Beef cattle, in particular, release methane (CH4) as a result of the digestion of feed materials in the rumen. These emissions are called enteric emissions and are a significant contributor to greenhouse gas emissions from agricultural activities. Other emission sources for cattle include methane and nitrous oxide (N2O) emissions are generated from manure storage and handling within beef cattle operations. A reduction in the number of days beef cattle are on finishing diets, or a decrease in the feed to gain ratio during the finishing stage results in a reduction of these emissions.
