Swine in Confinement - Feeding

It's no news that hog feeding has moved out of the slopping stage. With the movement from pasture to houses and the shift from a small number of slop-fed hogs to larger scale production, swine producers soon learned that when swine are confined without vegetation, more care had to be taken with rations. And, with feed costs accounting for two-thirds to nearly nine-tenths of the total production cost, no wonder so much attention has been paid to rations, feeds, and feeding.
