* When the tag is loaded on to the applicator, check the male and female parts of the tag align correctly and make sure calves are securely restrained.
* To decrease the risk of infection at the piercing site, remove any debris from the ear and put the whole tag and the end of the tagger into a container with antiseptic or disinfectant immediately before tagging.
* Wipe the calf's ear with an alcohol swab or spray with antiseptic or disinfectant before the tag is applied.
Placement
* The ideal location is in the middle third of the ear, between the two thickened lines of cartilage (to ensure the structure of the ear is not damaged) and a third to halfway along the ear out from the head.
* Align the tagger. The male tag (with the pin) should enter from the back (outside) of the ear with the female tag facing the front (inside) of the ear.
* Squeeze the tagger quickly but firmly; you should feel a strong click when the ear-tag snaps into place.
* Remove the tagger and ensure the halves are interlocked and the tag is secure and comfortable.
* Watch the calf over the next week for signs of infection or tissue death caused by the tag.
What should I do if the ear gets infected?
* Redness or discharge from the ear indicates an infection. Remove the tag, clean with antiseptic and a topical antibiotic and apply wound powder. Reapply the tag through the same hole once the wound has heeled. If the infection does not heel, seek advice from your veterinarian.
* Tags placed too close to the head will fit too tightly because of the thicker cartilage, and may cause tissue to die or slouch. Tags placed too far towards the tip or bottom of the ear are at risk of being torn out.
* NAIT RFID tags should be placed in the right ear with the female part of the tag facing forward.
* Calves less than 30 days old going directly to a meat processor and which have a "direct to slaughter tag" issued by the processor do not need a NAIT tag.
