Domestic turkey in the context of "Turkey (bird)"

Poultry (/ˈpoʊltri/) are domesticated birds kept by humans for the purpose of harvesting animal products such as meat, eggs or feathers. The practice of raising poultry is known as poultry farming. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes (which includes chickens, quails, and turkeys). The term also includes waterfowls of the family Anatidae (ducks and geese) but does not include wild birds hunted for food known as game or quarry.

Recent genomic studies involving the four extant junglefowl species reveals that the domestication of chicken, the most populous poultry species, occurred around 8,000 years ago in Southeast Asia. This was previously believed to have occurred around 5,400 years ago, also in Southeast Asia. The process may have originally occurred as a result of people hatching and rearing young birds from eggs collected from the wild, but later involved keeping the birds permanently in captivity. Domesticated chickens may have been used for cockfighting at first and quail kept for their songs, but people soon realised the advantages of having a captive-bred source of food. Selective breeding for fast growth, egg-laying ability, conformation, plumage and docility took place over the centuries, and modern breeds often look very different from their wild ancestors. Although some birds are still kept in small flocks in extensive systems, most birds available in the market today are reared in intensive commercial enterprises.

Agriculture in Mexico has been an important sector of the country’s economy historically and politically even though it now accounts for a very small percentage of Mexico’s GDP. Mexico is one of the cradles of agriculture with the Mesoamericans developing domesticated plants such as maize, beans, tomatoes, squash, cotton, vanilla, avocados, cacao, and various spices. Domestic turkeys and Muscovy ducks were the only domesticated fowl in the precolumbian era, and small dogs were also raised for food. There were no large domesticated animals, such as cattle or pigs.

During the early colonial period, the Spanish introduced more plants and the concept of animal husbandry, principally cattle, horses, donkeys, mules, goats and sheep, and barnyard animals such as chickens and pigs. Farming from the colonial period until the Mexican Revolution was focused on large private properties. After the Revolution, these were broken up and the land redistributed. Since the latter 20th century NAFTA and economic policies have again favoured large scale commercial agricultural holdings.
