Is a cud chewing mammal called a bovine?

Cud chewing animals are typically called ruminants. Bovines are a special category of ruminants... the Word comes from the Latin Bos which means "ox", and it technically means any member of the family Bovinae, which includes cattle, oxen, bison, buffalo, and certain kinds of antelope.

In common usage, "bovine" essentially means "of or relating to cows" as distinct from sheep (ovine) or horses (equine).
