“…In pigs, inclusion of pea fibre in a wheat diet tended to increase the output of mucins in the ileal digesta from 6.1 to 7.3 g per day for diets supplemented with 0 and 240 g of pea fibre per day, respectively (Lien, Sauer, & He, 2001). Similarly ileal glucosamine and galactosamine excretion increased continuously with fibre intake (Reverter, Lundh, & Lindberg, 1999). When wheat bran (150 g/kg diet dry matter) was added to a protein-free diet for pigs, the ileal output of galactosamine at the terminal ileum increased from 1.93 to 4.13 g per day (Fuller & Cadenhead, 1991).…”
