RFID Rumen Bolus Tag With Applicator

RFID Rumen Bolus Tags are permanent electronic identification devices designed for cattle, sheep, goats, and other ruminant livestock. Encapsulated in durable, biocompatible ceramic, the bolus is orally administered and safely resides in the animal’s rumen, providing lifetime identification and traceability without the risk of loss or damage.

Operating at ISO-compliant frequencies, these RFID bolus tags enable reliable reading with standard livestock RFID scanners, supporting herd management, health monitoring, breeding records, and regulatory compliance. Each bolus comes with a convenient applicator and dedicated RFID reader, making implantation and scanning easy, safe, and efficient. The robust design ensures consistent performance under extreme conditions, including high temperatures, moisture, and the digestive environment. How to Use an RFID Rumen Bolus Tag Applicator

As a professional RFID manufacturer, we offer bulk production and full OEM customization of RFID Rumen Bolus Tags.

RFID Ruminal Bolus for Cattle, Sheep, and Goats

The RFID Ruminal Bolus is a durable electronic identification device designed for cattle, sheep, goats, and other ruminant livestock. Unlike traditional ear tags that can fall off or be damaged, an RFID bolus tag is administered orally and remains permanently in the animal’s rumen, providing secure, lifetime identification.

The bolus is encapsulated in biocompatible ceramic, which protects the RFID chip from stomach acids, pressure, and moisture while ensuring complete safety for animals. It operates at 134.2 kHz LF frequency and complies with ISO 11784 / ISO 11785 standards, making it compatible with most livestock RFID readers used worldwide.

Each bolus contains a unique electronic identification number, enabling reliable livestock tracking throughout the production cycle—from farm management to transportation and slaughterhouse traceability. Because the tag is internal, it offers tamper-proof identification and eliminates the risk of tag loss common with external ear tags.

RFID ruminal boluses are widely used in livestock identification, herd management, veterinary monitoring, food safety traceability, and government animal registration systems.

With a battery-free passive RFID chip, the device can operate for more than 10 years, covering the full lifespan of most livestock.

OEM and ODM customization is available, including chip options, UID encoding, and private label packaging, making the RFID bolus an ideal solution for modern livestock identification systems.
