Methods of Feeding Soybeans and Their Supplementation in a Hogging-Off Program

Abstract

Pigs “hogging off” soybeans (Tokyo variety) made more rapid gains in weight than pigs hand-fed soybeans in dry lot. Both groups, “hogging off” and dry-lot fed, which received both protein supplement and mineral mixture (which supplied calcium, phosphorus and common salt), made a greater average daily gain than the groups similarly fed without the additional protein supplement. The dry-lot group (E) fed a protein supplement made significantly greater gain than group G fed mineral mixture alone. Of the groups fed individually, the one receiving 20 percent corn and 58.5 percent soybeans in a supplemented ration made a greater average daily gain in weight to 85 pounds than the group fed 78.5 percent soybeans without corn in the diet. Upon reaching the weight of 85 pounds, all pigs were fed the hardening diet of com, fish meal and cottonseed meal to a marketable weight of 225 pounds with resulting good daily gains in weight.
