    • 1505930 Ruminant feeds KANSAS STATE UNIVERSITY RESEARCH FOUNDATION 15 Sept 1975 [24 Feb 1975] 37767/75 Heading A2B A ruminant feed is made by admixing an ungelatinised starch bearing material selected from corn, sorghum, millet cassava, potatoes, jams, rice, corn starch, potato starch, wheat starch, arrow root, turnip, and rutabagus with an N.P.N. substance 0.25-10% of a lipid, based on the weight of starchy material, and a quantity of water; subjecting the mixture to heat, pressure and shear to cause at least partial gelatinisation of the starch and reaction of the NPN substance therewith; and releasing the pressure to give an expanded product. The N.P.N. substance may be urea, uric acid, biuret, ethylene urea, ammonium phosphate, bicarbonate, carbamate, citrate, formate, acetate, propionate, lactate, succinate, fumarate or maleate, diammonium phosphate, propionamide, butyramide, formamide, acetamide, dicyanodiamide, isobutane diurea, creatinine or creatine. The lipid may be an animal fat or grease, a vegetable oil or fat, or soybean lecithin. The heat treatment may be at 220-360‹F and 300- 500 psi followed by extrusion, which causes expansion. The protein equivalent may be 24- 125, the degree of gelatinisation 50-100%, and the final moisture content less than 15%. The mixed ingredients may be pre-treated with steam or water before heat treatment.
