Description

Agricultural activities, including the production of livestock, result in greenhouse gas emissions to the atmosphere. 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. This protocol for reducing the number of days on feed for beef cattle addresses both digestion and manure storage and handling emission sources for livestock greenhouse gas emissions. It allows users to quantify greenhouse gas reductions using scientifically valid equations and emission factors resulting from a reduction in the number of days required to complete the finishing stage of beef cattle in a feedlot resulting in a decrease in both enteric and manure...
