A machine for storing and automatically dispensing a pre-measured quantity of hay, grain, pellets and food supplements to single or multiple livestock type animals at predetermined times. Comprised of a enclosure containing a plurality of compartments each having the capacity of storing an amount of food for one feeding for either a single animal or multiple animals. A plurality of horizontally mounted doors, one per compartment, affixed to the enclosure frame on one side by means of a hinged joint. Opposite the hinged joint, a spring loaded latch bolt mechanism is affixed to the door. The hinged joint allows the door to fall by gravity into a vertical position allowing the feed to fall into a integral hayrack and trough located directly below the feed compartments. The horizontal doors are opened electrically, utilizing a electric door opener affixed to the support structure at each door position, aligned as to mate with a latchbolt attached to the horizontally mounted hinge door, which when energized allows the door strike to pivot free from its closed position. This allows the door to swing down dispensing its charge of feed. The timing and sequencing used to open the feed dispensing doors automaticly on a selected predetermined feeding schedule is accomplished utilizing a solid state Programmable Logic Controller. The animal owner selects a feeding schedule with a selector switch. A portable computer can be used in the event programing needs to be modified.
