Cattle Family

Bovids include hoofed animals that have horns, such as sheep, goats and bison. There is a difference between antlers and horns. Antlers are bony structures that are grown each year and are shed. Horns are a solid, bony core, which is part of the animal's skull. Horns are not shed.

Two of the five main types of wild sheep are found in North America—the thinhorn sheep of the north and the bighorn sheep of the south.
