ЭФФЕКТИВНОСТЬ БИОЛОГИЧЕСКИХ КОНСЕРВАНТОВ ПРИ РАЗЛИЧНОМ СОДЕРЖАНИИ СУХОГО ВЕЩЕСТВА ЗЕЛЕНОЙ МАССЫ ЛЮЦЕРНЫ

Abstract

For the production of high quality silage, and reduction of losses of biological yield, the use of effective biological preparations is topical. In order to reveal the effectiveness of the preservation of nutrients from plant raw materials, a number of laboratory studies were carried out in 2016-2017 in the Tatar Scientific Research Institute of Agriculture (TatNIISKh). The object of research was haylage harvested from the green mass of alfalfa, grown on the experimental field “TatNIISh” in Laishevsky district of the Republic of Tatarstan. The nutritional value of the conserved green mass of the alfalfa (Medicago sativa) variety Aisleau in the phase of budding with different moisture was analyzed. Preservation of the planted plant mass was carried out using biological preparations Biotrof (St. Petersburg), Ferbak-Sil (Kazan), Bioamid-3 (Saratov). The variant with biological preparation Biotroph served as the control. The maximum content of exchange energy (EE), with an increased concentration of phytomass moisture, was established in the control sample, which was 2.36 MJ/kg and was higher than the experimental samples with Bioamid-3 and Ferbak-Sil preparations at 6.78 and 3.82 %. With an increased dry matter content in the green mass of alfalfa, this indicator was the maximum in the sample with the preparation Bioamid-3 (3.67 MJ/kg), which was higher than the control by 4.56%. The leader in the concentration of crude protein and crude fiber, with a high moisture content of raw materials, was set in a control sample and amounted to 6.11 and 6.07%, which were higher than the prototypes with Bioamid-3 and Ferbak-Sil preservatives by 0.33 and 0.16%, 0.76 and 0.48% respectively. The leading preservative for the preservation of raw protein and crude fiber, with reduced moisture content of raw materials, showed the drug Bioamid-3, whose indices were above the control by 0.39 and 0.23%.
