Earmark (agriculture)

An earmark is a cut or mark in the ear of livestock animals such as cattle, deer, pigs, goats, camels or sheep, made to show ownership, year of birth or sex.

The term dates to the 16th century in England.^[1] For example, in a case of defamation in King's Bench in 1541, the defamatory statement included "George Butteler hath eremarked a mare of one Robert Hawk."^[2] The practice existed in the Near East up to the time of Islam. Against this, in Q. 4:119 the Qur'an quotes the Devil promising, ""I will mislead them, I will entice them, I will command them to mark the ears of livestock, and I will command them to distort the creation of God."^[3]

Earmarks are typically registered when a stock owner registers a livestock brand for their use. There are many rules and regulations concerning the use of earmarks between states and countries. Tasmanian sheep and cattle must be earmarked before they become six months old.^[4]

Generally the owner’s earmark is placed in a designated ear of a camel or sheep to indicate its gender. Typically if a registered earmark is used, it must be applied to the right ear for ewes and the left ear for female camels. The other ear of a sheep then may be used to show the year of its birth. Cattle earmarks are often a variety of knife cuts in the ear as an aid to identification, but it does not necessarily constitute proof of ownership.

Since the 1950s it has been more common to use ear tags to identify livestock because coloured tags are capable of conveying more information than earmarks. Such ear tags were popularised by New Zealand dairy farmers in the earliest successful use of them.^{[citation needed]}

Because of the ubiquity of earmarking, in the nineteenth and twentieth centuries, it became common parlance to call any identifying mark an earmark. In early times many politicians were country or farming folk and were adept at using such words in different ways and in creating new concepts.

Today it is common to refer to an institution's ability to designate funds for a specific use or owner as an earmark.
