Download Guidelines for estimating methane emissions from individual ruminants using: GreenFeed, ‘sniffers’, hand-held laser detector and portable accumulation chambers

The methods used to determine CH4 emissions from individual animals differ in complexity, labour requirements, cost, throughput, animal management, duration of measurement, accuracy, precision and repeatability over time. Respiration chambers and the sulfur hexafluoride (SF6) tracer techniques have been accepted as the main measurement techniques to determine CH4 emissions from individual animals over several decades. However,..
