ESTRUS DETECTOR

摘要

PURPOSE: An estrus viewer is provided to use vaginal mucus which is the most significant evidence of estrus of cow as a detection device of estrus and to observe the estrus expression of cow with the high accuracy. CONSTITUTION: An estrus viewer comprises: a transmitter(2) which wirelessly transmits a signal corresponding to the sensing result of the wireless transmitter after the electrical conductivity of the vaginal mucus is sensed by the conductivity detection sensor which is fixed to the cow intravaginal; and a receiver(4) expressing the result corresponding to that signal wirelessly received from the transmitter. The transmitter comprises a wireless transmission unit, electrical conductivity detection sensor, and power circuit.
