Abstract
A method of feeding hogs is disclosed.

These feeding periods are alternated with three feedless periods during which all feed is denied to all the small hogs. This feeding regime is maintained until the hogs weigh approximately 100 pounds. Thereafter, two limited feeding periods are provided each day until the hogs reach market weight. In this way, hog weight gain per day is maximized and the amount of feed consumed per pound of hog weight gained is minimized. Apparatus for carrying out this feeding method is also disclosed. The apparatus includes a feed pan or trough, a high capacity feed delivery conveyor, and a timed feed shut-off means interposed between the feed trough means and the feed delivery conveyor for alternatively delivering and preventing delivery of feed to the feed trough. If desired, a …
