Occurrence of the fusariumtoxins deoxynivalenol and zearalenone in Austrian feedstuffs in the period of 1995 to 1999.

3970 feed samples were analysed for the fusariumtoxins deoxynivalenol and z earalenone. 979 (24.6 %) of the submitted feed samples from farms with case history (swine herds: decreased feed intake and daily weight gain, vomitin g, cannibalism, impaired fertility, small litter size, weakness of newborn piglets, prolonged oestrus of sows; cattle: persistence of follicular ovari an cysts, enteritis, decreased slaughter weight, feed refusal). 74 % of the samples contained cereal and corn ingredients respectively or were complet e diet samples from swine herds. Based on economic losses the fusariumtoxin deoxynivalenol is most important in Austrian husbandry and particularly fo und in maize, cornsilage, wheat and oat.
