Abstract
An electronic estrus detector that may be affixed to the back of a cow comprises a tapeswitch connected to a counter for storage and display of number of mounts by another cow. When a cow mounts another cow equipped with the estrus detector, the impact of the mounting cow upon the monitored cow closes the tapeswitch and increments the counter, such that the contents of the counter indicate the estrus condition of the monitored cow. In a second embodiment, a modified electronic estrus detector indicates estrus condition based upon satisfaction of a mount-second index. A user programs the estrus detector to shwo when a specified number of mounts, coupled with a specified total time duration of all mounts, has occured.
