Corn Gluten Meal (CGM) is a by-product of corn wet milling process and corn starch production. Corn Gluten Meal is a protein-rich feed, containing about 65% crude protein (DM), used as a source of protein, energy and pigments for livestock species including fish. It is also valued in pet food for its high protein digestibility.
The product is golden yellow in color; and fine granular in its physical appearance. Due to its high protein content, Corn Gluten Meal is mostly used as a source of protein as a potential alternative to other plant or animal-based proteins, such as Soybean Meal, Meat and Bone Meal and Fish Meal.
Corn Gluten Meal is also a source of energy, due to its high gross energy (23.1 MJ/kg DM) coupled with high energy digestibility (> 90% in ruminants and pigs). Corn Gluten Meal is particularly rich in yellow xanthophyll (between 200 and 500 mg/kg DM) that are useful for pigmentation in poultry.
