A bull is an intact (i.e., not castrated) adultmale of the species Bos taurus (cattle). More muscular and aggressive than the female of the species, the cow, the bull has long been an important symbol in many cultures, and plays a significant role in both beef and dairy farming, and in a variety of other cultural activities.
Nomenclature
The female counterpart to a bull is a cow, while a male of the species which has been castrated is a steer, ox[1] or bullock, although in North America this last term refers to a young bull, and in Australia to a draught animal.
