The present invention relates to a method for milking animals wherein a negative pressure is periodically built up and relieved in a teat cup gap at a predetermined rate. The negative pressure is maintained over a predetermined suction phase (b) and relieved over a predetermined rest phase (d). The ratio between the suction phase (b) and the rest phase (d) changes at least once during the milking operation. In a preferred embodiment the first duration does not exceed a predetermined, first limit value and the second duration does not fall beneath a predetermined, second limit value.
