Produced in Brazil, this is the system’s identification “trigger”. It contains an enclosed microchip that is connected to a small copper antenna. Together, they make up an inlay.
The technology for animal identification developed at CERTAG makes use of tags that are encapsulated within a ceramic bead called a Bolus. This identification object is initially introduced into the animal’s rumen, via the esophagus. It then makes its way to the reticulum, where it will stay for the whole duration of the animal’s life.

The Bolus CERTAG 7.2 is made from bio-compatible ceramic that was especially designed for this purpose. It emits zero radioactivity and is accepted by the European Community. Within the Bolus CERTAG 7.2, there is a transponder that is able to identify the animal.

The ceramic material produced is the result of a process that involves industrial grinding and drying, and from which a powder is obtained. Later, the powder is pressed and shaped into the desired format. As it goes through the sintering process(42 hours in a furnace, at a temperature of 1,600 º C) and then the vibration stage, all lumps are removed from the material, smoothening its surface and making the ulterior installation in the animal a much easier procedure. Next, a transponder is assembled within the ceramic body and its serial number is tested and documented. The equipment is then packaged along with other units and the box set includes a list of all serial numbers.



The Bolus CERTAG 7.2 was registered and approved by the International Committee for Animal Recording, an international institution for the development of globally accepted standards and norms for the recording and identification of animals. The International Committee aims to make data available to companies, government agencies and the industry.
