ABSTRACT A milking machine comprises at least one teat cup containing a liner for receiving a teat, and means for subjecting the interior of each liner to a pressure, which is lower than atmospheric pressure, and for subjecting each pulsation chamber formed between each teat cup and its liner, to a pulsating pressure varying between a low pressure and a high pressure, which high pressure is higher than the pressure in the interior of each liner. Further, the machine comprises means for controlling the respective pressures in each liner and each pulsation chamber, and a means for indicating the volume of the milk flow. During milking, the milk flows from the teats in a flow, which first increases to a main flow level, then stays at said main flow level, and during a terminating phase of the milking, decreases from the main flow level. According to the invention, the pressure control means are adapted to control the various pressures in response to the indication means indicating during said terminating milking phase that the milk flow has decreased to a predetermined portion of the main flow, such that the low pressure in each pulsation chamber is higher than the pressure in each liner at least during a part of the terminating milking phase. The invention also relates to a method of milking by means of such a milking machine.
