Description: This compact automatic feeder can be mounted above a metabolism crate to feed an experimental sheep 12 or 24 times per day. Twelve feed troughs (216 mm long, 152 mm deep, 76 mm wide) made from 5.5 mm thick galvanized mild steel sheet pivot on a 9.5 mm bright-steel bar mounted within the bottom of an angle iron frame. The opposite side of each trough is supported by a plastic catch attached to a solenoid mounted on the top center of the iron frame. When the solenoid operates, the weight of the trough and the feed that it holds causes it to pivot downwards and deliver the feed into the feed bunk of a metabolism cage via a feed chute. The solenoids are operated sequentially by a cam-timer. When the troughs are lifted by hand for refilling, the triggers are automatically reset. The total volume of the feed troughs is about 25 l, which allows up to 1.5 kg chopped hay to be fed daily in twelve feeds. Twenty four feeds/day could be obtained by modifying the timer and refilling twice daily.
