Alfalfa in the form of ground hay or alfalfa meal has been widely used in swine rations to improve litter size and survival of baby pigs. Some nutritionists suggest the possibility of valuable unidentified factors in alfalfa meal; however, the role of alfalfa meal in modern swine rations needs to be clarified to evaluate dehydrated alfalfa meal in rations for swine continually confined in pens with concrete floors, two experiments were started in 1958. Experiment 1 included four trials with growing pigs and Experiment 2 included four trials with breeding gilts.
