The ear tag method is divided into two kinds of round and long ear tags. The latter is to put a number on the metal ear tag, and then use the ear clamp to clamp the ear tag in the appropriate place on the upper edge of the ear. When ear tags are attached, care should be taken not to press the ear tags against the edges of the cow's ears, so that the necrosis of the pressed parts will occur and the ear tags will come off. When ear tags are worn for the Mavericks, appropriate gaps should be left for growth.
