Assessment of the sulfur hexafluoride (sf6 gas) tracer technique

Abstract. A commonly used method of measuring enteric methane (CH4) emissions from ruminants is the Sulfr hexafluoride tracer technique that measures respired and eructated CH4. However, within the animal, a small proportion of CH4 is produced post-ruminally and some of this may escape through the rectum. The comparison of emissions using a chamber technique that measures all enteric CH4 losses, and the gaz sf6 tracer technique, could give some insight into the magnitude of post-ruminal emission.
