Wheat β-based diet supplemented with a purified source ofβ -glucans had a considerably higher Coefficient of total tract apparent digestibility of gross energy and Nitrogen compared with barley β-based diets (Table 2). Therefore increased consumption of β-glucans may be achieved through provision of a purified β-glucan supplement, without associated implications for depressed energy and nutrient digestibility, as has been previously reported with barley β-based formulations (O’Connell et al., 2005; Lynch et al., 2007c).β-glucans have
