ABSTRACT:
A pig nursery feeder is provided which has an overall box-shaped configuration and is made substantially of steel plates welded to one another. The upper section of the feeder which constitutes the major feed storage volume thereof, includes tapered lower side walls which converge to form a decreasing cross-sectional area in the downward direction. Feed openings are provided at the bottom of the lower section of the feeder. At an intermediate section at the upper part of the lower section, the side walls of the feeder converge outwardly so as to present an increasing cross-section expanded throat portion for promoting free flow of the feed into the lower portion and to the feeder openings. To accommodate adjustment of the openings, the slide panels are connected to hand operable cranks disposed at the top of the feeder so that the feeder opening adjustments can be made independently of the amount of feed in the feeder and independently of any separate tools.
