Extract

Non-starch polysaccharides (NSP) in cereals which have been linked to antinutritional activity through elevated viscosity of intestinal contents, vary in concentration in different regions of the grain, but are particularly rich in the endosperm cell wall (Forrest & Wainwright 1977; Mulder, Hotten et al 1991). The current trial investigated the degree to which increasing inclusion levels of an exogenous β-glucanase with different barley fractions, from either a hulled or known high viscosity producing hulless variety, would influence the viscosity of broiler digesta and if, as in rye (Bedford & Classen 1991), reductions in carbohydrate molecular weight were obtained.
