What Cow Ear Tags Do
Cow ear tags give each animal a unique ID — both visual and electronic. The laser-etched number on the surface lets you spot an animal from across the pen. The embedded UHF chip lets you scan the tag with a reader to pull up health records, breeding data, and movement logs without handling the animal.
These tags use a through-hole design. The female tag has a central opening that fits over the male button, locking securely through the ear. This design makes the tag reusable — if a tag gets damaged or you need to reassign an ID, you can remove and replace it without buying a whole new set.
Why These Tags Hold Up
- Reusable through-hole design: Central opening locks over the male button — remove and replace when needed, reducing long-term tag costs
- Long-range UHF reading: Scan cattle at gates, races, or in pens from several meters away — no need to stop each animal
- Laser-etched marking: Numbers, farm names, or custom text permanently burned into the surface — no fading, no smudging
- Large tag face: Big enough for long numbers or farm names to stay readable from a distance
- IP68 sealed body: Fully waterproof and dustproof — survives rain, mud, and pressure washing without chip damage
- TPU construction: Flexible, non-toxic, and skin-safe for multi-year wear on cattle of all ages
- High tensile strength: Pull-tested to stay locked through rubbing, scratching, and daily movement

Applications for Cattle Operations
- Herd identification: Give every cow a unique number that links to health, breeding, and movement records
- Health management: Scan to record treatments, vaccinations, and weight checks without paperwork
- Breeding programs: Track parentage, AI dates, calving intervals, and offspring performance
- Feedlot tracking: Monitor weight gain, pen moves, and feed conversion for groups or individuals
- Movement and traceability: Document transfers between pastures, farms, markets, and processing facilities
- Dairy operations: Connect each cow to milk yield, health treatments, and breeding cycles
- Regulatory compliance: Maintain traceable records that satisfy national livestock identification requirements
How to Apply Cow Ear Tags
- Match the tag with the correct applicator for this tag model.
- Restrain the cow in a chute, headgate, or squeeze.
- Place the female tag on the inside of the ear and the male button on the outside.
- Squeeze the applicator firmly to lock the two parts together through the ear.
- Scan the tag with your UHF reader and record the ID in your herd management system.

Frequently Asked Questions
Q: What are cow ear tags?
A: Cow ear tags are identification tags attached to a cow’s ear. These tags combine a laser-etched visual number with an embedded UHF RFID chip, so you can identify animals by sight or by scanning with a reader.
Q: How do RFID cow ear tags work?
A: Each tag contains a UHF RFID chip that stores a unique digital number. When a UHF reader sends a signal, the tag sends back its ID. Farmers use this to link each animal to health records, breeding data, and movement logs.
Q: How far can these tags be read?
A: With a fixed UHF reader, these tags read up to 8 meters. Handheld readers typically give shorter ranges. Actual distance depends on reader power, antenna setup, and environmental conditions.
Q: Are these tags reusable?
A: Yes. The through-hole design lets you remove and replace the female tag if it gets damaged or if you need to reassign an ID. This reduces replacement costs over the life of your herd.
Q: Are these tags waterproof?
A: Yes. The TPU body is rated IP68 — fully sealed against water and dust. Tags survive rain, mud, and high-pressure washing without damaging the chip or fading the laser etching.
Q: Will the laser-etched numbers fade?
A: No. Laser etching burns the number into the TPU surface. It resists dirt, water, UV exposure, and abrasion better than printed or handwritten markings.
