Experience in the use of modern biological preservatives in forage silage
The article presents the results of the analysis of the quality of canning and the preservation of nutrients of alfalfa haylage laid in dairy farms for 2016-2020 in the Republic of Bashkortostan. From the laboratory analyses we have obtained, we have identified the most useful preservatives that are available on the market of biological preparations. Among the effective biological preservatives, it is necessary to include preparations - "Bioamide-3", "SilactPro", which include propionic acid bacteria Propionibacterium sp in the composition of the drug. The use of these bioconservants provides an increase in the proportion of lactic acid from the total amount of acids -more than 68%, stabilization of the active acidity (pH) of the silage mass at the level of 4.6 pH for haylage, and an increase in energy value (NE) by 2.5-3.4%. Despite the proven effectiveness of the use of preservatives, compliance with the parameters and technology of silage remains a strict condition that determines not only guaranteed preservation, but also the quality of the haylage feed.
