Ear Tagging and Notching

Mice can be ear tagged or notched as a permanent means of identification. Serially numbered stainless steel tags are available that can be applied to one ear of the ear mouse using a specialized applicator. Alternatively ears can also be notched according to a standard numbering scheme (see image) using an ear punch. Both of these procedures can be performed without anesthesia and cause only momentary pain to the animal.

Our veterinary technicians are training in performing both of these procedures and can provide a list of animal numbers following identification.
