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.

摘要

被猪拒绝的饲料含有高繁殖体密度的谢瓦曲霉（无性型为谢瓦氏曲霉）、阿姆斯特丹曲霉（无性型为阿姆斯特丹曲霉）和亮白曲霉。在饲料中检测到了棘霉素（每克饲料8微克）。谢瓦曲霉和阿姆斯特丹曲霉的分离株而非亮白曲霉在大米或碎玉米上产生了棘霉素。小鼠拒绝饮用每毫升含有90微克棘霉素的水。这是关于猪拒绝的饲料中存在生物碱棘霉素的首次报道。
