Pigs are very clean animals.
A female pig is called a gilt if she hasn't had piglets
yet and a sow if she has.
Pigs are found on almost every continent except Antarctica.
Pigs can live to be 9-15 years old.
A baby pig is called a piglet.
Pigs live on a farm or in the wild.
They roll around in the mud to cool their skin.
The layer of the dried mud protects their skin from the sun.
A sow can give birth to a litter containing 7 to 12
piglets about twice a year.
A male is called a boar.

A whole group of pigs is called a herd.
