Abstract
A milking machine, which fastens teat cup liners R to teats B of a cow and repeats vacuum suction and quiescence for milking the cow, includes 1/f fluctuation signal generation module unit 2 for generating a 1/f fluctuation signal Ss based on the biorhythm of the cow and a control unit 3 for changing the control amount during milking, for instance, the number of pulses per unit time of a pulse control signal Sc for switching the suction and the quiescence, the duty ratio of the pulse control signal Sc, or the magnitude of the negative pressure corresponding to the 1/f fluctuation signal Ss.
