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. [47] Females possess horns only in half of the bovid genera, and females in these genera are heavier than those in the rest.
This practice is called horn tipping; it is less stressful on the animal because there is no blood loss and the horn is cut off where there are no longer any nerve endings. [6] This practice does not eliminate the bruising damage done by the horns when cows fight, but it does eliminate the risk of puncture wounds and eye loss from pointed horns.
Giraffidae: Giraffids have a pair of skin covered bony bumps on their heads, called ossicones. Cervidae: Most deer have antlers, which are not true horns due to lacking a bone core and made of keratin. Rhinocerotidae: The "horns" of rhinos are made of keratin and lack a bone core.
Polled livestock are preferred by many farmers for a variety of reasons, the foremost being that horns can pose a physical danger to humans, other livestock and equipment. Horns may also interfere with equipment used with livestock (such as a cattle crush), or they may become damaged during handling.
A female bovine that has not yet had a calf is known as a heifer. An adult female that has had her first calf (or second calf, depending upon regional usage) is called a cow. Steers and heifers can sometimes be colloquially referred to as "cows," especially by non-agricultural people who are not familiar with the appropriate terminology.

Horns usually have a curved or spiral shape, often with ridges or fluting. In many species, only males have horns. Horns start to grow soon after birth and continue to grow throughout the life of the animal (except in pronghorns, which shed the outer layer annually, but retain the bony core). Partial or deformed horns in livestock are called scurs.
