Where are identification tags usually placed on cattle?

• A. Hooves
• B. Nostrils
• C. Ears
• D. Teeth

Answer: (C)

Placing identification tags in the ear is standard because the ear provides a clear, easy-to-read spot that can be accessed with minimal handling. Ear tags (plastic or metal, sometimes with RFID) are designed to be readable from a distance, and the ear’s anatomy allows the tag to be inserted safely and stay secure as the animal moves. Other sites aren’t practical: tags on the nose would be hard to read and could interfere with breathing or feeding color; tagging the teeth isn’t feasible or humane and would be unreadable; hooves are often dirty and hard to inspect, making tag reading unreliable. So the ear is the most convenient and reliable choice for quick visual identification.
