1. A bovine vaginal probe for detecting estrus which comprises:

  • (a) a relatively non-conductive support means, having a generally cylindrical shape, adapted for insertion into a bovine vaginal tract and contact with the vaginal mucus therein;

    (b) having secured to the surface thereof at least one pair of substantially parallel electrodes aligned parallel to or at an angle of less than 45°

    from the longitudinal axis of said support means, said electrodes being separated from each other by at least 45°

    ;

    (c) said electrodes being electrically connectable to an AC ohm-meter adapted to determine the electrical resistance of vaginal mucus between said electrodes.
