A rotary milking platform with a means of entrance and egress of animals in which each milking bail (4) is defined by two restraining rails (5). The angle of the bails (.alpha.) and the direction of rotation of the platform (arrow A) are both either clockwise or counter-clockwise so that a milked animal leaving via the exit means (7) can be seen by the next animal on the platform (2) to finish milking. The exit path (7) incorporates a curved restraining rail (8) against which an animal leaving the platform (2) is backed such that only the animal's front feet remain on the platform (2). The movement of the platform (2) turns the animal (Arrow E) and the shape and placement of the curved restraining rail (8) guides the animal to the exit means (7). The entrance pathway (6) is radially aligned so that an animal entering the platform (arrow B) is oriented to step onto the annulus (3) into a bail (4).
A rotary animal platform having an entry means and an exit means, in which said platform comprises a horizontally disposed annular platform mounted for rotational movement about a vertical central axis, the upper side of said platform being evenly divided into a plurality of bails each being sized to receive therein an animal and being open at at least the outer end, each said bail having a restraining rail along each side thereof and each bail being offset on an angle to a radial line through the bail wherein said exit means incorporates a curved restraining rail positioned adjacent the platform against which an animal leaving the platform is backed such that the animal's front feet only are on the platform, wherein the direction of movement of the platform is such that the movement of the platform turns the animal away from the centre of the platform and one of the bail restraining rails, with the curved restraining rail assisting in guiding the animal to the exit means.
