Rumen boluses represent the most permanent form of electronic cattle identification. Once administered orally using a specialized applicator, the ceramic or high-density plastic capsule travels to the reticulum (second stomach compartment) where it remains for the animal's lifetime.
Each bolus contains an RFID transponder with a unique identification number following ISO 11784/11785 standards. A specialized reader held near the animal's flank or positioned in handling facilities reads the internal transponder—the same read technology as ear tag systems.
The primary advantage is permanence. Unlike ear tags that can tear out, be removed, or transfer between animals, a properly administered bolus cannot be retrieved without slaughter. This makes boluses valuable for certification programs, export requirements, and situations where identification integrity is paramount.
Boluses are standard identification for many export markets, particularly Europe and South America. Some premium programs require bolus ID for traceability verification. In dairy, they're often used alongside ear tags—the bolus provides permanent backup if tags are lost.
Administration requires training and proper technique. The bolus must be deposited deep enough in the esophagus to ensure passage to the reticulum rather than regurgitation. Applicators are specifically designed for cattle anatomy.
