The mathematical model to analyze ammonia concentrations inside lifestock facilities has been made. The regression relationship of the intensity of the ammonia evaporation in the pigsty for the farrowing sows and their piglets has been determined. When the surface of the concrete floor of the stall is uneven and there is a manure layer of 0.5-1.0 cm thickness, the ammonia concentration in the pigsties of sows with piglets exceeds the upper permissible limit (20 ppm). When the relative humidity of the air is normal and the ammonia concentration exceeds the permissible limit, it should be reduced by technical and zoohygienic means ( by carefully cleaning the floor surface). This lowers the ammonia concentration from 25 ppm to 10-15 ppm, and its emission.
