Abstract: An improved process for treating grain used for animal feeds includes steps of conditioning the grain to soften the grain coats, quickly heating the grain to a temperature just below a temperature sufficient to cause the grains to burst, compressing the heated grain between rollers to cause the grain to burst, further pressing the burst grains into flakes, and cooling the flaked grain. During the cooling step water is added to bring the moisture content of the final product to a desired level; digestibility enzymes and other additives are added with the water.
