Cow in the context of Pet

Domestication is a multi-generational mutualistic relationship in which an animal species, such as humans or leafcutter ants, takes over control and care of another species, such as sheep or fungi, to obtain from them a steady supply of resources, such as meat, milk, or labor. The process is gradual and geographically diffuse, based on trial and error. Domestication affected genes for behavior in animals, making them less aggressive. In plants, domestication affected genes for morphology, such as increasing seed size and stopping the shattering of cereal seedheads. Such changes both make domesticated organisms easier to handle and reduce their ability to survive in the wild.

The first animal to be domesticated by humans was the dog, as a commensal, at least 15,000 years ago. Other animals, including goats, sheep, and cows, were domesticated around 11,000 years ago. Among birds, the chicken was first domesticated in East Asia, seemingly for cockfighting, some 7,000 years ago. The horse came under domestication around 5,500 years ago in central Asia as a working animal. Among invertebrates, the silkworm and the western honey bee were domesticated over 5,000 years ago for silk and honey, respectively.

Milk is a white liquid food produced by the mammary glands of lactating mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) before they are able to digest solid food. Milk contains many nutrients, including calcium and protein, as well as lactose and saturated fat; the enzyme lactase is needed to break down lactose. Immune factors and immune-modulating components in milk contribute to milk immunity. The first milk, which is called colostrum, contains antibodies and immune-modulating components that strengthen the immune system against many diseases.

As an agricultural product, milk is collected from farm animals, mostly cattle, on a dairy. It is used by humans as a drink and as the base ingredient for dairy products. The US CDC recommends that children over the age of 12 months (the minimum age to stop giving breast milk or formula) should have two servings of milk products a day, and more than six billion people worldwide consume milk and milk products. The ability for adult humans to digest milk relies on lactase persistence, so lactose intolerant individuals have trouble digesting lactose.

Dairy products or milk products are food products made from (or containing) milk. The most common dairy animals are cow, water buffalo, nanny goat, and ewe. Dairy products include common grocery store food around the world such as yogurt, cheese, milk and butter. A facility that produces dairy products is a dairy. Dairy products are consumed worldwide to varying degrees. Some people avoid some or all dairy products because of lactose intolerance, veganism, environmental concerns, other health reasons or beliefs.

Nut /ˈnʊt/ (Ancient Egyptian: Nwt, Coptic: Ⲛⲉ), also known by various other transcriptions, is the goddess of the sky, stars, cosmos, mothers, astronomy, and the universe in the ancient Egyptian religion.

She is often depicted as a nude woman covered with stars and arching over the Earth; and sometimes as a cow. Alternatively, she is identified with a water-pot (nw) above her head.

Bos (from Latin bōs: cow, ox, bull) is a genus of bovines, which includes, among others, wild and domestic cattle.

Bos is often divided into four subgenera: Bos, Bibos, Novibos, and Poephagus, but including these last three divisions within the genus Bos without including Bison is believed to be paraphyletic by many workers on the classification of the genus since the 1980s. The genus as traditionally defined has five extant species, but this rises to eight when the domesticated varieties are counted as separate species, and ten when the closely related Bison is also included. Most but not all modern breeds of domesticated cattle (including taurine cattle and zebu) are believed to have originated from the extinct aurochs. Others like Bali cattle and gayal are thought to have originated from South and Southeast Asian Bos species.

A calf (pl.: calves) is a young domestic cow or bull. Calves are reared to become adult cattle or are slaughtered for their meat, called veal, and their hide.

A barn is an agricultural building usually on farms and used for various purposes. In North America, a barn refers to structures that house livestock, including cattle and horses, as well as equipment and fodder, and often grain. As a result, the term barn is often qualified e.g. tobacco barn, dairy barn, cow house, sheep barn, potato barn. In the British Isles and in Europe, the term barn is restricted mainly to storage structures for unthreshed cereals and fodder, the terms byre or shippon being applied to cow shelters, whereas horses are kept in buildings known as stables. In mainland Europe, however, barns were often part of integrated structures known as byre-dwellings (or housebarns in US literature). In addition, barns may be used for equipment storage, as a covered workplace, and for activities such as threshing.

A teat is the projection from the mammary glands of mammals from which milk flows or is ejected for the purpose of feeding young. In many mammals, the teat projects from the udder. The number of teats varies by mammalian species and often corresponds to the average litter size for that animal. In some cases, the teats of female animals are milked for the purpose of human consumption.

The quality of some domesticated animals is determined by the establishment of desired characteristics, such as teat size and placement.

Cowhide is the natural, unbleached skin and hair of a cow. It retains the original coloring of the animal. Cowhides are a product of the food industry from cattle. Cowhide is frequently processed into leather.

There are several figures named Pelagon (Ancient Greek: Πελάγων, -ονος) in Greek mythology.

• Pelagon, king of Phocis and son of Amphidamas. He gave Cadmus the cow that was to guide him to Boeotia.
• Pelagon, also called Pelasgus, son of the river-god Asopus by the naiad Metope, daughter of the river Ladon. He was brother to Ismenus, Corcyra, Salamis, Aegina, Peirene, Cleone, Thebe, Tanagra, Thespia, Asopis, Sinope, Ornea, Chalcis, Harpina and Ismene. His sisters were abducted by various gods as punishment for their father's deed.
• Pelagon, one of the suitors of Hippodamia before Pelops.
• Pelagon, one of the Calydonian hunters.
• Pelagon or Pelegon, who is given in the Iliad as the father of the Paeonian warrior Asteropaeus, son of the river-god Axius and Periboea, the daughter of Acessamenus. Presumably this Pelagon was the eponymous founder of Pelagonia.
• Pelagon, a native of Pylos who fought under Nestor in the Trojan War.
• Pelagon, an "illustrious" companion of the hero Sarpedon during the Trojan War, who removes Tlepolemus' spear from Sarpedon's thigh.

Ornithopoda (/ˌɔːrnəˈθɒpədə/) is a clade of ornithischian dinosaurs, called ornithopods (/ˈɔːrnəθəˌpɒdz, ɔːrˈnɪθ-/). They represent one of the most successful groups of herbivorous dinosaurs during the Cretaceous. The most primitive members of the group were bipedal and relatively small-sized, while advanced members of the subgroup Iguanodontia became quadrupedal and developed large body size. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex of diversity and ecological dominance in the hadrosaurids (colloquially known as 'duck-bills'), before they were wiped out by the Cretaceous–Paleogene extinction event along with all other non-avian dinosaurs. Members are known worldwide.

Boötes (/boʊˈoʊtiːz/ boh-OH-teez) is a constellation in the northern sky, located between 0° and +60° declination, and 13 and 16 hours of right ascension on the celestial sphere. The name comes from Latin: Boōtēs, which comes from Ancient Greek: Βοώτης, romanized: Boṓtēs 'herdsman' or 'plowman' (literally, 'ox-driver'; from βοῦς boûs 'cow').

One of the 48 constellations described by the 2nd-century astronomer Ptolemy, Boötes is now one of the 88 modern constellations. It contains the fourth-brightest star in the night sky, the orange giant Arcturus. Epsilon Boötis, or Izar, is a colourful multiple star popular with amateur astronomers. Boötes is home to many other bright stars, including eight above the fourth magnitude and an additional 21 above the fifth magnitude, making a total of 29 stars easily visible to the naked eye.
