Abstract:
A method of determining a physiological state of a ruminant animal by monitoring the core body temperature of the ruminant animal, comprising the steps of:providing a bolus within a stomach of the ruminant animal, said bolus including a temperature sensor and a transmitter;sensing a plurality of temperatures within the stomach using said sensor, each said temperature representing a temperature at a respective discrete point in time over a time periodat least two of said discrete points in time being different points in time relative to each other;transmitting a plurality of air-borne signals to a remote receiver using said transmitter, each said air-borne signal representing at least one of said sensed temperatures;mathematically analyzing a plurality of said temperatures at said discrete points in time over said time period using said remote receiver; anddetermining the physiological state of the ruminant animal using said mathematically analyzed temperatures.
