Definitions

  • the present invention relates to a method and a device for milking animals.
  • the invention will be described below in connection with a method and a device for milking cows. It should be noted, however, that the present invention may also be used in milking and milking systems for milking sheep, goats, camels, dromedaries, buffaloes, yaks, elks, horses, donkeys and other dairy animals.
  • the invention can be used in conventional milking, in automatic milking, in fully automatic and semi-automatic milking.
  • the use is also possible in systems in which semi-automatic or fully automatic or robot-assisted and / or computer-controlled preparation and / or cleaning of the teats and / or attachment of the teat cups to the teats of the animals takes place.
  • EP 1 000 535 A1 has disclosed a method for detecting the presence of specific substances in milk.
  • one or more properties of the milk which has been milked are checked with sensors provided in the milk line.
  • the milk, which has been milked from all teats, is taken to a common collection container. It is not possible to separate defective or unusable milk from individual teats or to separate milk of different quality levels. It the entire milk must be discarded if, for example, damaged or unusable milk from eg one teat has mixed with the milk of the other teats.
  • the present invention is therefore based on the object to provide a milking device that facilitates the separate collection of milk.
  • the device according to the invention for milking animals has a plurality or variety of teat cups, which are applied to the teats of the animal to be milked. Furthermore, a plurality or multiplicity of milk lines is provided for the further transport of the milk which has been milked. At a milking place at least two separate collecting containers are provided, in which milk from different teats of the animal flows and is collected there. According to the invention, at least one milk pump is provided downstream of the individual collecting containers, which serves for pumping out the milk from at least two collecting containers.
  • the milk milked by at least two different teats can be separated. This is sufficient for complete teat separation of the milk in animals, e.g. Goats completely out, as goats usually have exactly two teats. This allows the separation and separate collection of milk of different quality levels or unsuitable or unusable milk.
  • milk from diseased animals should not be put into the circulation for human consumption. This means that even if only one udder quarter of a cow has an illness, the milk of all quarters must be discarded and the entire milk must not be put into the cycle for human consumption. In compliance with this legal situation can be fed with the milk of diseased animals but eg calves.
  • the use of the invention now allows the milk of diseased quarters of the udder, e.g. completely discarded while the milk from healthy quarters e.g. can be used for feeding to calves.
  • the high-quality milk from healthy quarters can also be routed to the normal recycling loop. This considerably increases the flexibility in the milking process and the flexibility of handling milk from diseased quarters of the udder.
  • each teat of an animal to be milked is preferably assigned exactly one collecting container. For cows, these are four collection containers. In this way, the milk milked from each individual teat can be brought into a separate collecting container. In a further step it can then be decided whether and where the corresponding milk should be forwarded or whether the respective milk should be discarded if necessary. The decision may be made based on predetermined settings, e.g. according to specifications from the milking control or herd management program.
