Extract

The presence of soluble non-starch polysaccharides (SNSP) in non-ruminant diets can have a negative effect on digestibility due to the increase in digesta viscosity they invariably promote. Viscosity measurements studies have relied on supernatant viscosity following the removal of solid particles from the digesta via centrifugation. However, Takahashi and Sakata (2004) observed that the removal of solid particles from caecal contents changes the basic rheological characteristics of digesta from a non-Newtonian fluid to a Newtonian fluid. The aim of the current study was to investigate the effect of a SNSP source in piglet diets on whole digesta viscosity measurements as determined through a novel protocol developed at Nottingham.
