Updated: Sep 15, 2023


Ear tags for livestock

Livestock ear tags and tattoos play an integral role in animal identification and disease traceability. These two animal identification methods are widely used in communal and commercial farms across the globe. Other methods of livestock identification include branding, ear notching, painting, and the use of microchips.


So, which is better? Livestock ear tags or tattoos? In this article, we’ll examine the pros and cons of livestock ear tagging and tattooing as essential farm management practices. We’ll also detail the steps to follow when tagging or tattooing your livestock. Let’s start with the basics.


What is an Ear Tag?

An ear tag, also known as an animal identification tag is a small piece of metallic or plastic ear attachment meant for identification purposes. The tag bears the animal identification number, letter, or alphanumerical. The animal identification ID number is usually used to indicate sex, sire, problem, date of birth, and other crucial information about the livestock.


Tags are fixed onto the livestock ears using a special pair of pliers also referred to as an applicator. You can buy ear tags and their applicators from farm equipment dealers or online marketplaces.


Federal and state ear tags are supplied and regulated by the U.S. Department of Agriculture through the Animal and Plant Health Inspection Service, APHIS.


Types of Animal Ear Tags

Ear tags differ depending on shape (button-shaped or flag-shaped), size, color (yellow, blue, red), and material (plastic or metallic). Currently, ear tags are classified as electronic or non-electronic.


In a move to enhance animal disease traceability, the U.S. Department of Agriculture is engaging the public to approve Radio Frequency Identification RFID ear tags to be the only legitimate form of cattle identification for interstate movement.


How to Tag Your Livestock

The process of applying ear tags to livestock is quick and simple and you can do it yourself. Indeed, you can follow the manufacturer’s directions and apply the tag appropriately. That said, you should ensure that you choose the appropriate tags for the animal. In addition, ensure that you abide by the county, state, and national animal identification guidelines, especially if the livestock will be moved across states. Below are the steps you should follow when tagging your animals.

  1. Assemble the tools Have in place the instruments needed for applying ear tags. These include ear tags, an applicator, disinfectant, and gloves. Also, ensure the tag have information that you want to capture including sire, sex, date of birth, and so forth.

  2. Catch and restrain the animal You should restrain the animal to avoid getting injured or applying the tag wrongly. Small livestock such as calves, goats, and sheep can be held and tagged by a single person. Be careful with newborn calves because their mothers are overprotective and might gore you. Perhaps, you can use a calf cage to tag newborn calves without getting gored. For bigger animals, use a halter, nose lead, or head gate to restrict head movement.

  3. Determine where to apply the tag Tags shouldn’t be applied too far inside the ear. This site has thicker tissue and might hold the tag tightly resulting in infections such as necrosis. Similarly, tags placed on the extreme exterior part of the ear are likely to be ripped out or snagged. The appropriate location should be between the ribs in the middle one-third of the ear.

  4. Disinfect Always disinfect the applicator and site for the tag by wiping it with 70% alcohol or any other disinfectant before starting to apply the ear tag. This way, you will prevent germs from getting into the pierced site.

  5. Tag application Once you have everything set, it is now time to apply the tag. Note that if you apply the tag correctly, you will avoid issues such as ear infections or the tag falling off. Moreover, a rightly placed tag eases livestock identification. To apply the tag correctly, ensure the parts of the ear tag and applicator are intact and function as required. An ear tag has two parts; the male and female portion. The male part of the ear tag, also known as the stud is the visual panel while the female part is the button. On the other hand, the jaws of the applicator should be correctly aligned to give the best results. And so, you should clamp them to ascertain whether they are aligned properly. With the applicator over the tagging area, place the male portion on the back and the female portion on the front part of the ear. Position everything correctly then press firmly and release the applicator to tag the animal. A sharp sound (clink) will be produced as the two portions of the ear tag join. Now remove the applicator and confirm that the two portions of the tag are interlocked.

  6. Watch the tags After applying the tags, you should keep an eye on the ears of marked animals to identify, prevent or treat problems such as swelling, pain, discharge, or tissue death. Please consider removing the tag to treat the wound if the swelling, discharge, or pain persists.

How to Maintain the Ear Tag Applicator?

The applicator should be properly cleaned before and after use. It should also be sanitized using an antiseptic or a disinfectant. Keep in mind that sharing ear tag applicators among a group of livestock can easily spread bacterial, fungal, and viral diseases.

What Is a Livestock Tattoo?

Livestock tattooing is the practice of placing permanent marks on the skin of farm animals primarily for identification.
