A feeding stall for an animal that allows a gestating sow or other animal to enter the stall for feeding, in which movement of the sow triggers automatic closure of a gate assembly, without manual intervention from the farmer. This protects the sow from other sows when it is feeding. When the sow has finished feeding, it can readily exit the stall, opening the entrance gate without manual intervention. Opening and closing of the gate is actuated when the sow urges the gate assembly open or closed. The sow need provide only an initial impulse against the gate, with the remainder of the rotation being provided by a biasing member which urges the gate into the fully open or closed position after being tilted past a neutral position.
