Abstract
A method and apparatus for detecting standing heat in cattle includes an electronic timer module connected to a membrane switch. The module includes a digital time readout display, as well as audible and visible indicators. A saddle-like sleeve includes a transparent pocket having a sealable opening adapted to receive the timer module and membrane switch therein. The sleeve is adapted to be adhered to the base of the tail of a cow. The membrane switch is adapted to be actuated by the weight of other cows attempting to mount the cow when in heat. The switch actuates the timer, and also actuates intermittent operation of the audible and visible indicators to warn the cattle owner that the cow is in heat, and also to indicate exactly when the cow came into heat.
