Abstract:
Feed refused by swine contained a high-propagule density of Eurotium chevalieri Mangin (anamorph, Aspergillus chevalieri (Mangin) Thom and Church), Eurotium amstelodami Mangin (anamorph, Aspergillus amstelodami (Mangin Thom and Church), and Aspergillus candidus Link. Echinulin (8 micrograms/g of feed) was detected in the feed. Isolates of E. chevalieri and E. amstelodami but not A. candidus produced echinulin on rice or cracked corn. Mice refused to drink water containing 90 micrograms of echinulin per ml. This is the first report of the alkaloid echinulin in feed refused by swine.
