Abstract

Lupins contain high levels of non-starch polysaccharides (NSP) both in hulls and kernels, suggesting complex associations between digestible nutrients and these structural NSP in kernels. Therefore, the degree of mechanical grinding could influence digestibility of dietary components. Hammer-milling lupins through a finer screen (3 vs. 5mm) increased total tract digestibility (TTD) of energy by 5% and digestible energy (DE) content by 1 MJ/kg (Wigan et al., 1995). However, associations between TTD of nutrients and the lupin particle size have not been investigated in detail. The aim of this study was to establish relationships between particle size of lupins and TTAD of dietary components in growing pigs.
