Enteric methane emissions are a byproduct of the digestion process of dairy cattle and can contribute up to 50% of a farm total greenhouse gas emissions. Careful examination of accounting methods is critical when examining enteric methane emissions, as the methods have a large impact on the results. This fact sheet highlights methods for measuring enteric methane emissions with in vivo and in vitro techniques plus methods for predicting emissions using mechanistic and empirical models (6 pages; 2017).
