  • Patent number: 4508058
    Abstract: The invention relates to a method of milking loose-housing cows which find their way individually to one or more feeding stalls where they are automatically identified and fed with the aid of a computer connected to the identification and feeding means.The new feature resides in that the computer is used for recording of the points of time each cow is milked and to activate a device, in connection with the identification of a cow arriving at the feeding stall to eat, and provided that a predetermined time has passed after the preceding milking operation, which device is activated for automatic application of the milking means to the cow's udder and for starting a milking operation.
