Marcus Hollmann

Marcus's PhD effort focuses on management strategies to reduce methane (primary focus) and ammonia emissions from lactating dairy cows and manure management systems. The overall goal is to establish approaches to reduce net methane emissions from ruminant livestock operations using dairy cattle/farms as a model. In doing so, we hope to develop and implement practical strategies to mitigate greenhouse gas emissions to meet future national and state regulatory standards and to establish nutrition and management strategies to reduce, quantify, and certify reduction of emissions for carbon offsets in climate trading by animal agriculture.

Marcus’s specific research work will strive to define the mode-of-action and long-term efficacy by which a ration supplemented medium chained fatty acid (MCFA) can reduce enteric methane generation in ruminants; and, 2) to establish feeding regimens with MCFA and successive methods of manure treatment to reduce the net release of methane.  Much of his work will be conducted in our new (beginning September, 2007) MSU Air Quality Research Facilities where we have the ability to measure total gaseous exchange of twelve individual lactating cows simultaneously.  His work will be the foundation to support and complement the fundamental basis for an Integrated Project proposal to be submitted to the USDA/NRI Program 28 on Air Quality in the next 2 years entitled: “Reducing Emissions from Animal Farms to Achieve Regulatory Compliance and Provide Carbon Offset Credits”. 

The long-term aim of the Integrated Project is to use mitigation strategies to build and implement community-based partnerships to improve air quality and provide market-based opportunities for dairy/livestock farmers to capture revenue (e.g., carbon offset credits) from climate trading.  In the Integrated Project we shall propose to quantify and certify overall methane emissions reductions from the entire farmstead and compare those to pre-implementation emissions.  Results of research obtained through Marcus’s work will serve as the foundation of preliminary data to that end.
