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.
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.
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 have been disbudded. (It is true, however, that in many breeds of sheep only the males have horns.) Cattle that naturally do not have horns are referred to as polled, or muleys. [8]
The question is do female reindeer have antlers too, ... It is necessary for females in this family to have horns to defend their food source. ... They are referred to as "bulls" and "cows," just ...
Presence of weapons in females, and female-female competition has been seen in many species for better fitness of both sexual and social selection. [ 25 ] [ 24 ] Social selection, first hypothesized by Mary Jane West-Eberhard , is a broader term that includes both sexual and non sexual behaviors to increase an individual's fitness. [ 24 ]
Male antlers grow more branching points and measure anywhere between 39 inches and 53 inches in beam length, whereas female antlers only measure about 20 inches and generally have a simpler structure.
In all cattle species, a female twin of a bull usually becomes infertile due to intrauterine exposure to high testosterone levels. She is functionally a partial intersex, and is commonly called a freemartin. A wild, young, unmarked bull is known as a micky in Australia. [7] An unbranded bovine of either sex is called a maverick in the US and ...
As soon as young males start developing horns (at around seven to nine months of age), they are chased out of the herd by territorial bulls. These males then form bachelor herds and may roam in female home ranges. [4] Females have home ranges stretching over 200–600 hectares (0.77–2.32 sq mi; 490–1,480 acres).
