Fact 2: Pigs typically weigh between 50-350 kg and have a body length ranging from 0.9-1.8 meters.

  • Well-fed individuals often exceed this weight range.

Fact 3: Pigs are usually farmed because humans want to eat pork.

  • The animal’s bones, hide, and bristles are also used in commercial products. Domestic pigs, especially miniature breeds, are kept as pets.

Fact 4: Pigs cool off by wallowing in mud or water, which is a process called evaporative cooling.

  • Rolling in mud also protects them from sunburn, ectoparasites, and aids in scent-marking. 

Fact 5: Pigs are one of four known mammalian species which possess mutations that protect against snake venom.

  • Like Mongooses, honey badgers, and hedgehogs they have a modified nicotinic acetylcholine receptor that protects them from poisonous snake venom.

Fact 6: They have small lungs.

  • This makes pigs more susceptible than any other domesticated animal to fatal bronchitis/pneumonia.

Fact 17: Pigs compensate for their poor eyesight with their keen sense of smell.

  • A pig’s nostrils are located on its leathery snout, which is very sensitive to touch. The pig uses the snout to search, or “root” for food.
