By: 1. They Know Their Names
Piglets begin recognising their mother’s voice within days of birth and can learn to respond to their own names remarkably quickly. Researchers have observed sows communicating with their young using distinctive vocalisations, creating one of the strongest parent-offspring bonds found in farm animals.
2. They’re Faster Than You Think
Despite their stocky appearance, pigs are surprisingly athletic. Adult pigs can reach speeds of around 11mph (18km/h) — fast enough to complete a seven-minute mile and leave many casual runners struggling to keep up.
3. They’re Incredibly Clean
Contrary to popular belief, pigs are naturally clean animals. Given enough space, they will separate sleeping, feeding and toilet areas. Their famous mud baths are less about being dirty and more about staying cool, protecting skin from sunburn and deterring parasites. Click here to learn more about pig anatomy!
4. They can be Surprisingly Loud
A pig's squeal can be as loud as 115 decibels – that’s 3 decibels higher than the sound of a supersonic airliner.
5. They Talk to Each Other Constantly
When they’re not squealing, they’re talking. Pigs communicate constantly with each other, and more than 20 different vocalisations have been identified; from wooing a mate to saying ‘I’m hungry!”
6. They are not Fussy Eaters
Pigs will eat almost anything – including human bones. In 2012, a farmer in Oregon, America, was eaten by his pigs after having a heart attack and falling into their enclosure. By the time a concerned relative came looking for him, only his dentures were left. To learn more about pig nutrition, click here.
7. They Love to Socialise
Pigs are highly intelligent and incredibly social animals. When kept in a group they will snuggle close to one another, and prefer to sleep nose-to-nose. Click here to learn more about group-housing of sows and why it's important to get it right!
8. Their Sense of Smell Is Extraordinary
A pig’s nose is an extraordinary sensory tool. Their powerful sense of smell helps them locate food, identify other pigs and navigate their surroundings. In some countries, pigs have even been trained to find truffles hidden underground.
9. They Experience Dreams
Like humans and many other mammals, pigs experience REM (rapid eye movement) sleep. During this stage, scientists believe pigs dream, process memories and support healthy brain function.
10. They Have Distinct Personalities
Just like people, pigs have unique personalities. Some are bold and adventurous, while others are cautious and reserved. Understanding these individual differences is an important part of modern animal welfare and management.
