  • Patent number: 5979358
    Abstract: In a process for milking animals and with the aid of teatcup liners, each teatcup liner is brought to be cyclicly partly opened during an initial milking phase (I), when the teat in the teatcup liner still is slack, so that the teatcup liner is prevented from crawling upwards on the teat and throttle the milk passage between udder and teat. During a subsequent main phase (II) of the milking, when the teat is extended, the teatcup liner is brought to be cyclicly opened at least substantially completely. The initial phase is ended and the main phase is started when at least one monitored milking variable reaches a predetermined value. According to the invention the milking variable is the milk quantity extracted from the animal. Alternatively, further milking variables may be monitored such as the milk flow and the time from the beginning of the initial phase (I). Hereby the initial phase can be adapted to individual animals, whereby the milking time is minimized.

  • Patent number: 5769024
    Abstract: In a milking process the animal is stimulated during a stimulation phase (I) for initiating the animal to let down milk in the udder, while a relatively small milk flow is achieved. During a subsequent main milking phase (II) the animal is treated to eject a relatively large milk flow. The stimulation phase is ended and the main milking phase is started when at least one monitored milking variable reaches a predetermined value. According to the invention the milking variable relates to the milk quantity extracted from the animal. Further milking variables may be monitored such as milk flow and the time of the stimulation phase, so that the stimulation phase is ended when any of the monitored milking variables reaches a predetermined value. Hereby the duration of the stimulation phase can be adapted to the individual needs of the animals.
