  • Patent number: 6170434
    Abstract: A method of and apparatus for automatic milking of animals which comprises a number of steps such as cleaning the animal's teats, connecting teat receiving cups to the animal, foremilking, the milking operation as such, stripping, disconnecting the teat cups and disinfecting the teats. For each step, there are at least two variants. With the same animal, during a milking operation or in successive milking operations, different variants are applied, the variants being selected randomly by a random generator or to change periodically. The variants include the intensity and how the cleaning members are applied to the animal's teats, the sequence in which the teat cups are connected to the animal's teats, the locations of kinking places in the liner of the teat cup, the pulsation frequency, the release-suction phase ratio of pulsation, and the force with which the teat cups are decoupled from the animal's teats at the end of the milking operation.
