Abstract
A bolus for use in a ruminant animal's reticulum includes a cavity () configured to receive ruminal fluids present in the stomach. The cavity has walls () of a dielectric material and is encircled by a coil member (), which is configured to subject the ruminal fluids to an electro-magnetic field. A Sensor element () measures the electromag-netic field's influence on the ruminal fluids and thus register an electromagnetic property representative of an acidity level of said fluids. A transmitter () transmits a wireless output signal (SD) reflecting the acidity measure.
