This article presents a field study of CH4 and CO2 emission from two 1100-head mechanically ventilated pig (Sus scrofa) finishing barns (B1 and B2) with shallow manure flushing systems and propane space heaters from August 2002 to July 2003 in northern Missouri. It was found that the CH4 and CO2 released from the flushing lagoon effluent were equivalent to 9.8 and 4.1% of the CDFB CH4 and CO2 emissions, respectively.
