1. A method for managing the reproductive status of cows comprising:

  • selecting a pressure responsive estrus detection patch from a plurality of color patches wherein each color of patch indicates a particular breeding management status for the cow from a group consisting of;

    a) a first color of patch identifying a cow'"'"'s status as being in the interval between1) parturition and2) first post-partum estrous cycle;

    b) a second color of patch identifying a cow'"'"'s status as being artificially inseminated and in the interval between1) first post partum estrous cycle and2) next estrous cycle;

    c) a third color of patch identifying a cow'"'"'s status as being in the interval between1) having been artificially inseminated in the first post partum estrous cycle and showing a next estrous cycle after the insemination and having received selective management, wherein the selective management choice is from the group consisting of re-insemination and therapeutic treatment; and

    2) the next estrous cycle after treatment or re-insemination;

    d) a fourth color of patch identifying a cow'"'"'s status as being in the interval between1) the first post partum estrous cycle, having received treatment without insemination and2) the next estrous cycle;

    e) a fifth color of patch identifying a cow'"'"'s status as being in the interval between1) an estrous cycle other than first post partum and having been artificially inseminated during a plurality of estrous cycles and2) the next estrous cycle since last breeding;

    f) a sixth color of patch identifying a cow'"'"'s status as being in the interval between1) an estrous cycle without artificial insemination and2) being maintained with a bull for natural mating;

    attaching the selected color of patch to the cow near the dorsal midline between the pelvis and tailhead of the animal; and

    observing and monitoring the cows for release of the indicator substance contained in the patch in response to pressure from mounting.
