This chapter looks at the key techniques used for measurement of CH4 and other gas emissions from livestock production, ranging from individual animal measurements to herd scale measurements for grazing animals and whole farm emissions such as feedlots. Individual animal measurement techniques discussed include whole-animal respiration chambers and head capture measurement. Herd scale measurements include micrometeorological methods and the eddy covariance (EC) technique.
