Abstract
A milking apparatus comprises sets of electrodes for detecting milk flows sucked by individual teat cups capped on individual teats, tubes connected to pressure chambers of the respective teat cups, change-over valves operative to supply atmospheric pressure and vacuum periodically and alternately to the tubes, counters for counting times for non-detection of the milk flows by the sets of electrodes, and controller for actuating the change-over valves to supply only atmospheric pressure to the tubes when the counted times of the counters exceed a predetermined time.
