The swine industry is a multi-million dollar business in the United States, concentrated primarily in the Corn Belt area. In South Dakota, which is located on the fringe of the Corn Belt, swine production is an important part of the economy of the state, which ranks ninth among all states, in hog numbers. Because of this tremendous volume of business, feed companies have put great emphasis on feed additives in an effort to lure farmers into buying their product. With the attention focused on antibiotics, chemobiotics, enzymes, natural and synthetic hormones, tranquilizers, and other feed additives designed to increase the efficiency of perk production, there is a tendency to forget about one of the prime essentials in a ration, an essential for life-protein. Lysine, a constituent of protein, is an essential amino acid, which is required in the ration of non-ruminants, including swine. The importance of lysine has been shown many times, however, since corn is the common grain fed to swine, most of the experiments pertaining to lysine were conducted with corn rations. This experiment was conducted to determine the value of supplemental lysine when added to oat rations as determined by rate of gain and feed efficiency.
