This report presents detailed technical guidelines on using the SF6 tracer method for measuring enteric methane emissions. The report covers the pre-experimental planning requirements, permeation tubes, sampling systems, special considerations for ruminally-cannulated animals, sampling background air, sample analysis, animal measurement, methane emissions rates, data quality and data control, and SF6 reporting.
