Cattle

Cattle (called cows in vernacular usage) 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 draught animals (pulling carts, plows and the like). In some countries, such as India, they are subject to religious ceremonies and respect. It is estimated that there are 1.3 billion head of cattle in the world today [1].
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 these three have increasingly been grouped as one species, sometimes using the names Bos primigenius taurus, Bos primigenius indicus and Bos primigenius primigenius. 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, banteng, gaur, and bison, 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. (See aurochs for the history of domestication, and zebu for peculiarities of that group.)

Terminology

Texas LonghornThe word "cattle" did not originate as a name for bovine animals. It derives from the Latin caput, head, and thus originally meant "unit of livestock" or "one head". The word is closely related to "chattel" (a unit of property) and to " capital" in the sense of "property."
Older English sources like King James Version of the Bible refer to livestock in general as cattle, or sometimes the archaic kine (which comes from the same English stem as cow). Additionally other species of the genus Bos are often called cattle or wild cattle. This article refers to the common modern meaning of "cattle", the European domestic bovine.
Young cattle are called calves. A young male is called a bull-calf; a young female before she has calved is called a heifer (pronounced "heffer"). Male cattle bred for meat are castrated unless needed for breeding. The castrated male is then called a bullock or steer, unless kept for draft purposes, in which case it is called an ox (plural oxen), not to be confused with the related wild musk ox. If castrated as an adult, it is called a stag. An intact male is called a bull. An adult female over two years of age (approximately) is called a cow. The adjective applying to cattle is bovine.
The term cattle itself is not a plural, but a mass noun. Thus one may refer to some cattle, but not three cattle. There is no singular equivalent in modern English to cattle other than the various gender and age-specific terms (though "catron" is occasionally seen as a half-serious proposal). Strictly speaking, the singular noun for the domestic bovine is ox: a bull is a male ox and a cow is a female ox. That this was once the standard name for domestic bovines is shown in placenames such as Oxford. But "ox" is no longer used in this general sense, being restricted to the sense given above. Today "cow" is probably the closest to being gender-neutral, although it is usually understood to mean female (females of other animals, such as whales or elephants, are also called cows). To refer to a specific number of these animals without specifying their gender, it must be stated as (for example) "ten head of cattle."
Some Australian, Canadian, New Zealand and Scottish farmers use the term "cattlebeast". Obsolete terms for cattle include "neat" (horned oxen, from which " neatsfoot oil" is derived), "beef" (young ox) and "beefing" (young animal fit for slaughtering). 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 word "cow" can also be used derogatively, when describing a person, whom one expresses a dislike for. In some countries, such as the UK, this slur is used exclusively for women whereas in others it may be used for both genders. The word "heifer" is sometimes used in a similar fashion, the implication being that the target of the term is overweight.
Biology

The cud is then reswallowed and further digested by specialized bacterial, protozoal and fungal microbes that live in the rumen. These microbes are primarily responsible for generating the volatile fatty acids (VGAs) that cattle use as their primary metabolic fuel. The microbes that live inside of the rumen are also able to synthesize amino acids from non-protein nitrogenous sources such as urea and ammonia. These features allow them to thrive on grasses and other vegetation.
Cattle have one stomach, with four compartments. They are the rumen, reticulum, omasum, and abomasum. The rumen is the largest compartment and the reticulum is the smallest compartment. Cattle sometimes consume metal objects which are deposited in the reticulum, and this is where hardware disease occurs. The reticulum is known as the "Honeycomb." The omasum's main function is to absorb water and nutrients from the digestible feed. The omasum is known as the "Many Plies." The abomasum is most like the human stomach; this is why it is known as the "True Stomach."
The aurochs was originally spread throughout Europe, Africa, and 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 the original gene pool of the aurochs by careful crossing of commercial breeds, creating the Heck cattle breed.
A popular misconception about cattle (primarily bulls) is that they are enraged by the colour red. This is incorrect, as cattle are mostly colour-blind. This rumour derives from bullfighting, where Matadors traditionally use red-coloured capes to provoke bulls into attacking. The red colour is merely traditional, as the movement of the cape is the attractant.
Uses of cattle
Cow with calfCattle occupy a unique role in human history. Some consider them the oldest form of wealth. Their ability to provide meat, dairy and draft while reproducing themselves and eating nothing but grass has furthered human interests dramatically through the millennia.
In Hinduism, the cow is said to be holy (and thus should not be eaten); "The cow is my mother. The bull is my sire.". [2] The importance of the cow is highlighted by the fact that a regional holiday called Mattu Pongal (literally Cow Pongal in Tamil) exists which is akin to a bovine thanksgiving day. In fact a divine cow named Kamadhenu is considered to be the mother of all Hindu Gods. It is common to see loose cattle walking the streets, because the holiness it holds in India and other countries that practice Hinduism.
In Latin America, Australia and the western North America cattle are grazed on large tracts of rangeland called ranchos, ranches or Stations (Australia).
In Portugal, Spain and some Latin American countries, bulls are used in the sport of bullfighting while a similar sport Jallikattu is seen in South India; in many other countries this is illegal. Other sports like Bull riding are seen as part of a Rodeo, especially in North America.
The outbreaks of mad cow disease have reduced or prevented some traditional uses of cattle for food, for example the eating of brains or spinal cords.
Ox
Draft Zebus in Mumbai, India.Oxen (plural of ox) are cattle trained as draft animals. Often they are adult, castrated males. Usually an ox is over four years old due to the need for training and for time to grow to full size. Oxen are used for plowing, transport, hauling cargo, grain-grinding by trampling or by powering machines, irrigation by powering pumps, and wagon drawing. Oxen were commonly used to skid logs, and sometimes are still in low-impact select-cut logging, in forests.
Contrary to popular American lore, an "ox" is not a unique breed of bovine, nor have any "blue" oxen lived outside the folk tales surrounding Paul Bunyan, the mythical American logger.
An ox is nothing more than a mature bovine with an "education". The education consists of the animal's learning to respond appropriately to the teamster's (ox driver's) commands: in North America such as (1) get up, (2) whoa, (3) back up, (4) gee (turn to the right) and (5) haw (turn to the left).
American ox trainers favored larger breeds for their ability to do more work in addition to their intelligence (the ability to learn); for the same reason, the typical ox is the male of a breed, rather than the smaller female. Also, the gait of the ox is often important to ox trainers, since the speed the animal walks should roughly match the gait of the ox driver who must work with it.
Oxen are most often used in teams of two, paired, for light work such as carting. In past days some teams were about fourteen, and even over twenty for logging. A wooden yoke is fastened about the neck of each pair so that the force of draft is distributed across their shoulders. Oxen are chosen, from calves, with horns since the horns hold the yoke in place when the oxen lower their heads, back up or slow down (particularly with a wheeled vehicle going downhill). Yoked oxen cannot slow a load like harnessed horses can, the load has to be controlled downhill by other means.
Oxen must be painstakingly trained from a young age. Their teamster must make or buy as many as a dozen yokes of different sizes as the animals grow. Ox teams are steered by commands or noise (whip cracks) and many teamsters were known for their voices and language.
Oxen can pull harder and longer than horses, particularly on obstinate or almost un-movable loads. This is one of the reasons that teams were dragging logs from forests long after horses had taken over most other draught uses in Europe and the New World. Though not as fast as horses, they are less prone to injury because they are more sure-footed and do not try to jerk the load. Many oxen are still in use worldwide, especially in developing nations.
