Abstract: Described are stable, starch-rich liquid animal feed suspensions having a high dry matter content and which do not require added heat or suspension agents for starch gelatinization and stabilization of the suspensions. Enzymatic hydrolysis and mechanical grinding are used to release starch and produce a gel-like suspension from a starting grain product, such as seeds or kernels of corn, wheat, barley, millet, oats, or rice, or flours made from the grain seeds or kernels combined with a plant processing by-product such as dried distillers grain solubles, condensed beet molasses solubles, whey, and corn steep liquor. The products produced through the processes of the present invention are flowable, dark brown to golden, gel-like suspensions with a pH of 5-7 and viscosities of 500-1000 cP at ambient temperature. In addition, the products had comparable nutritional profiles to a commercial liquid feed supplement.
