Recent Research Efforts to Reduce Greenhouse Gas Emissions
This webinar will discuss research projects focused on reducing greenhouse gases, odorous volatile organic compounds (VOCs), ammonia, and hydrogen sulfide. Mindy Spiehs will provide insight on anabolic steroid and ionophore usage in beef cattle production, and Baitong Chen will discuss the use of manure additives and their impact on greenhouse gas emissions in swine manure storages.

Jun 21, 2019 1:30 PM in Central Time (US and Canada)

Mindy Spiehs
Research Animal Scientist @USDA Agricultural Research Service at the Meat Animal Research Center in Clay Center, Nebraska
She received her Ph.D. in Animal Science from the University of Minnesota, and served as a Regional Extension Educator – Livestock Manure Systems at the University of Minnesota from 2004 - 2007. Her current research is focused on air quality around livestock facilities. She has conducted studies to evaluate ammonia, volatile organic compounds, and greenhouses gases from cattle waste when wet distillers grains with solubles are fed to finishing cattle, and the effect of multiple feed additives on odor and gas concentrations on the feedlot surface. She has been involved in research to quantify air quality in beef deep-bedded monoslope facilities, with a particular interest in the effect of bedding materials on odor and gas concentration from these facilities. Current research evaluates management strategies in the feedlot and amendments for the feedlot surface that can reduce odors and greenhouse gas emissions.

Baitong Chen
Master student in Agricultural and Biosystems Engineering @Iowa State University
He received his bachelor's degree in Chemical Engineering at Iowa State University. His current research is to evaluate current manure additives for use in deep pit swine manure storage structures for mitigation of odors and reductions of ammonia, hydrogen sulfide, volatile organic compounds, and greenhouses gases emissions from stored swine manure.
