The occurrence of Fusarium strains and their mycotoxins in corn silage. 4. The occurrence of zearalenone in the first cut zone of horizontal silos

Studies of the occurrence of zearalenone in the cutting surface of a horizontal silo were carried out over 12 days. On all sampling days the silage contained less than 0.1 mg/kg zearalenone (detection limit of the thin-layer chromatographic procedure). Zearalenone could not be detected in silage put into interim store over a period of 17 days either. The results document that zearalenone-producing Fusarium species have no considerable share in the decay of maize silage.
