개요
The study was carried out to develop the real time measuring technique of ammonia and carbon dioxide 채concentration emitted from growing-finishing pig house in winter and estimate ammonia emission rate emitted from the pig house. As the study was carried out, environmental management technique for the pig house and odor abatement skill could be properly developed to reduce the residence’s annoyance. The room temperature of the growing-finishing pig house was 10 oC higher than outdoor air temperature in spite of additional heating, because of heat emitted from body temperature of the pigs. The daily variation pattern of room temperature in the pig house shows the similar tendency with outdoor air temperature. The daily mean ventilation rate per head was 16 m3fh and ranged from 12 m3/h to 22.4 m3/h. The difference of day and night for ventilation rate was about 2 times. The ammonia emission rate was 208土28 mglh . pig per daily basics calculated with ventilation rate and ammonia concentration.
