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.

Famous quotes containing the words forms and/or animal:
“The time will come when the evil forms we have known can no more be organized. Man’s culture can spare nothing, wants all material. He is to convert all impediments into instruments, all enemies into power.”
—Ralph Waldo Emerson (1803–1882)
“Nobody can misunderstand a boy like his own mother.... Mothers at present can bring children into the world, but this performance is apt to mark the end of their capacities. They can’t even attend to the elementary animal requirements of their offspring. It is quite surprising how many children survive in spite of their mothers.”
—Norman Douglas (1868–1952)
