Agriculture: Farming, Ranching playlist: https://www.youtube.com/playlist?list=PL897E774CDB19F283 more at http://quickfound.net/links/agriculture_news_and_links.html A pig farm gets the usual Frith treatment, narrated by Don McNamara. Reupload of a previously uploaded film with improved video & sound. Public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ http://en.wikipedia.org/wiki/Domestic_pig The domestic pig (also swine, in some areas hog) is a large domesticated land mammal that traces its ancestry to the wild boar, and is considered a subspecies of the wild boar or a distinct species in its own right. It is likely the wild boar was domesticated as early as 13,000 BC in the Tigris River basin. Pigs are farmed for the consumption of their flesh; however, some cultures have religious dietary laws that forbid the consumption of pork, which is the name for pig meat. The animal's bones, hide, and hair have been fashioned into items such as brushes. Pigs, notably the pot-bellied pig, are also kept as pets. Miss Piggy, Babe, and Porky the Pig represent the domestic pig in entertainment and "The Three Little Pigs", Charlotte's Web, and The Sheep-Pig are prominent examples of the domestic pig in literature. Description Most domestic pigs have rather sparse hair covering on their skin, although woolly coated breeds, such as the Mangalitsa, are raised. The domestic pig is most often treated as a subspecies of its wild ancestor, the wild boar, which was given the name Sus scrofa by Carl Linnaeus in 1758, in which case its formal name is Sus scrofa domesticus. In 1777, Johann Christian Polycarp Erxleben treated the domestic pig as a separate species from the wild boar. He gave it the name Sus domesticus, which is still used by some taxonomists to this day. Wild boars were in human association as early as 13,000--12,700 BC. Escaped domestic pigs have become feral in many parts of the world (for example, New Zealand) and have caused substantial environmental damage. Since the domestic pig is a major domesticated animal, it is known by many names. A "boar" is a male domesticated pig. A castrated male pig is called a "barrow". A "sow" is a female pig. A sow may "farrow" (verb) a litter of "piglets", which is described as a "farrow" (noun). A female pig that has never been pregnant is called a "gilt". Anything resembling or anything characteristic of pigs is known as "porcine", and the breed may be either "swine", or "pig", whereas larger specimens are typically "hogs". In Old and Middle English, the "pig" was originally reserved for small, young swine... The domestic pig is mostly used for its meat, pork. Other food products made from pigs include pork sausage (made from the intestines), bacon, gammon, ham and pork scratchings (made from the hide or rind). The head of a pig can be used to make a preserved jelly called head cheese (brawn). Liver, chitterlings, blood (blood pudding or black pudding) and other offal from pigs are also widely used for food. In some religions, such as Judaism and Islam, pork is taboo food because there are religious restrictions on the consumption of pork... In developing nations, and often in developed nations, the domestic pig is a native species raised outdoors in yards or fields. In some cases pigs are allowed to forage in woods, where they may be watched by swineherds. In industrialized nations, domestic pig farming has shifted away from the traditional pig farm to large-scale intensive pig farms. This has resulted in lower production costs, but significant animal welfare concerns. Pigs are particularly valued in China and on certain oceanic islands, where their self-sufficiency allows them to be turned loose, although the practice is not without its drawbacks. With managed rotational grazing techniques pigs can be raised in an environmentally sound manner on pasture much like grazing sheep, goats and cows without high grain inputs...
