PROCESS FOR THE PRODUCTION OF ANIMAL FEED AND ETHANOL AND NOVEL ANIMAL FEED
First Claim
1. A method for obtaining ethanol and stillage from corn comprising the steps of:
- removing the pericarp from corn kernels;
removing the germ from said corn, resulting in a starch and a protein;
separating said protein from said starch;
liquefying and saccharifying and fermenting said starch to produce a fermented starch broth; and
distilling said fermented starch broth to obtain ethanol and stillage.

Abstract
A method for the production of ethanol and a modified animal feed is provided. The method replaces the starch in known corn-based animal feed with biomass fiber treated to make it more digestible by animals. The process includes wherein the pericarp and germ are removed from the corn kernel and processed for by-products. The starch and protein are also removed and separated. The starch is then fermented and distilled to ethanol and stillage. The bioavailable modified animal feed comprises the pericarp and germ removed from corn kernels and optionally by-products of the pericarp and germ processing, and lignocellulosic materials. The modified animal feed may optionally include energy materials such as animal and vegetable fats, vegetable soapstocks, or glycerin, and combinations thereof.

15. A method of producing a bioavailable feedstock comprising the steps of
removing the pericarp from corn kernels; -
removing the germ from said corn kernels, resulting in a starch and a protein; separating said protein from said starch; liquefying and saccharifying and fermenting said starch to produce a fermented starch broth; removing fermentation solids from said fermented starch broth; pretreating a biomass fiber comprising one or more plant-derived lignocellulosic materials, agricultural processing residues, or by-products, and combinations thereof to enhance digestibility thereof for a ruminant; mixing said pretreated lignocellulosic materials, agricultural processing residues or by-products with said fermentation solids; mixing said removed pericarp and said removed germ with said mixed pretreated lignocellulosic materials or agricultural processing residues or by-products and fermentation solids to produce a bioavailable feedstock.
