Moulds are a big feed hygienic problem in animal husbandry. Beside
Penicillium roqueforti,
Monascus ruber and the family of the Mucoraceae,
Aspergillus fumigatus is an important contaminant of silage fodder.
Aspergillus fumigatus produces a wide variety of secondary metabolites, which are acting toxic, at least in part. There is only little information available about the occurrence of these metabolites in silages, one reason is the lack of reference substances. By isolation of reference substances from cultural extracts, 11 substances could be measured quantitatively, further 23 qualitatively. The investigation shows, that silage can be contaminated with a multiplicity of secondary A. fumigatus-metabolites. For economical reasons and particularly for the protection of animals and consumers, farmers have to prevent silage from mould growth.
