Ventilation rate (VR) is one of the two key elements for quantifying aerial emissions from animal production facilities. Direct, continuous measurement of building VR can be challenging and impractical under certain circumstances,e.g., naturally ventilated animal housing or a large number of ventilation fans in the building. This study examined the suitability of estimating VR of broiler houses with built‐up litter (mixture of manure and bedding), when supplemental heating was not in use, through either carbon dioxide (CO2) balance or the relationship of VR to CO2 concentration difference between exhaust and inlet air. The reference VR was based …
