Feed grain production for on-farm use is widespread in Bavarian agriculture and garants a reliable production of healthy foodstuff. Therefore the quality of feed grain is very important for farmers. In an orientating investigation of the on-farm stored feed grain quality from the harvest years 1991 to 2000 1757 samples were analysed. Based on values for guidance by the German government for DON and ZEA and Commission Regulation EC No 472/2002 for OTA the results show that only 2% of the positive samples have amounts higher then 0,05 mg ZEA/kg grain, 4% of the positive samples contain more then 1 mg DON/kg grain and 2% of the positive samples have amounts higher then 0,003 mg OTA/kg feed grain. These illustrate the good conservation and storage quality on Bavarian farms.
