• each milking position is arranged with direct access from the holding area.
• direct access means that an animal leaving the holding area will be able to enter an unoccupied milking position without deviation or interruption. That is, the animal leaving the holding area will either immediately set foot in the unoccupied milking position or an unobstructed passageway will lead the animal to the unoccupied milking position. Such an unobstructed passageway only leads to one milking position of the number of milking positions.
• An urging member may be provided in the holding area, see further below.
• the collecting area is an area in which the group of animals is held, or into which the group of animals is driven, prior to passing into the holding area. Accordingly, the collecting area is an area arranged for guiding and/or assembling and/or accommodating a group of animals to be passed into the holding area.
• the collecting area is arranged adjacent to the holding area i.e., no area is arranged between the collecting area and the holding area.
• the movable barrier forms a barrier that cannot be passed by animals. It is arranged at a therefore suitable height in the collecting area.
