The horns of female bovids are believed to have evolved for defence against predators or to express territoriality, as non-territorial females, which are able to use crypsis for predator defence, often do not have horns.

It is not true, as is commonly believed, that bulls have horns and cows do not: the presence of horns depends on the breed, or in horned breeds on whether ...
The horns are unusually large, with a wide spread [2]: 110 and the largest circumference found in any cattle breed. Guinness World Records lists a bull named CT Woodie with a horn circumference of 103.5 cm (40.7 in) and a steer named Lurch, with horns measuring 95.25 cm (37.50 in), as record-holders.
