MYCOTOXIN CONTAMINATION OF MEADOW GRASSES IN EUROPEAN RUSSIA
A toxicity of plants eaten by animals at grazing land is shown to be complicated with various causes and clinical manifestations. In addition to phytotoxins and «infection» factors carried onto the plants by the insects (e.g., bacterial corynetoxins), the toxic metabolites of endophytic and epiphytic fungi are considered to play the significant role. Based on early understanding, the local risks for cattle, sheep and horses during grazing and stable periods were caused mainly by ergotism, myrothecio- and fusariotoxicoses. Then, for a long time a mycotoxicological evaluation of local grass feeds was not carried out. To date, there is the only one study indicating differences between contaminations of the wild-growing gramineous plants and cultivated cereal crops (A.A. Burkin et al., 2010). The aim of the paper was to summarize our data of assaing 517 meadow grass samples from natural pastures and haying places in European Russia undertaken for the first time to determine contamination with mycotoxins.
