Abstract:
A method and a device for determining the emission of greenhouse gas, in particular methane, by ruminants, in particular dairy animals includes counting eructations (“belches”) of the animal. 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.
