Ammonia gas is one of the malodorous gases from swine production facilities, such as manure
storage tank, manure fermentation facilities, and livestock houses, etc. Ammonia gas from swine
house is being emitted at relatively low concentrations throughout the year. Therefore, livestock
facilities were continuously ventilated to supply fresh air for respiration of the animals internal the
livestock facilities. The swine facilities need very high ventilation rate to control the inside
environmental conditions. The deodorization system of the livestock facilities must be developed
considering the ventilation rates. The odor abatement system was installed in order to improve the
internal environment of the naturally ventilated growing-finishing pig house. The system which
distributes the deodorized air into inner space of the swine house by using plastic duct was
installed. Since the internal environment, effected by the operation of the odor abatement system,
is monitored by closing the winch curtain installed on the side wall of the pig house, the
experiment was practiced at the season when the internal environment becomes aggravated, winter.
The effects on the improvement in the internal environment of swine house by operating the odor
abatement system are as follows ;
1. By re-distributing the air which was deodorized by the odor abatement system installed in
the pig house, the result showed that the concentration of ammonia gas is decreased approximately
33.3% compared with that before operating odor abatement system.
2. The effect on the pig house’s ammonia gas reduction was found that the ventilation rate was
less than 0.5 m³/minㆍhead.
The effect of the operation of the odor abatement system showed to be scarce when the
ventilation rate increases because of the influx of external fresh air makes the quantity of diluted
air more than those of the odor abatement system.
3. The perishment rate of the pigs which were breeded until slaughtering decreased about 3.8%
by operating the odor abatement system in the growing-finishing pig house. Also, after operating
the odor abatement system, the stinging of the eyes, suspension dust, etc were decreased when
going into swine house for management
