TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The two process feedstreams include at least two of (i) fatty acids from oil hydrolysis, (ii) lipids from evaporation of thin stillage, (iii) syrup, (iv) distillers grains (DG), (v) distillers grains and solubles (DGS), (vi) solids from a mash before fermentation; (vii) solids from a whole stillage after fermentation, (viii) oil, and (ix) microorganism, where the fatty acids are from corn oil hydrolysis, where DG are dried distillers grains (DDG) or wet distillers grains (WDG), where the DGS are dried distillers grains and solubles (DDGS) or wet distillers grains and solubles (WDGS). The alcohol production process is a butanol production process, where butanol produced in the butanol production process is used as a solvent wash for feedstream of the butanol production process. The process feedstream is (i) fatty acids from oil hydrolysis, (ii) lipids from evaporation of thin stillage, (iii) syrup, (iv) DG, (v) DGS, (vi) solids from a mash before fermentation; (vii) solids from a whole stillage after fermentation; (viii) oil, or (ix) microorganism. The fatty acids are from corn oil hydrolysis. The DG are DDG or WDG. The DGS are DDGS or WDGS. The distillers co-products for animal feed has a crude fat content of less than 10 wt.% of the distillers co-products. The distillers co-products for animal feed has a fatty acid content of less than 10 wt.% of distillers co-products. The protein content of the distillers co-products for animal feed is supplemented with a yeast cell mass, where the yeast cell mass increases the protein content of the distillers co-products for animal feed. The fatty acid content provides additional energy and nutrient for an animal feed composition that comprises the distillers co-products for animal feed. Preferred Composition: The distillers co-products further comprises (wt.%): fatty acids (less than 10 %), fatty acid ester (less than 10 wt.%), and lysine ( not greater than 5 wt.%). The composition has a nutrient profile for cattle, dairy, livestock, swine, poultry, equine, aquaculture, or domestic pet feed market. The distillers co-products further comprises supplementing the distillers co-products for animal feed composition with additional components selected from amino acids, vitamins, minerals, nutrient, flavor enhancer, digestion stimulant, or color enhancer.
