ЭФФЕКТИВНОСТЬ БИОЛОГИЧЕСКИХ ПРЕПАРАТОВ В КОНСЕРВИРОВАНИИ ЛЮЦЕРНЫ

Abstract

Preserving the green mass of plants is a complex technological process that depends on many factors: the population of epiphytic microflora, plant moisture, phase of plant development, sugar concentration in the grass mass, weather conditions, etc. Therefore, the quality of the resulting forage may be different. The usagee of various chemical and biological preservatives, recommended in recent years by many researchers, makes it possible to obtain high quality finished forage. The chemical preservatives (formic, propionic, benzoic acids, etc.) quickly acidify the herbal mass to the desired pH level (3.8 ... 4.2). But at the same time, one should not forget about the danger of harming these preservatives to the health of specialists, the environment and the corrosion properties of metal. In addition, they have a high cost. Therefore, in world practice, research is being conducted to find inexpensive, environmentally friendly and convenient to use biological products. These types include drugs, which include associated groups of lactic acid bacteria in a certain concentration with the aim of enhancing lactic acid fermentation in plant materials and preserving the nutritional value of the finished feed. In this regard, this article discusses a comparative assessment of the effectiveness of various biological preparations when preserving the dried green mass of alfalfa, both domestically produced Ferbac-Sil (Kazan) and foreign Sila Prime (Belarus) under laboratory conditions. During the study, a positive effect of the studied drugs on the safety of nutrients and energy was established. Among the tested preservatives, the biological preparation Ferbak-Sil distinguished itself, which stimulated lactic acid fermentation in the phytomass, which in turn had a positive effect on the preservation of dry matter, crude protein and metabolic energy, whose indicators were higher than the control by 5.47%, 1.64%, 1.47%.
