Occurrence and concentration of mycotoxins in grass silage from selected farms
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2019, Vol 64, Issue 3
Abstract
The aim of the study was to assess the frequency of occurrence and concentrations of mycotoxins in grass silages depending on meadow location, term of harvest and type of fertilizer used. The research material consisted of 24 grass silage samples collected in 2013 from three farms located in: Falenty, Kodeń and Kąty. The following mycotoxins were evaluated: deoxynivalenol (DON), nivalenol (NIV), T2 and HT2 toxin, zearalenone (ZEA) and roquefortine C (ROQ C). 22 samples were positive for at least one mycotoxin. The most frequently detected toxins were NIV (14 samples contaminated), DON and ZEA (10 samples). The concentration of mycotoxins in silage samples coming from individual farms varied and significant differences between farms were obtained only in the case of T2 toxin and ZEA. Silage made out of sward from the third cut was more likely to be contaminated, than silage made out of sward from the first cut. The type of fertilizer had no significant impact on mycotoxin concentrations except for NIV and HT2 toxin.
