Purified non-starch polysaccharides (NSP) affect intestinal nutrient flow and hence microbial fermentation in pigs. Therefore, we investigated the effect of NSP differing in viscosity and fermentability on colonic fermentation and bacterial populations in eight ileal-cannulated barrows (BW 30 kg) fed a cornstarch-casein based diet supplemented with 5% low fermentable , low viscous cel lulose (C...

The objective of this study was to determine the effects of diets having different fermentability on blood gases, blood metabolites and ruminal fermentation parameters in Holstein dairy cows. Four multiparous Holstein dairy cows (665 ± 25 kg BW, 170 ± 7.0 DIM and 15±1.5 kg of milk yield), fitted with rumen cannulae, were used in a 4×4 Latin Square design with 28-d periods. Corn starch and sucro...

During the mashing process of brewing, activity of the amylolytic enzymes decays due to the high temperatures used to gelatinise the starch. Because the different enzymes produce different sugars, high temperatures can be exploited to modify the fermentability of resulting worts. This is especially useful when producing low alcohol beers. The expression a.exp(b.t)-c.exp(d.t) (where t is the tem...

Depending on type and inclusion level, dietary fibre may increase and maintain satiety and postpone the onset of hunger. This 7-week study evaluated the effect of fibre fermentability on physiological satiety-related metabolites and voluntary food intake (VFI) in dogs. Sixteen healthy adult dogs were fed a low-fermentable fibre (LFF) diet containing 8.5 % cellulose or a high-fermentable fibre (...

The sugar level, fermentability, and acceptability by voles of ryegrass straw treated with different acids were compared. Sugar release was highest with HCl, but acceptability was best with H(3)PO(4) treatment. Candida utilis grew about equally well on all of the treated samples, except the one treated with 0.5 N HCl. That sample supported no growth, possibly because the level of chloride or de...

This study was designed to compare the effects of dietary supplementation with nondigestible carbohydrates, differing in fermentability by colonic bacteria, on hepatic steatosis in growing obese Zucker rats. Male Zucker fa/fa rats were divided into three groups: a control group that received the basal diet, a fructan group that received 10 g highly fermented Synergy 1/100 g diet and a cellulose...

Objectives: The effects of trehalose on cariogenesis by mutans streptococci were investigated. Methods: Inhibited effect of trehalose on water-insoluble glucan (WIG) synthesis from sucrose by glucosyltransferase (GTase) of mutans streptococci was assayed. The acid fermentability of trehalose by mutans streptococci was determined by the measurements of pH, and amounts of lactic acid production. ...
