There isn't one specific equine word that correlates.
A pig is a swine that hasn't yet come to maturity.
There are different words for immature horses that are broken down by age and gender.
Foal - Baby horse under one year old
Yearling - Young horse that has lived one year (is in it's second year of life)
Filly - Young female horse under the age of four
Colt - Young male horse under the age of four
Please note that it's a common misconception that a pony is a young horse. Pony refers to breed, not age. Ponies are horses that are bred to be under a certain height. A pony is a pony from the day it's born until the day it dies.
ETA: Russ, you are wrong. A pig is a young swine. A piglet is a baby swine.
