Crop beta-glucanase activity limits the effectiveness of a recombinant cellulas...
Ponte, Patricia; Lordelo, M.M.S; Chaveiro-Soares, Manuel M; Mourão, José Luís; Crespo, J.P; Crespo, D.G.; Gama, L.T.,; Ferreira, Luís; Prates, J.A.M.,1. The supplementation of diets rich in soluble polysaccharides with microbial cellulases and hemicellulases decreases digesta viscosity and promotes broiler performance. 2. In contrast, recent experiments suggest that polysaccharidases are ineffective for improving the nutritive value of pasture biomass used by free-range broilers. However, the feasibility of using cellulases and hemicellulases to improve the ...

Ponte, Patricia; Prates, J.A.M; Crespo, J.P.; Crespo, D.G.; Mourão, José Luís,; Alves, S.P; Bessa, J.B.; Chaveiro-Soares, M.A.; Ferreira, L.M.A.Dehydrated 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...
Pasture intake improves the performance and meat sensory attributes of free-ran...
Ponte, P.I.P; Rosado, C.M.C; Crespo, J.P.; Crespo, D.G; Mourão, José Luís; Chaveiro-Soares, M.A.; Mendes, I.L.T.; Gama, L.T.; Prates, J.A.M.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...
Restricting the intake of a cereal-based feed in free range pastured poultry: e...
Ponte, Patricia; Prates, J.A.M.; Crespo, J.P.; Crespo, D.G.; Mourão, José Luís; Alves, S.P.; Bessa, J.B.; Chaveiro-Soares, M.A.; Ferreira, L.M.A.Pastures 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, ...

Produção de frangos de carne em pastagens à base de Leguminosas
Ponte, P.I.P; Rosado, C.M.C; Crespo, J.P; Crespo, D.G; Chaveiro-Soares, M.A; Mourão, J.L; Mendes, I; Gama, L.T; Prates, J.A.M; Ferreira, L.M.APortugal 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 se...
