The issue of protecting the environment from harmful emissions is currently urgent for virtually all poultry farms. At the same time, the increased concentrations of ammonia, carbon dioxide and hydrogen sulfide in the air of the poultry houses have a negative impact on the physiological state of the bird’s organism and farm personnel. The purpose of the research was to determine the effectiveness of the use of advanced techniques to reduce the microbial contamination of the air in the poultry houses and the content of toxic gases in the real production conditions and the economic effect of their use. We registered that ammonia content in the air of poultry houses of the new variant decreased by 2.6 times on the first day and by 1.9 times on the fifth day compared to the basic variant during the cold season; during the transition season it decreased by 2.3 times and 1.7 times, respectively. The total weight of the litter after removal from the premises in the experimental poultry house was by 95 t less than in the basic version, which allowed reducing transport costs. In the new version, 104,050 eggs or 18.834 t of egg mass more were received. The use of the proposed technological solutions contributed to some reduction in the specific feed cost: by 329 g - per 1 average laying hen, 11 g per 10 eggs, 51 g or 2.3% - per 1 kg of egg mass. The application of the proposed technological solutions provides an annual economic effect of 769.2 UAH per 1,000 heads and a payback period of additional costs is 0.7 years.
