bolusThe Datamars bolus is a ceramic capsule containing a passive RFID microchip, which contains the unique, unalterable, fraud-proof identification code specific to each individual animal (UID code). UID codes can be read independently of the position of the microchip inside the animal, whether the animal is stationary or in motion, through any non-conductive material (like the animal’s skin). The bolus is implanted orally and settles in the rumen (second stomach) of the animal with retention rates greater than 99%. Boluses are available in 20 gram, 52 gram or 72 gram sizes.

Suitable for cattle and sheep.
