An "intact" (i.e., not castrated) adult male is called a bull. A father bull is called a sire with reference to his offspring, such as in the herd book or purebred records.

Cow with calf (standing behind her, parts of its body creating the illusion of supernumerary teats "on" the mother). The cattle are generally small, with weights in the range 360–550 kg (800–1200 lb) for bulls and 270–360 kg (600–800 lb) for cows; in the past there was a still smaller or dwarf type within the breed, known as the Guinea, which weighed about 230 kg (500 lb) or less.
The oxen, both male and female, were invariably worked in pairs, yoked with a type of neck yoke. Today Chianina oxen are rarely seen in Italy other than at public events such as the Palio di Siena. In North America Chianina oxen are trained for participation in ox-pulling contests. Conroy shows a pair pulling 6,045 kg (13,327 lb) on a stoneboat.
