Sustained price increase for traditional feed ingredients like cereal grains, protein meals and other feed commodities is pushing the animal nutritionist to find less expensive and safe alternatives. Corn is the major feed ingredient both for livestock and poultry but its demand for human food, biofuel and bioindustrial products is increasing its cost and also the availability of its by-products. Corn germ meal (CGM) is a by-product from corn industry obtained after extraction of corn oil and has nutritional characters (with medium energy and protein) for inclusion in livestock and poultry feeds. Nutritional value of CGM is strongly influenced by method of oil extraction apart from the effect of type of corn used. The main limiting factor to use CGM at higher quantities in animal or poultry diets is its high fibre, oil and phytate contents. Many researches have been conducted in Brazil and other parts of the world where the availability of CGM is high due to corn processing industries on its level of inclusion in the diets of cattle, sheep, pigs and poultry and its effect on their production performances. In India corn industry is gaining importance resulting in production of CGM in appreciable quantities. In this regard a review has been under taken here on the recent studies and findings on nutritive value of CGM, level of inclusion in livestock and poultry diets.
