Description: An inexpensive, compact twelve compartment automatic feeder for cattle is shown above in image two. Twelve stainless steel feed boxes (13 cm wide, 25 cm long, 31 cm deep, volume .01 cu.m/box) are mounted on a 5 cm X 5 cm angle iron frame (105 cm X 75 cm X 30 cm deep), image one, which can be mounted above the feed bunk in a tie-stall or stanchion barn. The hinged overlapping base of each box has a 2-cm vertical lip on three sides to prevent feed spillage and is supported by a metal catch attached to a horizontally mounted, spring loaded, solenoid, image three. When energized, the retaining catch is released by the solenoid, allowing the base to fall, delivering the feed. The solenoids are operated sequentially by a timer via a 12-position single pole switch. The feeder must be refilled every twelve hours if hourly feeding is required. The volume of this machine for twenty four hourly feedings (.24 cubic meters/day) allows the feeding of up to 60 kg per day corn silage, 25 kg per day chopped forage, 150 kg per day pelleted feeds or concentrate, or a combination of feedstuffs sufficient to feed a high producing dairy cow during sophisticated experiments on metabolism. Long forages cannot be fed because of the narrow width of the boxes.
