Excerpts from the Introduction: Feeding tests with poultry have shown that beneficial results can be obtained by an ingredient change in mixed feeds. In place of soybean oil meal and an added "inedible" fat in the ration, cooked unextracted soybean meal can be used. This finding opens the door for consideration of direct conversion of soybeans to feed mixing uses by feed mills or other feed processors. Economic questions of feasibility of processing soybeans this new way need to be resolved. A feed mixer or other processor of cooked unextracted soybean meal needs the means of deciding which is cheaper, tallow or grease added to a feed mix with soybean meal, or soybeans plus the cost of processing them this new way. This study was made to obtain preliminary evaluations of the various factors influencing this economic decision. A satisfactory commercial process for producing cooked unextracted soybean meal has not been completely worked out. Equipment manufacturers need to design equipment with processing costs per unit within the potential margins allowable. Economic research is needed to bridge the gap between nutrition research findings on cooked unextracted soybean meal as a poultry feed ingredient and commercial adoption of the product. Possible users of such new equipment need a guide as to the potential for profit it offers.
