The effects of two commercial enzyme products on the nutritive value of canola meal (CM) and sunflower meal (SFM) were determined in a classical AME bioassay with special emphasis on the utilization of nonstarch polysaccharides (NSP). The enzymes were added to semi-purified broiler grower diets based on corn and casein containing 35% CM or 35% SFM,(More)
1. A study was undertaken to evaluate the effects of mannanoligosaccharide (MOS, Bio-MOS, Alltech Inc.) on the growth performance, energy utilisation, nutrient digestibility and intestinal microflora of birds given a sorghum-wheat based diet. Two MOS levels (1 and 2 g/kg) were included in the diet. 2. Inclusion of MOS at both levels in the diet improved the(More)
1. A 3 × 2 factorial experimental design was used to investigate the interaction between threonine concentration (0.70, 1.0 and 1.3 of National Research Council (NRC), 1994, recommendations) and manno-oligosaccharides (0 and 2 g/kg) on feed passage rate in relation to intestinal microbial activities and crude mucin turnover. 2. There was no interaction(More)
A feeding trial was conducted to evaluate the effects of mannanoligosaccharide (MOS) on the growth performance, nutrient digestibility and gut development of broilers given a corn or a wheat-based diet over a 21-day experimental period. Dietary MOS improved the growth performance of birds given the wheat-based diet compared to that of birds given the(More)
1. The effects of two enzyme products on the nutritive value of soyabean meal (SBM) were investigated with the emphasis on changes in composition of non-starch polysaccharides (NSP) along the digestive tract. Enzyme A was a commercially available product containing mainly hemicellulase, pectinase, beta-glucanase and some protease activities and Enzyme B was(More)
1. An experiment was conducted to characterise and evaluate, in comparison to zinc bacitracin (ZnB), the response of intestinal microflora and mucins to manno-oligosacchares (MOS, Bio-MOS(R), Alltech Biotechnology, Nicholasville, Kentucky, USA). 2. Supplementation of MOS and ZnB selectively increased the intensity of sulphomucins. As revealed by the plate(More)
Three xylanase products, xylanase A derived from Thermomyces lanuginosus, xylanase B from Humicola insolens and xylanase C from Aspergillus aculeatus, were examined for their effects on the nutritive value of wheat. The study investigated the effects of enzyme addition to broiler diets based on a low-metabolisable-energy (ME) wheat and a normal-ME wheat,(More)
1. The effects of mannanoligosaccharide (MOS, Bio-Mos, Alltech Inc.) on the growth performance and digestive system, particularly gut microflora, were tested and compared with fructooligosaccharide (FOS, Raftilose P95, Orafti) using 1-d-old birds in an Escherichia coli challenge model. The experiment lasted for 3 weeks and zinc bacitracin (ZnB) was used as(More)
1. The effects of 3 commercial enzyme products on the nutritive value of 2 lupin species were investigated with the emphasis on changes in composition of non-starch polysaccharides (NSPs) along the digestive tract. Enzyme A contained primarily cellulase, beta-glucanase and xylanase activities, enzyme B primarily hemicellulase, pentosanase and xylanase(More)
1. A 3 × 2 factorial experimental design was used to investigate the interaction between threonine concentration (0.7, 1.0 and 1.3 of National Research Council (NRC), 1994, recommendations) and manno-oligosaccharides (MOS) supplemented at 0 and 2 g/kg on growth performance in relation to intestinal flow of crude mucins, mucosal development and nutrient(More)
