Silages from meadow grasses, produced in ecological farms which do not employ mineral fertilizers, are characterized by a low content of calcium, phosphorus, magnesium, manganese, zinc and beta-carotene as compared to the requirements of the ruminants. The preparations of lactic acid bacteria were utilized as biological substances which strengthen natural cycle of lactic fermentation, and mineral-vitamin additives were employed for enrichment of the silages' composition. Starter culture of the administrated preparation Lactosil, consisted of conventional (genetically non-modified) bacterial strains from species: Lactobacillus plantarum, Lactobacillus buchneri and Lactobacillus brevis, being isolated from natural plant environment. In ecological farms, experimental silages from meadow grasses, produced with the participation of Lactosil, supplemented with the mineral-vitamin mixture, were characterized by higher nutritional value, very good evaluation of quality, higher calcium content by 26 percent, and higher level of zinc by 75 percent, manganese by 38 percent, phosphorus by 86 percent, magnesium by 73 percent, with somewhat increased level of carotenoids by 27 percent, and longer by 9-11 days oxygen stability, as compared to the silages without the additives stimulating fermentation process
