<；P>；PROBLEM TO BE SOLVED: To provide a method for producing a feed raw material, by which vegetable oil alkali residues by-produced in processes for purifying vegetable oils and having almost been subjected to combustion treatments or the like as industrial wastes can more effectively be used in low production costs, and to provide an easily handleable feed raw material. <；P>；SOLUTION: This method for producing the feed raw material (mixed oil alkali residues 5) having a proper viscosity comprises a neutralization process for neutralizing rapeseed oil alkali residues 1 by-produced in a process for purifying a rapeseed oil as a raw material with an acid to obtain a rapeseed oil neutralized residues 2, a drying process for drying the rapeseed oil neutralized residues 2, and a mixing process for mixing an un-dried rapeseed oil neutralized residues 3 with the dried rapeseed oil neutralized residues 4. <；P>；COPYRIGHT: (C)2008,JPO&INPIT
