Abstract: The invention provides a highly nutritional unfermented medium protein animal feed supplement by admixing wet corn bran having an abnormally high moisture content with concentrated corn steep to form a moist cohesive but friable mass, the process eliminating a significant proportion of the energy used in and pollution occasioned by prior art process. In a modification, the above unfermented product is subjected to a natural fermentation stage resulting in a fermented supplement which is microbiologically and gravitationally stable for an extended period of time. One further advantage of the present invention is that the corn bran and steep liquor from a corn wet milling plant can be used in the specific amounts as actually produced in the normal operation of the plant, thereby allowing plant efficiencies to be maintained.

Abstract: An animal feed supplement is produced from wet corn bran and corn steep liquor exiting a wet corn milling process. Wet corn bran is mechanically dewatered to 30 to 50% solids by weight and then thoroughly mixed with concentrated corn steep liquor having 40 to 55% solids by weight in a ratio of 3:1 to 1:1 to produce a mixture having 35 to 50% solids by weight. This mixture is compacted to form a moist, cohesive, friable, readily transportable mass having a bulk density of 50 to 65 lbs. per cubic foot, a pH of less than 4.5 and a protein content of at least 20% on a dry matter basis. The compacted mass may be permitted to undergo natural fermentation that is substantially anaerobic to a pH of less than 4.25 to produce an animal feed supplement that is microbiologically and gravitationally stable from two weeks to seven months.

Abstract: The invention provides a highly nutritional unfermented medium protein animal feed supplement by admixing wet corn bran having an abnormally high moisture content with concentrated corn steep to form a moist cohesive but friable mass, the process elminating a significant proportion of the energy used in and pollution occasioned by prior art process. In a modification, the above unfermented product is subjected to a natural fermentation stage resulting in a fermented supplement which is microbiologically and gravitationally stable for an extended period of time.

Abstract: A liquid animal feed supplement. The liquid feed supplement, which is gravitationally stable for prolonged periods of time, comprises essentially a colloidal mixture of spent brewers' yeast and a water dispersible water-binding agent in an aqueous alcoholic medium.
