Abstract
A feeding system for delivering feed to troughs associated with rows of animal confinement cages is disclosed. The system comprises mobile hopper means for carrying a load of feed past troughs associated with each row of animal confinement cages. Delivery means extend from the hoppers; these delivery systems each receive feed from the hopper and deposit the feed in the feed troughs. The delivery sub-systems include a tube extending from a hopper and hopper conveyor toward a distal tube end at the trough. A shoe is attached to the tube at the distal end so as to support that tube distal end at the location spaced above the trough bottom. A grader blade is pivotally attached to the shoe in such a position as to be located behind the tube when the shoe and tube are moving in a forward direction along the trough.
