Cattle, colloquially referred to as cows, are domesticated ungulates, a member of the subfamily Bovinae of the family Bovidae. They are raised as livestock for meat (called beef and veal), dairy products (milk), leather and as draft animals (pulling carts, plows and the like). In some countries, such as India, they are honored in religious ceremonies and revered. It is estimated that there are 1.3 billion cattle in the world today.

Species of cattle

Cattle were originally identified by Carolus Linnaeus as three separate species. These were Bos taurus, the European cattle, including similar types from Africa and Asia; Bos indicus, the zebu; and the extinct Bos primigenius, the aurochs. The aurochs is ancestral to both zebu and European cattle. More recently

Complicating the matter is the ability of cattle to interbreed with other closely related species. Hybrid individuals and even breeds exist, not only between European cattle and zebu but also with yaks (called a dzo), banteng, gaur, and bison ("cattalo"), a cross-genera hybrid. For example, genetic testing of the Dwarf Lulu breed, the only humpless "Bos taurus-type" cattle in Nepal, found them to be a mix of European cattle, zebu and yak. Cattle cannot successfully be bred with water buffalo or African buffalo.

The aurochs originally ranged throughout Europe, North Africa, and much of Asia. In historical times, their range was restricted to Europe, and the last animals were killed by poachers in Masovia, Poland, in 1627. Breeders have attempted to recreate cattle of similar appearance to aurochs by crossing of domesticated cattle breeds, creating the Heck cattle breed. (See also aurochs and zebu articles.)

Word origin

Cattle did not originate as a name for bovine animals. It derives from the Latin caput, head, and originally meant movable property, especially livestock of any kind. The word is closely related to "chattel" (a unit of personal property) and "capital" in the economic sense.

Older English sources like King James Version of the Bible refer to livestock in general as cattle (as opposed to the word deer which then was used for wild animals). Additionally other species of the genus Bos are sometimes called wild cattle. Today, the modern meaning of "cattle", without any other qualifier, is usually restricted to domesticated bovines.

Terminology of cattle

An intact (i.e., not castrated) adult male is called a bull. An adult female who has had one or two calves (depending on regional usage) is called a cow. Young cattle are called calves until they are weaned, then weaners until they are a year old in some areas, in other areas, particularly with beef cattle, they may be known as feeder-calves or simply feeders. After that, they are referred to as yearlings or stirks if between one and two years of age, or by gender. A young female before she has had a calf of her own is called a heifer ( , "heffer"). A young female that has had only one calf is occasionally called a first-calf heifer. A castrated male is called a steer in the United States, and older steers are often called a bullock in other parts of the world; although in North America this term refers to a young bull. A castrated male (occasionally a female or in some areas a bull) kept for draft purposes or for food is called an ox (plural oxen). In Australia the term "Japanese ox" is used for grain fed steers in the weight range of 500 to 650kg that are destined for the Japanese meat trade. In North America, draft cattle under four years old are called working steers. Improper or late castration on a bull results in it becoming a coarse steer known as a stag in Australia, Canada and New Zealand. In some countries an incompletely castrated male is known also as a rig. In all cattle species, a female who is the twin of a bull usually becomes an infertile partial intersex, and is a freemartin. Some Australian, Canadian, New Zealand and Scottish farmers use the term cattlebeast.Fact: date=July 2008 Neat (horned oxen, from which neatsfoot oil is derived), beef (young ox) and beefing (young animal fit for slaughtering) are obsolete terms, although poll or polled cattle is still a term in use for naturally hornless animals, or in some areas cattle that have been disbudded. Cattle raised for human consumption are called beef cattle. Within the beef cattle industry in parts of the United States, the older term beef (plural beeves) is still used to refer to an animal of either gender. Cows of certain breeds that are kept for the milk they give are called dairy cows. The adjective applying to cattle in general is usually bovine. The terms "bull", "cow" and "calf" are also used by extension to denote the gender of other large animals, including whales, hippopotamuses, camels, elk and elephants.
