Abstract: A milking machine detects a flow rate of milk during milking and integrates by a completion timer the time when the detected flow rate is smaller than a reference flow rate near an end of the milking, the integrated time being displayed graphically. The reference flow rate is corrected by a specific resistance of milk. The specific resistance is obtained by selecting a minimum resistance value from resistance values of milk which are actually measured during a predetermined time interval starting from a time after milking begins when a flow rate of milk measured on the basis of a predetermined standard resistance value reaches a predetermined value.

Abstract: A milk-claw for collecting milk sucked from cow's teats through teat cup liners and sending it to a vacuum milking machine, in which the horizontal sections of the collecting chamber in the milk-claw are formed polygonally to prevent the milk which flows into the milk collecting chamber through liner nipples from forming a whirlpool, and the vertical section of the collecting chamber is formed polygonally to prevent milk directed forcibly through a liner nipple into the milk collecting chamber from flowing backward through another liner nipple.
