What is a baby pig called?

A baby pig is called a "piglet." The collective noun is a "litter" or "farrow" of piglets, and a piglet that has been weaned is called a "shote" or "shoat."

The suffix "-let" is a diminutive, showing that the noun it is attached to is in a smaller form. This can also be seen in words such as "booklet" and "droplet." Pigs can have two litters a year, but the number of piglets produced depends on environmental factors and the breeds of the parents. Typically, large pigs breeding in optimum settings can have an average of eight to 12 piglets in one litter.
