Abstract

Ammonia is an odorous substance, and it also forms secondary particle matter by causing chemical reactions with sulfur oxides and nitrogen oxides in the atmosphere. In this study, to evaluate the ammonia emission from weaned pigs, the ammonia concentration and ventilation rate were measured in mechanicaly-ventilated pig house. The measurement was conducted for about 45 days using INNOVA, a real-time measuring device based on photoacoustic spectroscopy. As a result, the average ammonia concentration in the pig house was about 3 ppm and the ventilation rate was 55 m³/h/pig. Finally, the ammonia emission from the weaned pigs in mechanically-ventilated pig house was about 1.6 g/day/pig. However, since ammonia emissions can vary by seasonal characteristics, it is considered that a long-term study of ammonia emission characteristics by season is needed to evaluate.
