Ear punching is commonly used for identification of rodents and involves using a special punch to either produce a small (0.5 to 2 mm) notch near the edge or to punch a hole in the middle of the ear. Before using an ear punch, it should be tested to make sure it works properly. The cutting edge of the punch should be disinfected or the entire punch should be autoclaved.
