Efficiency of biological preparations at the cancery of the green weight of lucerne

Laboratory studies were carried out to evaluate the effectiveness of the use of various biological preparations in the preparation of juicy feed from the green mass of alfalfa using biological preparations Bioamid-3 (Saratov), Ferbak-Sil (Kazan). Control served as an option without preservative. The results of the experiments showed the effectiveness of the use of the biological drug Ferbak-Sil. The maximum concentration of dry matter and exchange energy was established in the sample with this preservative, which was 2.27 MJ / kg and 27.2% and was above the control by 3.19 and 0.8%. The leader in the concentration of lactic acid in ready-made silage was established in the hay with Ferbak-Sil (2.31%), which was above the control by 0,54%.
