The trend in feeding growing-finishing swine seems to be toward feeding a complete mixed ration. However, many swine producers prefer to feed shelled corn and protein supplement free-choice. There are advantages and disadvantages to both methods and either method can be used for profitable production. Recent major emphasis on research has been on complete rations. More research is needed on additives in protein supplements which are formulated for free-choice feeding. The following experiment was designed to compare complete mixed rations and free-choice rations with combinations of L-lysine, methionine and yellow grease.
