Reusable identification transponder inn the form of a bolus for stock management

摘要

The outer cover (10) contains a glass tube (6). This contains a potted transponder whose identification code is read by electromagnetic field. A serial number and identification relative to the code are visible. The housing is closed by a stainless steel weight (8). This ensures that the specific gravity of the bolus is suitable to keep it within the animal's stomach throughout its life.
