Missing heat cycles in seedstock production can reduce reproduction rates and waste time. To address this need, Allflex, Irving, Texas, is rolling out new remote-monitoring technology for beef producers who use advanced reproductive technology. With the new SenseTime monitoring system, producers reduce the time spent observing cattle for signs of estrus, miss fewer heats and increase the success of their artificial insemination programs. The ear tags sense micromovements associated with key animal behaviors, such as estrus, rumination, grazing, stress or health events, according to Andy Dorn, beef product manager for Allflex in the United States. The tags record animal movements, then transmit the data via field stations to an office computer or smart phone. For more information, see a representative or visit
