The aim of this study was to determine the effect of different biological and biochemical additives on the final nutritive quality, fermentation process and concentration of mycotoxins of ensiled high moisture crimped corn. We created four variants for the experiment: control (UC), A1, and A2 (biological stimulators with the active principle of lactic acid bacteria) and variant B (combined additives with the active principle of lactic acid bacteria, benzoate sodium and active enzymatic complex of cellulases). After 6 months of storage in laboratory conditions, dry matter concentration ranged from 608.9 to 613 g/kg. In comparison with control, silages with additives were characterized by significantly lower concentrations of crude fibre and higher concentrations of nitrogen-free extract, total sugars and starch. The lowest concentration of acetic acid was determined in variant B, the lowest concentration of butyric acid in variant A1 and the lowest concentration of ammonia in variant B. We found lower concentrations of mycotoxins in treated than in control silages. In some cases, the differences were significant. In conclusion, silage additives influenced the nutritive and hygienic quality of the conserved fodders.
