The health of productive animals is directly dependent on their housing conditions and utilization. The environment of livestock biocenoses must comply with current standards and be safe from a sanitary standpoint. Achieving this is only possible with the implementation of highly efficient disinfection technologies in production. A pressing issue today remains the development of innovative devices and methods for air decontamination in livestock facilities. Device construction was based on the results of patent research and a comparative analysis of existing analogs and prototypes. The effectiveness of disinfectants was assessed in accordance with applicable regulatory documents. As a result of the work carried out, a device was developed for air purification in livestock facilities. It features two-stage biological-droplet filters, sedimentation chambers, water supply regulation valves, water recirculation pipeline systems, and systems for water supply and drainage. A device for air sanitation in livestock facilities was also developed, which provides simultaneous air ionization and ultraviolet irradiation. This device includes a source of ultraviolet radiation and a water drainage and purification system for processed water. Additionally, methods for deodorization, aerosol disinfection, and fumigation of the air environment in livestock facilities were created. These methods involve the use of innovative disinfectants from various chemical groups under appropriate application regimes. They meet modern requirements for livestock management and are effective, environmentally safe, economical, and easy to use. The prospect of further research lies in improving technological approaches to decontaminating livestock environments.
