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...
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...
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 incorporation of Chlorella vulgaris and CAZyme supplementatio...
Ribeiro, David M.; Coelho, Diogo; Osório, Hugo; Martins, Cátia; Freire, João; Almeida, João; Moreira, Olga; Almeida, André; Prates, José A.M.The combination of several factors, including an increase in world population and living standards in developing countries and world dependency on conventional crop imports drive a search for alternative feedstuffs for poultry and pig diets. This would reduce the environmental impact associated with the foreseeable increase in the demand for animal products. One of such alternatives are microalgae, a diverse gr...
Influence of dietary Spirulina inclusion and lysozyme supplementation on the lo...
Ribeiro, David M.; Martins, Cátia F.; Kules, Josipa; Horvatic, Anita; Guillemin, Nicolas; Freire, João; Eckersall, P. David; Almeida, André M.Arthrospira platensis (Spirulina) is a microalga with a high content of crude protein. Its recalcitrant cell wall 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 over the m...
Domestic animal proteomics in the 21st century: a global retrospective and view...
Almeida, André M.; Ali, Syed Azmal; Ceciliani, Fabrizio; Eckersall, P. David; Hernandez-Castellano, Lorenzo E.; Han, Rongwei; Hodnik, Jaka J.Animal production and health are of significant economic importance, particularly regarding the world food supply. Animal and veterinary sciences have evolved immensely in the past six decades, particularly in genetics, nutrition, housing, management and health. To address major challenges such as those posed by climate change or metabolic disorders, it is of utmost importance to use state-of-the-art research t...
Effects of Chlorella vulgaris as a feed ingredient on the quality and nutrition...
Martins, Cátia F.; Pestana, José M.; Alfaia, Cristina M.; Costa, Mónica; Ribeiro, David M.; Coelho, Diogo; Lopes, Paula A.; Almeida, André M.Chlorella 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...
A viewpoint on the use of microalgae as an alternative feedstuff in the context...
Chaves, Andreia A.M.; Martins, Cátia F.; Carvalho, Daniela F.P.; Ribeiro, David M.; Lordelo, Madalena; Almeida, André M.With the current increase in meat and animal products consumption, there is a need to make production systems more sustainable. The use of microalgae in monogastric feeds, replacing widely used conventional feedstuffs such corn and soybean, can be a solution to overcome this problem. Several studies have shown promising results in the use of microalgae in feeding of both pigs and poultry. However, there are sev...
Using microalgae as a sustainable feed resource to enhance quality and nutritio...
Martins, Cátia F.; Ribeiro, David M.; Costa, Mónica; Coelho, Diogo; Alfaia, Cristina M.; Lordelo, Madalena; Almeida, André; Freire, JoãoCereal grains and soybean meal are the main feedstuffs used in swine and poultry feeding, two of the most consumed meats and of key relevance to food security worldwide. Such crops are grown mostly in North and South America and transported over large distances creating sustainability concerns and, furthermore, are in direct competition with human nutrition. Alternatives to these ingredients are, thus, a pressi...
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...
