Methods for measuring and estimating methane emissions from ruminant

This open-access paper describes different (established and emerging) methods for measuring and estimating methane emissions from ruminants. The paper discusses the advantages and disadvantages of each method (Established: chambers/respiration chambers, SF₆ technique, in vitro gas production technique, and newer CO₂ methods. Emerging: micrometerological technique, combined feeder and CH₄ analyzer, and proxy methods) used to quantify enteric methane emissions. Model-based techniques were used to calculate national budget and single cow enteric emissions from intake and diet composition.

Part of a special, open-access issue on climate change and livestock management.
