The main goal of this thesis was to evaluate the influence of additives on the qualitative indicators of grass silage. The evaluation concentrated in particular on lactic acid, pH and the degree of proteolysis. The selected qualitative indicators were monitored in 36 samples of grass silage from the region of South Bohemia. Silage samples were divided into three groups. The first group was a guide sample without any additives. The second group was treated with bacterial additives and the third group with bacteria-enzyme additives. Classification of silage samples was done according to "Norma 2004". Each sample was evaluated in terms of quality of fermentation and the content of nutrients. Statistically significant differences (p <0.05) were found in the content of lactic acid, pH and the degree of proteolysis between the group of silages without additives and the group treated with silage additives.
