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.

We claim: 1. A process for making an animal feed product, comprising the steps of: (a) providing a grain; (b) adding a plant processing by-product and optionally water; (c) adding an enzyme to create a mixture; (d) incubating the mixture under conditions wherein the enzyme reacts with the grain
We claim: 1. A process for making an animal feed product, comprising the steps of: (a) providing a grain; (b) adding a plant processing by-product and optionally water; (c) adding an enzyme to create a mixture; (d) incubating the mixture under conditions wherein the enzyme reacts with the grain and plant processing by-product; and (e) processing the mixture to create a stable suspension. 2. A process as defined in claim 1, wherein the grain is selected from the group consisting of corn, wheat, barley, millet, oats, and rice. 3. A process as defined in claim 1, further comprising the step of soaking the grain prior to the incubation step. 4. A process as defined in claim 1, further comprising the step of grinding the grain prior to the incubation step. 5. A process as defined in claim 4, wherein the average particle size of the grain is reduced upon grinding to be less than 2000 μm. 6. A process as defined in claim 4, wherein the average particle size of the grain is reduced upon grinding to be less than 850 μm. 7. A process as defined in claim 1, wherein the processed plant by-product is selected from the group consisting of dried distillers grain solubles, condensed beet molasses, whey, and corn steep liquor. 8. A process as defined in claim 1, wherein the enzyme is selected from the group consisting of proteases, keratinases, α-amylases, and starch debranching enzymes. 9. A process as defined in claim 8, wherein the starch debranching enzyme is selected from the group consisting of isoamylase, amyloglucosidase, and pullulanase. 10. A process as defined in claim 1, wherein the ratio of grain to plant processing by-product is between 1:1 and 1:9. 11. A process as defined in claim 1, wherein the suspension has a viscosity between 60-2000 cP at room temperature. 12. A process as defined in claim 1, wherein the suspension remains homogenous for at least four days. 13. A process as defined in claim 1, wherein the processing step comprises high-shear mixing. 14. An animal feed product, comprising a stable, high dry matter suspension of a grain and a plant process by-product that have been enzymatically reacted at a temperature insufficient to gelatinize starch components. 15. An animal feed product as defined in claim 14, wherein the grain is selected from the group consisting of corn, wheat, barley, millet, oats, and rice. 16. An animal feed product as defined in claim 14, wherein the grain has been ground to a flour. 17. An animal feed product as defined in claim 16, wherein the average particle size of the grain is reduced upon grinding to be less than 2000 μm. 18. An animal feed product as defined in claim 17, wherein the average particle size of the grain is reduced upon grinding to be less than 850 μm. 19. An animal feed product as defined in claim 14, wherein the processed plant by-product is selected from the group consisting of dried distillers grain soluble, condensed beet molasses, whey, and corn steep liquor. 20. An animal feed product as defined in claim 14, wherein the enzyme is selected from the group consisting of proteases, keratinases, amylases, and starch debranching enzymes. 21. An animal feed product as defined in claim 20, wherein the starch debranching enzyme is selected from the group consisting of isoamylase, amyloglucosidase, and pullulanase. 22. An animal feed product as defined in claim 14, wherein the ratio of grain to plant processing by-product is between 1:1 and 1:9. 23. An animal feed product as defined in claim 14, wherein the suspension has a viscosity between 60-2000 cP at room temperature. 24. An animal feed product as defined in claim 14, wherein the suspension remains homogenous for at least four days.
