Oil Sprinkling
Application: used within buildings
Pros
- Works within the building to clean air.
- Workers and animals may benefit from cleaner air.
- Relatively easy to apply by hand.
Cons
- Safety concerns due to slippery floor surfaces.
- Requires daily labor if applied by hand pump.
- Requires additional time during room washing to remove oil residue.

Pit Ventilation
Application: used within deep-pit buildings
Pros
- Very little cost if included in original design prior to construction.
- Construction using wall fans in lieu of pit fans may be simpler.
- Fans are more easily cleaned and maintained.
Cons
- More wall surfaces are used for fan installation.
- Potential for more particulate matter to be released during winter.

The purpose of the Air Management Practices Assessment Tool (AMPAT) is to provide an objective overview of mitigation practices best suited to address odor, emissions and dust at your livestock operation so that livestock and poultry producers may compare and narrow their options of mitigation techniques. Practices are divided into three categories by source: 1) Animal Housing; 2) Manure Storage & Handling; and 3) Land Application. Each mitigation practice has an individual page which includes a printable fact sheet and a short online slide presentation.
Urine / Feces Segregation
Application: used within buildings to reduce emission of odors and gases from the building and manure storage
Pros
- Improved air quality within the building for animals.
- Potential to increase nitrogen retention in liquid.
- Separation of nitrogen and phosphorus may have benefits.
Cons
- Difficult to incorporate into an existing building.
- Two waste streams must be handled.
- Equipment sources are not well developed.
- Maintenance could be a challenge.

UV Light
Application: used to reduce emissions from buildings
Pros
- Very effective for VOCs and odor reduction.
- Potential to remove pathogens.
Cons
- Technology is still not common and may require more development.
- Cost estimates are somewhat unknown.
- Filters may be needed to reduce the impact of particulate matter on treatment surfaces.
Description
Definitions
Ammonia: Ammonia is a colorless, pungent, nitrogenous gas. It volatilizes from a solid or liquid material when the ammonium ion is present and other physical conditions exist. Ammonia gas can react in the atmosphere with gaseous acidic species to form fine particulates (ammonium [NH4+] aerosols), which are a health concern. Atmospheric NH3 can be deposited during rain events and lead to soil acidification and increased concentrations of nitrogen in surface waters, potentially contributing to eutrophication.
Animal Housing
Diet Manipulation
Application: used for building ventilation air and manure storage emission
Pros
- Easily implemented when done in consultation with a nutritionist.
- Many options impact multiple emissions.
- Changes may cost very little.
Cons
- Additive and feedstuff availability and costs may fluctuate.
- Nutritional needs change as the pig grows and may lead to more complex feed choices.

Scrubber
Application: used to reduce emissions from buildings
Pros
- Very effective on multiple gases, odors and particulate matter.
- Stages can be designed to address specific pollutants.
Cons
- Expensive to implement and maintain.
- Creates another effluent stream requiring disposal.
- Requires a higher level of water usage that may be a challenge in some locales.
- May require special consideration to not negatively impact ventilation rates.
