The objective of this study was to determine the influence of artificial Fusarium contamination of maize on nutritive value and ensiling process. Silages were prepared from the Bt-hybrid MONSANTO MON 810 (Bt) and from the maize hybrid MONUMENTAL that was either untreated (C) or artificially inoculated with Fusarium strains (I). The inoculation was made in the growing crop at the end of flowering. Plants were harvested at soft dough stage of maturity and ensiled in microsilage tubes. Forage dry matter (DM) content differed significantly, being 362.2 g/kg in C, 375.8 g/kg in Bt and 350.7 g/kg in I. Forage I contained higher levels of deoxynivalenol (DON), fumonisins (FUM) and aflatoxin (AFL) than forage C or Bt (P less than 0.05). Content of DM of silages differed significantly, being 346.8 g/kg in C, 360.8 g/kg in Bt and 331.1 g/kg in I. Silage I had higher content of DON and FUM (P less than 0.05) than silage C and Bt.
