A vertically movable feed trough moves between a lower feeding position and an upper loading position in which the bottom of the trough engages the flanges of the dispensing channel. A conveyor supplies feed to the tubular conduit and through the delivery openings to the space defined by the raised feed trough and the abutting flanges.
