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.
Their horns can grow up to 3-4 feet across in length and have a unique pattern that's different for every cow, very similar to our fingerprints. They use their horns to dig through snow and grass.
General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur. In many countries, bovid milk and meat is used as food by humans. Cattle are kept as livestock almost everywhere except in parts of India and Nepal, where they are considered sacred by most ...
Polled strains have been developed of many cattle breeds which were originally horned. This has usually been done by crossing with naturally polled breeds, most commonly Angus and Galloway cattle. For example, polled Jersey cattle originated in Ohio sometime prior to 1895. Two strains were developed, the first to appear being founded by crosses ...
A fold of semi-wild Highland cattle was studied over a period of 4 years. It was found that the cattle have a clear structure and hierarchy of dominance, which reduces aggression. Social standing depends on age and sex, with older cattle being dominant to calves and younger ones, and males dominant to females.
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.
The question is do female reindeer have antlers ... females in this family to have horns to defend their food source. ... and "cows," just like cattle or elk. So, a female reindeer is called a cow
[27] [8] Furthermore, not all species of bovin look like cattle, such as the saola which looks more like antelope (a fact that caused some confusion among bovid biologists [21]). What all bovins or wild cattle do have in common is both sexes have the presence of smooth horns, instead of annulated horns seen in most other bovids.
