Abstract
Swine dysentery (SD) is a contagious mucohaemorrhagic diarrhoeal disease with severe impacts on production efficiency in grower/finisher pigs. The causative agent of SD is the intestinal spirochaete Brachyspira hyodysenteriae that induces inflammation and necrosis of the caecum and colon (Hampson et al., 2006). Recently, Thomsen et al. (2007) found that an organic diet containing sweet lupins and dried chicory root completely prevented SD following experimental challenge with B. hyodysenteriae. However, based on the study by Thomsen et al. (2007) it wasn’t possible to determine whether the dietary protection against SD was due to the galactans supplied by the sweet lupins or inulin from the dried chicory roots or if both carbohydrate sources are needed. It was hypothesised that diets (barley and triticale based) containing galactans (as lupins) and fructans (as inulin) could prevent the occurrence of swine dysentery (SD) after experimental infection with B. hyodysenteriae.
