A telemetry system includes a transmitter, which is either placed in the vagina or is implanted in the vulvular or vaginal tissue, and a receiver. The transmitter is capable of measuring physiological parameters which are indicative or predictive of the occurrence of estrus. These parameters may include but are not limited to tissue impedance, temperature and activity of the animal. This provides a pulsed method of measuring impedance of vulvular or vaginal tissue which enhances the marketability of such a device by reducing its size, weight and complexity without sacrificing accuracy or reliability. Data telemetered from this device is preferably collected by a computer and automatically analyzed to provide a report to the farm manager as to which animals are in estrus or are expected to be in estrus at a given time.
