Greenhouse Gas Odour Emissions from Pig Production Buildings, Manure Storage and Manure Treatment Facilities
Livestock operations and manure management contribute largely to the agricultural sectors greenhouse gas emissions. Nitrous oxide, carbon dioxide, methane and odour emissions were studied in Quebec and Saskatchewan swine operations. Carbon dioxide was the most prevalent of the greenhouse gases measured with the largest amount in grower-finisher rooms. Nitrous oxide production was negligible and methane amounts were fairly low. Covered earthen manure storage basins had much better results compared to uncovered, showing the importance of blown chopped straw covers on emission and odour control. Summer emissions tended to be much higher than the fall and winter. Carbon dioxide emitted from production buildings in the main contributor to greenhouse gases. The bio-filter treatment system had emitted more odours compared to the aerobic-anoxic manure treatment system.
