Abstract
There is disclosed a solid animal feed supplement which is prepared in concentrated food industry by-products such as by-products of the dairy industry, such as whey permeates, delactosed whey, and by-products of the fermentation industry, such as whey and corn sweet water. The invention comprises the treatment of the protein-rich by-products with a mild enzymatic treatment which stabilizes the by-products against protein gelation, and the thermal, and/or enzymatic treatment of the lactose-rich by-products to avoid separation of the lactose from concentrates. The by-products can then be concentrated to high solids content, in excess of 50 weight percent, and the resultant concentrates can be treated with gelation agents, preferably phosphoric acid and lime to solidify the by-product. Feed nutrients such as fats, urea, sodium bicarbonate, calcium carbonate, calcium sulfate, etc., or drugs such as monisan, can be added before solidification forming useful solid animal feed supplements.
