Cattle Tags Guide

Load the tag into the universal applicator as follow:

  • Press the metal clamp with the black plastic clip on the lower jaws of the applicator facing inwards (1)
  • Insert tag under the metal clip with the cylindrical locking element facing outwards (2) Do not touch the tip of the pin.
  • Separate the male part of the female part (3) and push male tag firmly onto metal pin (4)

Applicator is now ready to insert the tag


Insert the tag between the two cartilage ribs. Close applicator once, firmly and quickly until the stop and audible click is heard!

Release and withdraw.


Make sure that you or your operator is properly trained and competent in the application of ear tags. Read the Health and Safety Executive’s advice on the handling and housing of cattle (Agriculture Information Sheet 35).

Make sure that you are using the correct applicator for the model of tag you are fitting.
Fit in cool weather (where possible) to minimise infections.

Secure the animal’s head to prevent jerking during tagging.

Apply tags under hygienic conditions. The operator’s hands, the ear, the tag and the applicator should be clean.
Disinfect as necessary using an appropriate solution.

When fitting plastic tags make sure the tags line up correctly on the applicator and will lock to get her when correctly fitted.

In the case of plastic tags ensure that both parts of the tag have the same number.

In the case of plastic tags the female part of the tag should always be on the inside of the ear, this will reduce the chance of the tag snagging or catching on obstructions such as fences, gates and feeding troughs. The male part of the tag should always enter from the back of the ear.

Check the ear after about 10 days for signs of damage or infection. Consult your veterinary surgeon as necessary.

Store unused tags in a clean dry container
