METHOD AND DEVICE FOR DETERMINING GREENHOUSE GAS, IN PARTICULAR METHANE, EMITTED BY A RUMINANT, IN PARTICULAR A DAIRY ANIMAL

摘要

Method and device for determining greenhouse gas, in particular methane, emitted by a ruminant, in particular a dairy animal The invention provides a method and a device for determining the emission of greenhouse gas, in particular methane, by ruminants, in particular dairy animals. Eructations ("belches") of the animal are counted for this purpose. This is done by measuring a signal linked to the eructations, for example sound with a microphone. Given that the methane content of an eructation of this type is more or less constant, the total methane emission can be derived therefrom by counting.
