Abstract

Odorous gas emissions from swine production are the unwanted by-product of farmers. Manure additive has a great potential to solve this problem. Manure additives are considered low-cost and user-friendly; they can be implemented without changing the current manure storage practices. The objective of this study was to evaluate the effectiveness of 12 current commercial manure additives on mitigating odor, ammonia (NH3), hydrogen sulfide (H2S), greenhouse gas (GHG), and volatile organic compounds (VOCs) from stored swine manure with pilot-scale setup by strictly following the recommended dosages and procedures from the product labels. Each product was tested for 2 months while gas and odor measurements were done weekly. At the end of the trials, manure properties and microbial communities were analyzed to determine whether manure additives impacting microbes in manure. Preliminary analyses indicate that there is no statistically significant reduction of any measured gas or odor emissions that could be associated with the tested products.
