What is corning?
Corn, also known as maize, is one of the most successful cereal grasses of all time. It has been under human cultivation for over 10,000 years and has spread itself into every niche of commercial agriculture. Like most grain producing grasses, corn is an annual that must be replanted each year. While corn originates in the New World, it is grown all over the world and used for a staggering array of products. Corn is far more productive than most cereal crops and able to sustain a higher population than relatives like wheat, rye, or rice. Corn grows in warm weather and usually matures in late summer. The stalks can grow between three feet (one meter) and 20 feet (six meters) tall, depending upon the cultivar. At one point, there were thousands of varieties of corn in production, but these numbers have since dwindled to less than one hundred hardy, predictable varieties with large fleshy kernels. Corn grows in ears, tight clusters of kernels around a central core or cob that is covered in a leafy husk. Corn has been bred in such a way that it has difficulty reproducing without human assistance, thanks to this husk. Archaic forms of corn would be unrecognizable to modern consumers. Corn's ancestor was probably a small grass with ears approximately two inches (five centimeters) long. People determined to eke some sort of nutritional value out of the grass bred corn to the plant we are familiar with today, and it quickly diffused all over the United States. Corn would have been popular among early Americans because it was nutritious, easy to cultivate, tasty, and high yielding. As a commercial crop, corn is everywhere. It is one of the most intensively genetically modified crops, which has led to serious discussion and comment both inside and outside the agricultural industry. Corn is also one of the most grown crops globally, with thousands of acres being dedicated around the world to the high intensity production of corn crops. Corn is also used in everything imaginable. In addition to being eaten straight off the cob or popped, corn is used to manufacture corn syrup, a wildly successful artificial sweetener. Corn is also used to synthesize a number of compounds used in manufacturing processes, such as corn starch, which is in everything from cardboard to biodegradable containers. Corn is extensively cultivated to produce animal feed, with all feedlot animals consuming pounds of the crop each day. In addition, corn is used in the manufacture of alcohol and ethanol, a commonly used alternative fuel.
What do black stallion horses eat?
A black stallion is a horse, and like any other horse, its food needs will depend on its size and work level. Horses eat grass, and in the wild this is the only food they would readily eat. However, in winter, horses will eat hay, bran and chaff. If there is snow on the ground or little grass (or if the grass is dead in summer) they will need supplementary feeding on quality hay. Horses that are being worked will need concentrates to keep their energy up, such as oats, corn or commercial horse feed. The more time a horse spends under saddle (or pulling a plough, or on the lunge line, or working in any other way) the more concentrates it will need to stay in condition. Retired horses, foals and horses that are not under work often do not need concentrates.A stallion is a male horse. Horses eat grasses like oats, wheat, or barley. They graze in open grass lands. Horses do not eat other animals, they are called herbivores.
