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.

Abstract: The invention provides a device and method for milking a dairy animal, comprising at least two sensors for measuring milking parameters. Usually, an alarm is generated if a specific number of parameters each are outside a given range. According to the invention, now an alarm is also generated if said specific number of exceedings is not achieved, but if another, and usually greater, number of parameters each are within a larger, more flexible, range. As a result thereof, the actual alarm parameters with ‘hard’ limits can be selected, in order that false-positive messages are prevented to a considerable extent. In the grey area of almost exceeding, an alarm can still be generated if sufficient parameters are in dubious areas.
