Indirect Measurement of Building Ventilation Rate for Manurebelt Laying Hen House Using CO2 Balance
Extension Number
ASL R2013
Topic
Poultry
Summary and Implications
Direct measurement of building ventilation rate in livestock housing is a formidable task due to uncontrollable variations in fan and system performance. Estimating building ventilation rate based on a CO2 -balance offers a potentially viable alternative to direct measurement. Building ventilation rates obtained by direct measurement and by a CO2 balance were compared in this study for a commercial laying hen house with manure belts. The results indicate that ventilation rates estimated by the CO2 balance method were not significantly different (P>0.2) from those as determined by the direct measurement when the averaging or integration time interval was two hours or longer.= Careful application of the CO2 balance method will greatly improve the affordability and versatility of endeavors toward quantifying air emissions from confined animal housing.
