Maize or Corn is the most important cereal in the world after wheat and rice; it is also the most widely distributed.
Maize is an outstanding feed for livestock, high in energy, low in fibre and easily digestible. It is an important forage crop, being cut green, or dried for fodder, or made into silage.
Maize is used for three main purposes:
(1) As a staple human food, particularly in the tropics;
(2) As feed for livestock, particularly in temperate and advanced countries, providing over two-thirds of the total trade in feed grains;
(3) As a raw material for many industrial products.
Maize (Zea mays), known as "corn" by most English-speakers, is a cereal grain domesticated in Mesoamerica and subsequently spread throughout the American continents. Corn, also called maize, is a cereal grass related to wheat, rice, oats, and barley. It is a plant whose food value and wide variety of uses make it the most important crop grown in the United States and one of the most important in the world. Corn is raised as source of food and food products for people, livestock feed, and industrial products including ceramics, explosives, construction materials, metal molds, paints, paper goods, textiles, industrial alcohols, and ethanol
When ground into flour, maize yields more flour, with much less bran, than wheat does. However, it lacks the protein gluten of wheat and, therefore, makes baked goods with poor rising capability and coherence. Corn and cornmeal (corn flour) constitutes a staple food in many regions of the world. Corn meal is made into a thick porridge in many cultures. Corn meal is also used as a replacement for wheat flour, to make cornbread and other baked products. Corn is a tall plant grass that has large ears with many seeds or kernels. These seeds grow in rows on the larger ears and are eaten as a vegetable. Corn is grown as food for both people and animals.
Its parts are useful in treating children ailments, especially renal problems. It is good for gonorrhoea, cystitis (inflamation of the bladder), kidney stones, prostatitis, edema, obesity, diabetes, pile, retained placenta and circulatory problems. All parts of the maize are medicinal: corn silk for diabetes; the cob (roasted and ground to powder and added to palm kernel oil) is used in treating hemorrhoids, especially the protruding type.
