Interior: Baby Bottle (must be a suckling pig!)
Domesticated around 7000 BC. First animals to be used domestically.
Introduced to North America in 1539 by Hernando de Soto.
Live on every continent in the world except Antarctica.
Largest population in China.
Very intelligent. Thought to be fourth smartest animal after humans, primates, and dolphins/whales. Considered by many experts to be more trainable than dogs.
Very clean. They use specific areas in their pen for bathrooms and never soil their living quarters. Would rather stay clean, but they are forced to wallow in mud because they have no sweat glands. Mud helps keep them cool. Mud also protects skin from sunburn. They and light-haired horses are the only animals that can get sunburn.
Have 15,000 taste buds, more than any other mammal, including humans.
On average, eat five pounds of food daily, which is a ton of food annually.
The largest on record weighed 2,552 pounds, named Big Bill and measuring 5 feet high and 9 feet long.
Have well developed sense of smell. They can find things underground and have been used in truffle searches and to sniff out drugs in service to policemen.
Their squeal can be louder than the sound of a supersonic Concorde – up to 115 decibels.
A sow typically gives birth to 6-12 piglets and may have more than one litter per year. There is a sow on record that gave birth to 37 piglets. The gestation period is 3 months, 3 weeks and 3 days, or 115 days in total. The average weight of a newborn is 3 pounds.
A human seldom gets sick from being around them, but humans can give pigs such diseases as influenza, ring worm and hoof and mouth disease from the bacteria on our skin.
Live for 9 to 15 years.
