Abstract: Livestock production significantly contributes to emissions of polluting gases emissions like ammonia (NH3) and greenhouse gases. Pig production is globally responsible for about 15% of ammonia emissions. The aims of this paper were the comparison of the ammonia concentrations in the farrowing pens with permanent limited range of motion between the zones of lactating sows and piglets and the impact of the day hour on ammonia concentration in this place. Photoacoustic infrared measuring devices INNOVA were used. The average values of NH3 concentration ranged from 0.787738 ppm (0.547478 mg/m3) to 0.818091 ppm (0.568573 mg/m3). The minimum concentration of NH3 was measured in the second lactating sows zone (0.262535 ppm, 0.182462 mg/m3) and the maximum concentration was measured in the piglets zone (1.61803 ppm, 1.124531 mg/m3). Values measured met the requirements of the Decree No. 230/1998 of the Ministry of Agriculture and Rural Development of the Slovak Republic which allows the maximum concentration of NH3 in the pig building 20 ppm (13.9 mg/m3). There were no differences between the concentrations of the greenhouse gases (GHGes) in the zones of lactating sows and piglets.
