Nutritive Value of Protein in Hominy Feed Fractions.

To ascertain if hominy feed is processed for optimal use as a feed ingredient, compositional analyses and nutritional evaluations were conducted on it and on components produced under different conditions. Hominy feed constitutes 27 to 35% of total dry-milled corn products and consists mainly of bran and bran meal, oil cake, and fine feed composed of degerminator fines and tailing meal. The level of protein in hominy feed (12%) exceeds that of corn (9%). Amino acid analyses conducted on hominy-feed fractions indicate that they contain higher levels of lysine, tryptophan, and other essential amino acids than whole corn or corn grits. However, processing conditions influence the actual nutritional value of protein in hominy-feed fractions. The nutritionally available lysine determined by reaction with 2,4- dinitrofluorobenzene is less than the total lysine of hominy feeds. Rat feeding studies showed differences in protein quality between corn germ processed by expeller to remove oil and germ extracted by solvent. Properly processed hominy feed can serve as a good protein source in nonruminant diets.
