Introduction: Among farm animals, pigs are known to respond most sensitive to DON contaminated feed. The most important source of DON exposure is cereal grain mixed into the diet. However, it is possible that pigs are additionally exposed via straw used as bedding material or as feedstuff. DON from fibre rich plant materials is frequently thought to be bound to plant cell wall components and could consequently be available only to a limited extend for the monogastric pig. Thus, the aim of the present experiment was to scrutinize the bioavailability of DON from straw and chaff in comparison to grain.Conclusion: The higher bioavailability of DON from straw compared to grain might suggest that DON from this fibre rich material is available for the animal, but not detectable by routine DON analysis. Thus, there is a need to proof these methods for straw and perhaps also for other feed with high fibre concentrations
