Ear Tag - Other Forms of Animal Identification

Other Forms of Animal Identification

Pigs, cattle and sheep are frequently earmarked with pliers that notch registered owner and/or age marks into the ear. Mares on large studs have a plastic tag attached to a neck strap for identification. Valuable animals, such as stallions, usually have a brass name plate on their headcollar during transportation. Dairy cows are sometimes identified with ratchet fastened plastic anklets fitted on the pastern for ready inspection during milking. Laboratory rodents are often marked with ear tags, ear notches or implantable microchips.

The National Livestock Identification System (NLIS) Australia, formerly used cattle tail tags for property identification and hormone usage declaration.
