Lucerne of the 5^th cut in the budding phase was ensiled in the experiment as fresh and wilted (DM= 220 and 360 g/kg), with two degrees of compression (520 and 380 g/dm³) and with added Min-a-zel plus as 2 g/kg green mass. The experiment was performed as the statistical model 2^K. Min-a-zel plus used as 2 g/kg green mass had no influence on biochemical, microbiological and mycotoxicological parameters of lucerne silage. Compared to the beginning material, silages had more diverse microflora and more mycotoxins.
