A feed of high energy content and rich in proteins, fatty acids and carbohydrates is prepared for livestock use by treating waste materials consisting essentially of cellulose, hemiceliulose and lignin, with a complex solution which induces a natural selection of the microbic flora normally present in the straw, and thus triggers guided and controlled fermentation processes. The production of the new livestock feed has required the provision of a new apparatus in which the section used for mixing the cellulose materials with the fermentation solution in constant predetermined proportions is original.
