A member of the artiodactyl family. Members of this family have unbranched horns comprising a layer of keratin surrounding a bony core. These horns are never shed, as opposed to the antlers of deer. Bovids also have divided ("cloven") hooves and chew their cud (utilizing a 4-chambered ruminating stomach). Bovids include cattle, oxen, bison, buffaloes, sheep, goats and antelopes (which include gazelles).
A bovid is any of almost 140 species of cloven-hoofed mammals belonging to the family Bovidae. The family is widespread, being native to all continents except South America, Australia and Antarctica, and diverse: members include buffalo, bison, antelopes, gazelles, and both wild and domesticated cattle, sheep, goats, and water buffalo.
