Pigs *are* ungulate animals, though, according to this website: http://basicbiology.net/animal/mammals/ungulate/
Ungulate species are separated into two orders: Perissodactyla and Artiodactyla. The Perissodactyls are commonly known as the odd-toed ungulates and includes horses, rhinos, and tapirs. The Artiodactyla consists of the even-toed ungulates and is a much larger order with around 220 different species. Cows, sheep, goats, buffalos, deer, giraffes, pigs, and camels are just a few of the many even-toed ungulates that currently exist on Earth.
