Interesting Facts About Pig Intelligence

Pigs are one of the smartest animals in the world, and have been known to rival chimpanzees in some cognitive tests. Pigs are highly trainable, and pick up new information so quickly that piglets have been known to learn their names within the first 2 weeks of age. Pigs also have an excellent memory. Here are 7 interesting facts about pig intelligence:

  1. Pigs are known to be of a similar level of intelligence as a 3 year old child, with their intelligence only surpassed in the animal kingdom by the dolphin, ape, and elephant.
  2. Speaking of intelligence, pigs can recognize themselves in a mirror. This may not sound like much, but even the smartest dog does not understand reflections.
  3. Researchers found that pigs outperform chimpanzees in video games using joysticks. Sounds like a fun study, doesn’t it?
  4. Being highly intelligent, pigs can follow your eye movements or finger pointing to determine what it is you are paying attention to.
  5. Pigs are very social animals and develop preferences for specific herd mates, sleeping next to and spending time with their “friends.”
  6. Wild pigs have been shown to use tools while building their nests – using sticks and large bark as “shovels.”
  7. Pigs have long memories and are curious animals, preferring “new” toys over toys they are already familiar with.

Interesting Facts About Pig Senses

  4. Because of their superior sense of smell, pigs are used by humans to hunt for truffles in North America (truffles referring to mushrooms, not chocolate). 
  5. Pigs have been used to combat war elephants in history. Pigs don’t pose a physical threat to elephants, of course, but their loud shrieks would scare them away.
  6. Pigs have also been used by police forces to sniff out drugs, and by militaries to sniff out land mines.

Interesting Facts About Pig Behavior

Pigs are herd animals with a unique social structure. You can spend hours watching how your pigs interact throughout the day – while sleeping, rooting, and playing with one another. Below are 8 interesting facts about pig behavior:

  1. Pigs are talkative with one another, communicating through squeals and grunts. There have been over 20 distinct vocalizations that researchers have discovered pigs using.
  2. While not known for being especially noisy, a pig will certainly let you know when they are unhappy. Pig squeals can reach up to 115 decibels – louder than a jet engine. (To learn whether your pig is happy or not, check out my article How To Tell If a Pig Is Happy: Top Signs To Look For.)
  3. Pigs like to be clean. They will not soil their sleeping area if given the chance to move around, even as day-old piglets.
  4. Pigs have four toes on each foot, but they only walk on the two middle toes. This gives them the appearance of walking on tip-toes.
  5. Most breeds of pigs will farrow (birth) 8-12 piglets at a time. The Meishan breed, however, can regularly farrow up to 20 piglets at a time.
  6. The gestation period of a pig is 3 months + 3 weeks + 3 days.
