Further Information about Corn (Maize) Production and Products Corn (Maize) is a coarse, quick‐growing, annual cereal grass up to 2.5m high, with long, broad strap‐shaped leaves, native to South America, but now widely cultivated all over the world. It can be cultivated in all climates where the summers are long and warm enough to permit the grains to ripen. There are many varieties of maize. Flint maize, or round maize, and dent maize or horse‐ tooth maize are the two most commonly used for animal feeding. More recent varieties are hybrid maize and high‐lysine (opaque‐2) maize. All types of maize grain should be ground before feeding. Even for poultry it is necessary to crush the grains before feeding. Maize meal cannot be stored for long, because it is likely to become rancid. Dried grains have a better keeping quality. A cheaper way to store maize is to ensile the fresh grains in a trench silo. The moisture content of the grain should be 30% and it should be crushed before ensiling. When maize is dry‐milled to provided maize flour, the bran and the germ are first separated
