Abstract. In 2016, in the scientific and technological center of animal husbandry of Tatar Research Agricultural Institute laboratory studies were carried out to assess the efficiency of the use of various biological preparations for conservation of succulent forage from green mass of purple alfalfa (Medicago sativa) ‘Aislu’, grown in the experimental field in Laishevsky district, the Republic of Tatarstan. The dried mass of alfalfa was conserved using biological preparations Bioamid-3 (Saratov), Ferbak-Sil (Kazan), BioAgro (Kazan), Biotrof (Saint-Petersburg), Sila-Prime (the Republic of Belarus) and Fidtekh F18 (the Czech Republic). The variant with Biotrof preservative was served as a control. The content of exchange energy in 1 kg of dry matter of raw material was 4.21 MJ/kg, of crude protein – 12.35%, of crude fiber – 6.91%, of nitrogen-free extractives – 33.30%, of sugar – 16.39%. The maximum concentration of exchange energy was established in the sample with BioAgro preparation, which was 3.74 MJ/kg, and it was above the control by 6.55%. The minimum concentration of exchange energy was established in plant raw materials with Ferbak-Sil preparation (3.63 MJ/kg), which was above the control by 3.42%. The content of raw protein and crude fiber in the finished feed, prepared with Bioamid-3, was greater than in the control by 3.90% and 2.77%, respectively. The leader in the concentration of lactic acid in prepared haylage was feed with Fidtekh F18 (93.62%), which was above the control by 0.8%. The minimum cost of 1 MJ of exchange energy and crude protein was in haylage, preserved with BiоАgro, Bioamid-3 and Ferbak-Sil biological preparations, it was lower the control by 6.0%, 4.67% and 3.67%. With the use of preservatives of foreign production: Fidtekh F18 and Sila-Prime, the cost of 1 MJ of exchange energy and crude protein of ready silage increased by 11.0 and 1.67%, 16.19 and 5.72 % in comparison with the control.
