The effect of two preservatives (formic and sulphuric acid) on the quality of alfalfa silage, has been studied. The tested preservatives were used in various doses. There was a highly significant difference between silage with and without preservatives in the degree of sourness, the NH3-N percentage and the butyric and acid content. There was a significant difference in the content of NH3-N and ph between silage with 5 l/t of formic acid and 3 l/t sulphuric acid, to the advantage of the former. The level of dry matter had a highly significant effect on the formation of acetic acid and ammoniacal nitrogen. The best grade, between first and second class, was given to silage preserved in formic acid of 5 l/t. Silage preserved with formic acid of 3 l/t was second class, while silage with sulphuric acid of 5 l and 3 l/t of green mass was also second class although somewhat poorer. Silage without preservatives was placed in the fifth class.
