Of all the grain commonly used in Live Stock & Poultry, Corn is by far the most important. Corn is palatable, readily digested by human and Monogastric and ruminant animals and is one of the best source of Metabolizeable Energy (ME) among the Grains.

Corn is composed of four principal ingredients viz. Starch (Carbohydrate), Gluten (Proteinous material), Fat (Lipids) and Fibers (Cellulosic Material) and providing valuable feed ingredients to produce high quality Live Stock and Poultry. The Co-product of Corn refining forms 25% to 30% of Corn processed and goes into feed product. There are four main Co-products obtained viz. Corn Gluten Meal, Gluten Feed, Corn Germ Meal and Corn steep extracts as can be seen from schemstic outline of Corn-wet milling process FIGURE - 1.

Corn Gluten Meal is prepared by recentrifugation, filtering and drying of gluten slurry obtained in starch gluten separation in the mill.

It has a high protein, high nutrient density, high energy ingredient consisting of insoluble protein in combination with minimal quantity of starch and fiber fractions. This high protein concentrate is commonly provided at minimum 62% protein. It is highly digestible, contains ME 4131 K Cal/Kg. on D.B. for chicks and rich source of available Carotene 49-72 mg/Kg. and Xanthophyll 244-550 mg/Kg.
