Validation of the sulphur hexafluoride (SF6) tracer gas technique for measurement of the methane and carbon dioxide production by cattle

Methane (CH4) and carbon dioxide (CO2) production from six crossbred yearling beef heifers (400 +/- 13.0 kg) were measured, using the sulphur hexafluoride (SF6) tracer gas technique (Tracer) and open-circuit hood calorimetry (Cal) to validate the former in estimating rumen CH4 and CO2 production in...
