Abstract: The feed product for ruminant animals is palatable and nontoxic and comprises an energy producing starch bearing substance such as initially ungelatinized grains or vegetable starches; a protein producing substance derived from a nonprotein nitrogenous material such as urea or ammonium salts; and an inert liquid absorbing substance such as bentonite. The three substances are initmately mixed in predetermined quantities and then supplied directly, without any preconditioning treatment and at ambient temperature, into an extruder-cooker in which by frictional heat alone, a substantial portion of the starch in the energy producing substance is gelatinized and integrated with the nonprotein nitrogenous substance to produce the feed product. The resultant feed product has a substantially neutral pH and is characterized by a very slow ammonia release from the non-protein nitrogenous substance.
