1. Zea mays, a tall cereal plant that produces kernels on large ears and is the source of corn oil.
2. a circumscribed, conical, horny induration and thickening of the stratum corneum that causes severe pain by pressure on nerve endings in the corium. Corns are always caused by friction or pressure from poorly fitting shoes or hose. There are two kinds: the hard corn, usually located on the outside of the little toe or on the upper surfaces of the other toes; and the soft corn, found between the toes, usually the fourth and fifth toes, kept softened by moisture. Called also heloma.
corn oil a refined fixed oil obtained from the corn plant, Zea mays; used as a solvent and vehicle for medicinal agents and as a vehicle for injections. It has also been promoted as a source of polyunsaturated fatty acids in special diets.
corn oil(kōrn oyl),
The refined fixed oil expressed from the embryo of Zea mays (family Gramineae); a solvent.

1. a circumscribed hyperkeratosis of the footpad of dogs, sensitive to pressure.
2. a hematoma between the sensitive laminae and horn of the sole, usually between the frog and bar, in the hoof of the horse. It is painful on pressure and a cause of lameness.
3. in USA and elsewhere Zea mays, a member of the plant family Poaceae, grown as a cereal crop bearing seeds and used as a grain feed, green chop and ensilage. Used also for human consumption as meal or flour. The grain is deficient in most essential amino acids, especially lysine and tryptophan (high-lysine varieties are available), and in calcium and cannot be used as a complete ration in pigs. It may be fed whole, cracked, flaked, roasted, as dried or as high moisture corn (contains 25% moisture). Overeating of the grain by ruminants causes carbohydrate engorgement, and of moldy standing corn causes moldy corn poisoning. Called also maize.
4. in UK triticum aestivum is also called corn.
5. the name corn is also used with other cereals such as rye corn, barley corn.
see cob (2). Ground into a meal it is used as a roughage of very low nutritive value in ruminant diets. Of some value as a diluent in high grain diets.
rich source of unsaturated fatty acids, particularly linoleic acid.
