Abstract
An estrus detection system using a transponder mounted to an animal and including a motion sensor. The motion sensor produces a series of pulses as a function of movement. A counting circuit is energized by the sensor. A storage circuit retains the count together with an identification code unique to the animal. The transponder is interrogated to receive data and such is processed to determine estrus.
