Effects of dietary fibre source and enzyme supplementation on faecal apparent d...
Carneiro, M.S.C.; Lordelo, M.M.; Cunha, L.F.; Freire, J.P.B.The effects of fibre source, either wheat bran (WB) or maize cobs (MC), and dietary exogenous enzymes (ES) on performance and digestive parameters of weaned piglets were studied in 24 Duroc×Landrace male piglets, weaned at 21 days of age. There were four treatments arranged factorially, with two sources of fibre (WB or MC) and two concentrations of ES (0 or 0.15 g/kg) that contained 800 U/kg of endo-1,4- -cellu...
Isoleucine and valine supplementation of a low-protein corn-wheat-soybean meal-...
Lordelo, M.M.; Gaspar, A.M.; Le Bellego, L.; Freire, J.P.B.The effects of Ile and Val supplementation of a low-CP, corn-wheat-soybean meal-based piglet diet on growth performance, incidence of diarrhea, and N balance were studied using 60 Landrace × Duroc male piglets in a 4-wk experiment. The 60 individually caged piglets were divided into 5 dietary treatments, each consisting of 12 piglets. Diet 1 was a positive control diet (20% CP); diet 2 was a low-CP negative con...
Role of a family 11 carbohydrate-binding module in the function of a recombinan...
Lordelo, M.M.; Guerreiro, C.I.P.D.; Ribeiro, T.; Ponte, P.I.P.; Falcão, L.; Freire, J.P.B.; Ferreira, L.M.A.; Prates, J.A.M.; Fontes, C.M.G.A.Cellulases and xylanases display a modular architecture that comprises a catalytic module linked to one or more non-catalytic carbohydrate-binding modules (CBMs). CBMs have been classified into 52 different families, based on primary structure similarity. These non-catalytic modules mediate a prolonged and intimate contact of the enzyme with the target substrate eliciting efficient hydrolysis of the target poly...

Lordelo, M.M.; Ribeiro, T.; Ponte, P.I.P.; Guerreiro, C.I.P.D.; Santos, H.M.; Falcão, L.; Freire, J.P.B.; Ferreira, L.M.A.; Prates, J.A.M.1. Exogenous microbial -1,3-1,4-glucanases and hemicellulases contribute to improving the nutritive value of cereals rich in soluble non-starch polysaccharides for poultry. 2. In general, plant cell wall hydrolases display a modular structure comprising a catalytic module linked to one or more non-catalytic carbohydrate-binding modules (CBMs). Based on primary structure similarity, CBMs have been classified in...
Effect of prebiotic or probiotic supplementation and ileo rectal anastomosis on...
Marinho, M.C.; Pinhob, M.A.; Mascarenhas, R.D.; Capela e Silva, Fernando; Lordelo, M.M.; L.F. Cunha, L.F.; Freire, J.P.B.Forty eight 21 days old piglets were used to compare the effect of prebiotic or probiotic supplementation and ileo rectal anastomosis on the morphology of the small intestine. Half of the piglets were maintained intact and the other half was subjected to an ileo rectal anastomosis (IRA). Each group of piglets received one of the following diets: 1) basal diet (C), 2) basal diet supplemented with a Xylo-oligosac...
Microbial activity in the gut of piglets: effect of fibre source and enzyme sup...
Lordelo, M.M.; Carneiro, M.; Cunha, L.F.; Freire, J.P.B.Twenty four Duroc×Landrace male piglets, aged 21 days, were assigned to 1 of 4 experimental diets. Diets 1 and 2 contained 150 g kg−1 wheat bran and diets 3 and 4 contained 90 g kg−1 maize cobs as the major fibre source. All diets contained 480 g kg−1 wheat and 200 g kg−1 soybean meal. Diets 2 and 4 were supplemented with the following enzyme complex: 800 U/kg cellulase, 1800 U/kg glucanase and 2600 U/kg xylana...
Microbial activity in the gut of piglets: effect of prebiotic and probiotic sup...
Lordelo, M.M.; Marinho, M.C.; Cunha, L.F.; Freire, J.P.B.Four groups of six 21 days-old piglets were used to evaluate the effect of a prebiotic or probiotic on the intestinal fermentative activity. In each group, piglets received one of the following diets: basal diet (C); basal diet supplemented with xylooligosaccharide (C-XOS); basal diet supplemented with Saccharomyces cerevisiae (C-SC); and basal diet supplemented with xylooligosaccharide and S. cerevisiae (C-XOS...

Chapter 41. Faecal and ileal digestibility of casein- and soybean-based diets i...
Martins, J.M.; Abreu, M.C. de; Bento, O.; Salgado, P.; Freire, J.P.B.A study was conducted to determine the effects of ileo-rectal anastomosis (IR) and protein source on apparent digestibility in growing pigs. Intact animals fed casein diet had significantly higher CP and NDF digestibilities than IR pigs. Intact animals fed soybean diet presented significantly higher DM, OM, CP, NDF, ADF and GE digestibilities than IR pigs. Intact pigs fed casein diet presented significantly hig...
