Corn gluten meal is a protein-rich feed containing from 60 to 75% crude protein (DM) (though lower values have been reported). It contains about 15-20% of residual starch in the DM and limited amounts of fibre (crude fibre 1% DM), fat (3% DM) and minerals (2%). Due to its high protein content, corn gluten meal is mostly used as a potential alternative to other plant or animal-based proteins. However, like maize grain, its amino acid profile is low in lysine (1.7% of the protein vs. 6.3% for soybean meal and 7.5% for fish meal) and tryptophan (0.5% vs. 1.4% for soybean meal and 1.1% for fish meal). It also contains more methionine (2.4%) than lysine, resulting in an unbalanced profile for many livestock species, though the relatively good methionine content is valuable for laying hens. Corn gluten meal is also a source of energy, due to its high gross energy content (23.1 MJ/kg DM) and energy digestibility (more than 90% in ruminants and pigs). A constraint is its moderate palatability in land-based livestock. Corn gluten meal is particularly rich in yellow xanthophylls (between 200 and 500 mg/kg DM) that are useful for pigmentation in poultry where high-colour chickens and eggs are prized by consumers.
