Technical Abstract: Bedding materials may affect air quality in livestock facilities. The objective of this study was to compare headspace concentrations of odorous volatile organic compounds (VOC), total reduce sulfur (TRS), CO2, CH4, and N2O when corn stover, bean stover, wheat straw, switch grass, pine wood chips, pine wood shavings, ground corn cobs, and paper were used as bedding in lab-scaled bedded manure packs. Ground corn cobs and paper produced higher VOC, CO2, and CH4 concentrations than other bedding materials. Wood shavings also produced high concentrations of CO2 but had significantly lower VOC concentrations than other bedding materials. Corn stover had the highest TRS concentration. Nitrous oxide was similar across all bedding treatments. Results of this study indicate that ground corn cobs or paper may increase odor and greenhouse gas production when used in deep-bedded livestock facilities.
