Xylo-oligosaccharides display a prebiotic activity when used to supplement whea...
Ribeiro, T.; Cardoso, V.; Ferreira, L. M. A.; Lordelo, M. M. S.; Coelho, E.; Moreira, A. S. P.; Domingues, M. R. M.; Coimbra, M. A.; Bedford, M. R.It is now well established that exogenous β-1,4-xylanases improve the nutritive value of wheat-based diets for poultry. Among other factors, the mechanism of action of exogenous enzymes may involve a microbial route resulting from the generation of prebiotic xylo-oligosaccharides (XOS) in the birds' gastro-intestinal (GI) tract. In a series of three experiments, the effect of XOS on the performance of broilers ...

Pasture intake improves the performance and meat sensory attributes of free-ran...
Ponte, Patrícia I. P.; Rosado, C. M. C.; Crespo, J. P.; Crespo, D. G.; Chaveiro-Soares, Manuel António; Mendes, I.; Gama, L. T.Free-range chickens are assumed to consume low to moderate levels of pasture, although the effects of forage intake in broiler performance and poultry meat quality remain to be established. In addition, despite cellulases and hemicellulases being widely used as feed supplements to improve the nutritive value of cereal-based diets for fast-growing broilers, the potential interest of these biocatalysts in the pro...
Improving the lipid nutritive value of poultry meat through the incorporation o...
Ponte, Patrícia I. P.; Prates, José António Mestre; Crespo, J. P.; Crespo, D. G.; Alves, S. P.; Bessa, Rui José Branquinho deDehydrated forages are assumed to be good sources of α-linolenic acid (ALA) and lipid-soluble antioxidant compounds (vitamin E homologs and β-carotene). The effects of including a dehydrated leguminous-based forage in a typical diet for broiler chicken, on performance, meat quality, and fatty acid composition were evaluated. One hundred sixty 1-d-old male commercial broiler chicks (Ross 308) were housed in 20 b...
Restricting the intake of a cereal-based feed in free range pastured poultry: e...
Ponte, Patrícia I. P.; Prates, José António Mestre; Crespo, J. P.; Crespo, D. G.; Alves, S. P.; Bessa, Rui José Branquinho dePastures are assumed to be good sources of α-linolenic acid (ALA) and other bioactive compounds. In this study, we evaluated the effects of restricting the intake of a cereal-based feed on the consumption of a legume-based pasture, and consequently on poultry performance and meat quality. Broilers of the RedBro Cou Nu × RedBro M genotype were fed a cereal-based feed at different intake restriction levels (100, ...
Effect of dietary dehydrated pasture and citrus pulp on the performance and mea...
Prates, José António Mestre; Bessa, Rui José Branquinho de; Ferreira, L. M. A.; Fontes, Carlos M. G. A.; Ponte, Patrícia I. P.; Mourão, J. L.Some feedstuffs containing significant levels of fiber may be a good source of bioactive compounds that may contribute to improving broiler meat quality. However, high fiber level can have a negative impact on broiler performance. A study was undertaken to investigate the impact of incorporating citrus pulp (5 or 10%) or dehydrated pasture (5 or 10%) on the performance, carcass yield, and characteristics of bro...
Use of ß-glucanases and ß-1,4-xylanases to supplement diets containing alfalfa ...
Ponte, Patrícia I. P.; Prates, José António Mestre; Centeno, Maria de São José Sousa Deyrieux; Ferreira, L. M. A.; Chaveiro-Soares, Manuel AntónioIt is well established that the use of alfalfa in diets for monogastric animals is limited by its high fiber content. However, alfalfa is a natural source of xanthophylls and gives poultry products a desirably yellow color. In addition, alfalfa saponins may contribute to reduce the levels of cholesterol in the meat and egg yolk. We have investigated the potential utilization of β-glucanases and β-1,4-xylanases ...
Produção de frangos de carne em pastagens à base de Leguminosas
Ponte, Patrícia I. P.; Rosado, C. M. C.; Crespo, J. P.; Crespo, D. G.; Chaveiro-Soares, Manuel António; Mendes, I.; Gama, L. T.Portugal apresenta reconhecidas potencialidades edafoclimáticas para a produção de pastagens à base de leguminosas, tanto em condições de regadio como de sequeiro. Este trabalho pretendeu avaliar a possibilidade de desenvolver formas alternativas para a produção de frangos de carne em pastagens. Avaliou-se o desempenho produtivo de frangos RedBro Cou Nu x RedBro M mantidos dos 28 aos 56 dias em pastagens de seq...
