátia Falcão; Assunção, José Miguel PestanaBackground: The ability of a high level of dietary Arthrospira platensis, individually or in combination with two exogenous carbohydrate-degrading enzymes (lysozyme and Rovabio®), to improve systemic antioxidant potential and hepatic lipid metabolism was tested in piglets. Forty male post-weaned piglets, sons of Large White × Landrace sows crossed with Pietrain boars, were allocated into 4 groups (n = 10) and f...
Influence of dietary Spirulin inclusion and lysozyme supplementation on the lon...
Ribeiro, D. M.; Martins, Cátia Falcão; Kules, Josipa; Horvatic, Anita; Guillemin, Nicolas; Freire, João; Eckersall, P. David; Almeida, AndréArthrospira platensis (Spirulina) is a microalga with a high content of crude protein. It has a recalcitrant cell wall that limits the accessibility of the animal endogenous enzymes to its intracellular nutrients. Enzymatic supplementation aiming to degrade cell walls could benefit microalgae digestibility. The objective of this study was to evaluate the impact of dietary Spirulina and lysozyme supplementation ...
Influence of dietary supplementation with an amino acid mixture on inflammatory...
Prates, José A.M; Freire, João; Almeida, André; Martins, Cátia Falcão; Ribeiro, David M.; Osorio, Hugo; Pinho, Mário; Lopes, Paula AlexandraIn order to investigate the effect of a dietary amino acid mixture supplementation in lipopolysaccharide (LPS)-challenged weaned piglets, twenty-seven 28-day-old (8.2 ± 1.0 kg) newly weaned piglets were randomly allocated to one of three experimental treatments for five weeks. Diet 1: a CTRL treatment. Diet 2: an LPS treatment, where piglets were intraperitoneally administered LPS (25 μg/kg) on day 7. Diet 3: a...
