Abstract: A space divider of a milking parlor arrangement for at least one milking parlor for milking milk-producing animals, wherein the space divider is arranged approximately parallel to a longitudinal axis of the animal to be milked, has an arm device having a milking cluster, which can be adjusted from a parking position to a working position and back. The arm device is arranged with the milking cluster in the parking position in the space divider and can be adjusted into the working position laterally to the animal to be milked between the front and rear legs thereof. The space divider may include a replaceable service unit.

Abstract: An optical milk measuring arrangement operative during a milking operation, and including an optical measuring device for measuring optical properties of milk in a measuring region, in which at least part of the milk fed to the measuring arrangement collects. The measuring arrangement includes a main channel and a measuring channel, and these channels are in fluid communication with one another in a region of a common inlet and a common outlet, and the measuring channel has a lower flow velocity than a flow velocity in the main channel.

Abstract: A space divider of a milking parlor arrangement for at least one milking parlor for milking milk-producing animals, wherein the space divider is arranged approximately parallel to a longitudinal axis of the animal to be milked, has an arm device having a milking cluster, which can be adjusted from a parking position to a working position and back. The arm device is arranged with the milking cluster in the parking position in the space divider and can be adjusted into the working position laterally to the animal to be milked between the front and rear legs thereof. The space divider is designed in such a way that no additional space is required between adjacent animals, so that many animals can be milked in a milking parlor arrangement while the smallest possible amount of space is required.
