Ammonia and Greenhouse Gas Emissions of a Swine Breeding-Gestation-Farrowing Facility in the Midwestern USA
نویسندگان
چکیده
Aerial emissions from livestock production continue to be an area of concern for both the potential health and environmental impacts. However, information on gaseous, especially greenhouse gas (GHG) emissions for swine breeding/gestation and farrowing production facilities is meager. A 4300-sow breeding, gestation, and farrowing facility in Iowa was selected for extensive field monitoring. A Mobile Air Emission Monitoring Unit (MAEMU) was installed to monitor the deep-pit breeding-early gestation barn (1800 head), the deep-pit late gestation barn (1800 head), and two shallow-pit (pull-plug) farrowing rooms (40 head per room). This paper reports on data collected from January 12, 2011 to March 31, 2012.

This study supplemented the National Air Emissions Monitoring Study (NAEMS) by making comprehensive measurements, over a full calendar year, of odor emissions from five swine and four dairy rooms/buildings (subset of the total number of buildings monitored for the NAEMS project). The measurements made in this project included both standard human sensory measurements using dynamic forced-choice ...

There has been an increased interest in alternative housing for laying hens in certain parts of the world, including the United States. Associated with the movement are many questions to be addressed concerning sustainability of such systems. This study continually quantifies concentrations and emissions of ammonia (NH3), carbon dioxide (CO2), methane (CH4), and particulate matters (PM10 and PM...
متن کاملAmmonia, Hydrogen Sulfide, and Greenhouse Gas Emissions from Wean-to-Finish Swine Barns Fed Diets with or without DDGS
In recent years the corn grain ethanol industry has expanded and led to increased availability of dried distillers grains with solubles (DDGS). As a result, feeding DDGS to swine is becoming more common in pork production. With feed being the primary cost in pork production and increasing interest in air emissions from animal feeding operations, it is important to understand the impacts of non-...

and Implications This on-going study is continuously monitoring emissions of gases including ammonia, hydrogen sulfide, carbon dioxide, methane and (intermittently) selected odorous volatile organic compounds (VOCs) as well as particulate matter (PM) from a 2500-head sow farm consisting of two gestation barns and one farrowing barn in central Iowa. An on-farm instrumentation shelter houses the ...

In this study, the comparison and monitoring of the initial greenhouse gas (GHG) emissions using a flux chamber and gas analyzer from three different liquid manure application methods at a swine farm in Kentucky were carried out. Swine slurry was applied to farmland by row injection, surface spray, and Aerway injection. Ammonia and GHG concentrations were monitored immediately after application...
