The aim of our work was to find the influence of combined biochemical additives on nutritive value and fermentation process of high moisture corn (HMC). In the experiment we used corn with high content of moisture, ranging from 608.9 to 613.3 g. After harvesting, corn was directly crimped on crusher. Two different variants of HMC were examined: K - untreated control and A - treated with combined additives containing lactic acid bacteria, enzymatic complex of cellulases and natrium benzoate. After six months the average samples were evaluated for content of nutrients and parameters of nutritive value. Addition of silage conservants decreased the content of crude fibre (p less than 0.01) through cellulases. Lactic acid bacteria had positive effect on starch content (p less than 0.01) and total saccharides (p less than 0.001). Quality of fermentation process affected the additives statistically, particularly in regards of significant lower content of acetic acid (p less than 0.05) and higher content of propionic acid (p less than 0.01) which has marked fungicidal characteristics. In silage of experimental variant A we found significantly lower value of pH (p less than 0.05).
