Abstract: A method for testing of animals being milked, the system including a plurality of milk meters. A portable remote control device is provided to input data to the milk meters, receive and store data from the milk meters and display at least selected data. The remote control device is pre-loaded with animal related data and information relative to animals being milked is transmitted from the remote control device to the milk meters. Transmission of information from the milk meter as a consequence of an animal being milked is transmitted to the remote control device to enable updating of a record relevant to the animal being or having been milked. The remote control device thus provides a single interface with all milk meters for the inputting and receiving of data.
