Southeastern Broiler Air Emissions Study(Burns, Xin, Gates & Hoff)
• Air emissions from two Tyson Foods broiler houses in Western Kentucky are being monitored
• Both broiler houses monitored continuously for a one year period
• Monitoring for all emissions began in January 2006, emissions calculation period 2/20/06 – 3/1/07
Study Purpose
Data from this project are proposed as representative air emissions from southeastern U.S. broiler houses for use in the Air Compliance Agreement (ACA)
Pollutants Measured• Ammonia• Carbon Dioxide• Hydrogen Sulfide• Non-Methane Hydrocarbons• Methane• Particulate Matter
– Total Suspended Particulate– PM 10
– PM 2.5

Southeastern Broiler Air Emissions Project Schedule
ISU Layer NH3 Mitigation Study(Xin & Burns)
• NH3 emissions from two Rose Acre Farms High-Rise Layer houses in central Iowa are being monitored
ISU Layer NH3 Mitigation Study
• Both High-rise units house ~ 286,000 layers. Layers in the control house are fed a standard diet while layers in the treatment house are fed a diet designed to reduce ammonia emissions
MAEMU placement so that two barns (control & treatment) can be
measured using one unit
Layer NH3 Mitigation Study• NH3 emissions monitoring
system installation was recently completed
• NH3 emissions as well as bird performance will be monitored for one year from the control and treatment high-rise houses
Layer NH3 Emissions Study(Xin, Burns & Arthur)
• NH3 emissions are being calculated using a Nitrogen mass-balance approach for eight varieties of layers in conjunction with Hy-Line
• Project data collection is 2/3 complete
Recently Completed ISU Layer NH3Mitigation Studies
• Reduction of Ammonia Emission from Stored Poultry Layer Manure Using Additives: Zeolite, Al+clear, Ferix-3 and PLT. 2006 Li, Hong Li, H. Xin , R. T. Burns, and Y. Liang. Published in the proceedings of the 2006 ASABE Annual Meeting, Portland, Oregon.
• Effects of Stack Surface to Volume Ratio and Air Exchange Rate on Ammonia Emission of Laying Hen Manure Storage. 2005. Li, Hong and Y. Liang. Published in the proceedings of the 2005 AWMA Annual Meeting, Minneapolis, Minnesota.
