Fusarium has been reported throughout western Canada. The principle toxin DON (deoxynivalenol or vomatoxin) contaminates the grain and impacts the feeding of pigs that ingest it. Average daily gain and feed intake are suppressed when fed DON levels over 1 to 2 ppm. Vomiting occurs at extremely high levels, over 20 ppm. Weanling pigs are more susceptible to the effect of DON and its impact on reproductive performance is unknown. It is important to take multiple samples of grain as DON is not evenly distributed throughout storage.
