Abstract
The influence of bacterial additive on concentration of mycotoxins in mixture silages of faba bean, oat and alfalfa with high dry matter content was studied. The fresh stuff was harvested in pods formation stage of faba bean and after considerable wilting it was cut in to 20 mm particles and stuffed into silage bags. We ensiled the mixture in the control variant without additives and in the trial variant with liquid additive with following biological constituents: Lactobacillus paracasei, Lactobacillus lactis, Pedioccus acidilacti at a dose of 0.5 liter per ton. The samples were examined for the nutritive value and mycotoxins content (deoxynivalenol, T-2 toxin, zearalenone and total fumonisins, ochratoxins) by direct competitive enzyme-linked immunosorbent assay. Zearalenone was the secondary metabolite of microscopic fungi with the highest concentration. This study suggests that application of bacterial additive can significantly reduce the concentration of zearalenone and total fumonisins in mixture silages of faba bean, oat and alfalfa.
