Abstract

A method of determining a physiological state of a ruminant animal monitors the core body temperature of the ruminant animal. A bolus including a temperature sensor and a transmitter is placed within a stomach of the ruminant animal. A plurality of temperatures are sensed within the stomach using the sensor, with each temperature representing a temperature at a respective discrete point in time over a time period. A plurality of air-borne signals are transmitted to a remote receiver using the transmitter, with each air-borne signal representing at least one of the sensed temperatures. The plurality of temperatures are mathematically analyzed at discrete points in time over the time period using the remote receiver. The physiological state of the ruminant animal is determined using the mathematically analyzed temperatures.
