Air quality has moved to the forefront of environmental issues facing Wisconsin livestock producers. State agencies are exploring how livestock facility emissions and odors are impacting air quality. Producers will soon be faced with regulatory pressure to manage livestock facilities and feedlots to comply with air quality standards. The Wisconsin livestock industry has limited quantitative data to document actual on-farm emissions associated with housing facilities and feedlots. As regulatory agencies begin assembling air quality standards, the livestock industry has requested a baseline be identified for ammonia, hydrogen sulfide and odor currently generated from a variety of real farm facilities. Minimizing livestock facility impact on air quality will benefit public health, the environment and improve public perception of livestock agriculture.
