  • 7000 B.C.–The pig was one of the first animals to be domesticated or trained.

Everything But the Oink

  • The amazing utility of the hog has motivated the saying, “We use everything, but the oink.” Thanks to hogs, we have several life-supporting and life-saving products.
  • Swine research led to the development of the CAT scan, a technology for examining internal organs without surgery.
  • Pork fat, especially lard, has a history of being used as a medicine. The lard was combined with herbs as a home remedy for chest congestion.

Pharmaceutical By-products

Hogs are powerful resources!  All told, pigs are a source of nearly forty drugs and pharmaceuticals!

Pharmaceutical Facts

  • Pig pancreas glands are an important source of insulin hormone used to treat diabetes.  Pig insulin is especially important because its chemical structure most nearly resembles that of humans.
  • Specially selected and treated hog skin, because of its similarity to human skin, is used in treating massive burns in humans, injuries that have removed large areas of skin and in healing persistent skin ulcers.
  • Hog heart valves, specially preserved and treated, are surgically implanted in humans to replace heart valves weakened by disease or injury.  Since the first operation in 1971, tens of thousands of hog heart valves have been successfully implanted in human recipients of all ages.

Did You Know…

  • The pork industry supports more than 800,000 jobs.
  • Pork is the world’s most widely eaten meat.
  • Pigs do not have sweat glands, so they use water or mud to cool off.
  • The pig is rated the fourth most intelligent animal.
  • On Manhattan Island, a long solid wall was constructed on the northern edge of the colony to control roaming herds of pigs.  This area is now known as Wall Street.
  • In ancient Crete, it was the custom for each family to raise a hog to be harvested on Christmas Eve and served the next day.  Nearly every part of the pig was consumed, feeding the family for weeks.  The bladder was often washed out, cleaned and used as a ball for children’s games.
  • In many cultures, children are given “piggy banks” to encourage them to save their money.

Pig, wild or domestic swine, a mammal of the Suidae family. In Britain, the term pig refers to all domestic swine; in the United States, to younger swine not yet ready for market and weighing usually less than 82 kg (180 pounds), others being called hogs. Pigs are stout-bodied, short-legged, omnivorous mammals, with thick skins usually sparsely coated with short bristles. Their hooves have two functional and two nonfunctional digits. Domestic North American pigs originated from wild stocks still found in European, Asian, and North African forests. Wild pigs are not truly native to North America but are believed to have been introduced on Christopher Columbus’ second voyage in 1493 and brought to the mainland in the early 1500s. There is little difference between wild pigs, or boars, and domestic swine, though the tusklike teeth of domestic pigs are not as developed as the tusks of their wild kin, who use the sharp ends to forage for roots and as a defensive weapon. Wild pigs may live up to 25 years or more.

Domestic pigs are categorized according to three basic types: large-framed lard types with a comparatively thick layer of fat and carcasses usually weighing at least 100 kg (220 pounds); smaller bacon types, with carcasses of about 70 kg (150 pounds); and pork types with carcasses averaging around 45 kg (100 pounds).

In the early 21th century, China had the largest hog population of any country in the world, but scientific breeding was concentrated in Europe and the United States. Denmark produced the Landrace breed, raised for its excellent bacon. The Yorkshire (Large White), the world’s most popular breed, originated in Britain in the 18th century. In the late 20th century many farmers began raising leaner hogs through the use of both improved feed and selective breeding techniques. See alsolivestock.

A comparison of selected breeds of pigs is provided in the table.
