Summary. The search of new disinfectants with a wide spectrum of antimicrobial activity of low toxicity and not hazardous in use, not requiring of creation of special storage conditions, convenient in use and not adversely affecting on processed items, affordable, is an urgent task of veterinary science. The article presents the results of laboratory tests of new bactericidal compositions, which include: 20% hydrated lime, 1.3 and 5% sodium chloride, as well as foaming agent PO-6K on test surfaces made of stainless steel, galvanized gland, tile, wood and concrete. As a test of microorganisms, museum cultures of E. coli (strain 1257) and Staphylococcus aureus (strain 209-P) were used. During the experiments, disinfection regimes were established (concentration, exposure, consumption of disinfectant) for disinfecting of smooth and rough test surfaces. At the same time, it was found that slaked lime solutions of 10 and 15% concentration did not have disinfecting activity even after triple whitening or irrigation of test surfaces contaminated with E. ooli (strain 1257), St. aureus (strain 209-P) at a rate of 0,5 l/m2 for smooth and 1 l/m2 - for rough surfaces. 20% solution of slaked lime, which destroys only Escherichia coli on smooth surfaces in 3 hours of exposure at the rate of 0,5 l/m2, and rough surfaces in 24 hours of exposure at the rate of 1,0 l/m2, has a disinfecting effect. At the same time, adding 1,3 and 5% sodium chloride to the slaked lime solution, the disinfecting activity of slaked lime also increases sharply; adding to 20% slaked lime 3 and 5% sodium chloride disinfects Escherichia coli and staphylococcus in 3 hours, based on smooth 0,5 l/m2, and for rough surfaces - 1 l/m2. Studies have also found that the addition of 3-5% sodium chloride, 5% foaming agent to 20% slaked lime solution reduces the consumption of the disinfectant in 2 times without reflecting the indicators of disinfection efficiency. When a foaming agent is added to the solution, the resistance (adhesion) of the foam on the vertical and ceiling surfaces increases on 14-18 minutes, and on the floor the foam is held in 1-1,5 hours, which helps to reduce the runoff of the solution.
