Preservation of green mass of plants is an ancient method, which was used to preserve the nutritional value of feed in hermetic conditions. Enzymatic processes in the green mass of plants occur in a natural way due to the epiphytic microflora, which under anaerobic conditions begin to actively multiply and produce lactic acid. This acid is a good natural preservative, which lowers the pH of the medium to the acidic side (up to 3.8-4.2), contributing to a decrease in the vital activity of pathogenic microflora, thereby positively affecting the quality of canned voluminous juicy feed. Currently, in the world practice in the procurement of voluminous succulent feeds, various preservatives are actively used in combination with the withering of the green mass of plants. At the same time, the economic effectiveness of their use depends on external factors, moisture and chemical composition of phytomass, the cost of preservatives used. In this regard, this article considers a comparative assessment of the effectiveness of the influence of various biologics in preserving the green mass of alfalfa, as domestic production (Ferbak-Sil (Kazan), Bioamid-3 (Saratov), Biotroph (St. Petersburg) and the foreign one (Sil-Oll (Great Britain)) under laboratory conditions, the positive effect of biological preparations on the preservation of nutrients was established. Among the tested preservatives, Biotrof biological preparation distinguished itself stimulated in the biomass of lactic fermentation, which in turn had a positive impact on the preservation of dry matter, crude protein and metabolizable energy, whose performance has been higher than the control at 7.58%, 6.64% and 5.56%.
