Each of a series of milking stalls is bounded laterally by lateral barriers, rearwardly by a common butt plate, and at the front by a pair of pivoted gates which close rearwardly when a cow is loaded against the cow's shoulders. The gates for a particular stall are closed automatically as a cow enters the stall, brushing past a pivoted flap which triggers actuation of a pneumatic cylinder linked to the gates for that stall.
