<p>A membrane switch (24) is connected to an electronic timer module (31) which includes a digital timer display (13), a mounting counter display (16), a flashing clock signal (14) to indicate activation of the module, as well as audible (28) and visible indicators. An oval-shaped sleeve (32) includes a transparent pocket (36) containing the timer module (31) and membrane switch (24), and the sleeve is adapted to be adhered to the base of the tail of a cow. The membrane switch (24) is adapted to be actuated by the weight of other cows attempting to mount the cow when in heat. The switch (24) actuates the timer, the mounting counter, and the flashing clock display (14), and also actuates the audible and visible signals to warn the cattle owner that the cow is in heat, to indicate how long the cow has been in heat, and also how many times the cow has been mounted.</p> |
