ABSTRACT OF THE DISCLOSURE The invention provides for a method and apparatus for milking an animal such as for example a cow. The method includes applying a teat cup to a teat of a cow, or similar animal, the teat cup having an infla- tion; the interior of the inflation being in communi- cation with a milk line connected to a source of vacuum. The exterior of the inflation is in communi- cation with a pulsating vacuum source and the method is characterised in that before milking commences the exterior of the inflation is subject of a lower vacuum (or higher pressure) than the interior of the inflation. The apparatus provides means for controlling a vacuum level applied exteriorly to an inflation of a teat cup. The apparatus includes a housing; an inlet port capable of being connected to a source of applied vacuum; and an outlet port capable of being connected to the exterior of a teat cup inflation. A valve is provided which is capable of moving in response to applied vacuum, to restrict or close off the inlet port and means are provided for gradually increasing the movement of the valve to increase the vacuum level.
