dc.description.abstract <p>Comprehensive control of odors, hydrogen sulfide (H<sub>2</sub>S), ammonia (NH<sub>3</sub>), and greenhouse gas (GHG) emissions associated with swine production is a critical need. A pilot-scale experiment was conducted to evaluate surface-applied soybean peroxidase (SBP) and calcium peroxide (CaO<sub>2</sub>) as a manure additive to mitigate emissions of odorous volatile organic compounds (VOC) including dimethyl disulfide/methanethiol (DMDS/MT), dimethyl trisulfide, <em>n</em>-butyric acid, valeric acid, isovaleric acid, <em>p</em>-cresol, indole, and skatole. The secondary impact on emissions of NH<sub>3</sub>, H<sub>2</sub>S, and GHG was also measured. The SBP was tested at four treatments (2.28–45.7 kg/m<sup>2</sup> manure) with CaO<sub>2</sub>(4.2% by weight of SBP) over 137 days. Significant reductions in VOC emissions were observed: DMDS/MT (36.2%–84.7%), <em>p</em>-cresol (53.1%–89.5%), and skatole (63.2%–92.5%). There was a corresponding significant reduction in NH<sub>3</sub> (14.6%–67.6%), and significant increases in the greenhouse gases CH<sub>4</sub> (32.7%–232%) and CO<sub>2</sub> (20.8%–124%). The remaining emissions (including N<sub>2</sub>O) were not statistically different. At a cost relative to 0.8% of a marketed hog it appears that SBP/CaO<sub>2</sub> treatment could be a promising option at the lowest (2.28 kg/m<sup>2</sup>) treatment rate for reducing odorous gas and NH<sub>3</sub> emissions at swine operations, and field-scale testing is warranted.</p>
