The modern technology applied on poultry enterprises of the Republic of Belarus made provision for high concentration of poultry population density at the comparatively small housing areas of integrated poultry farms which caused the deterioration of sanitary conditions in poultry houses, especially by the end of the growing period. Broiler chickens grown under such conditions were constantly experiencing the microbe stress which eventually caused the heightened culling and poultry losses caused by different diseases caused both by pathogenic and conditionally pathogenic microflora. For the current disinfection in presence of poultry it was proposed to use sprayings with malic and succinic acids, which made it possible to realize not only the air sanation in poultry houses, but also increase broiler chicken viability. The highest bactericidal activity of apple acid aerosol against air microflora was stated within 3 hours after carrying out indoors treatment. After disinfection the general microbic air contamination decreased in 2-10 times, quantity of microorganisms of colimorphic groups and staphilococcus in 1,4-1,75 and 2-10 times, respectively, in comparison with the original air values realized before air treatment in poultry houses. In the following, there was stated the gradual increase of a level of microbic air contamination within 24 hours. The best effect of the preparation was stated against Staphylococcus. Thus, the quantity of Staphylococcus in air decreased in 10 times in comparison with initial data
