Abstract: This stall comprises an endless articulated floor (6) which slides along a horizontal sole element (10) and passes around horizontal rollers (2, 4) mounted on a frame (1). Retainer plates (14) are laterally mounted on the floor and troughs (16) fixed to the plates extend across the space (18) between two adjacent plates so as to be accessible. Each plate (14) also carries a rocker element (20) which closes the access to the trough, is pivotable downwardly by the animal which desires to reach the trough, but rises so as to prevent the animal from leaving the trough before the end of the milking operation.
