Abstract

A pressure responsive estrus detector includes a housing having a first and second oppositely disposed side walls. A first interior wall is disposed within the housing and connected to the first side wall to create a first fluid chamber. The first interior wall has a top and bottom and an aperture disposed adjacent to the top. A second interior wall is disposed within the housing and connected to the second side wall to create a second fluid chamber. The second interior side wall is disposed adjacent to the first interior side wall. The second interior side wall has a top and bottom, aligned with the top and bottom of the first interior side wall. The second interior side wall includes an aperture disposed adjacent to the bottom. Fluid is disposed within the housing and flowable between the first and second fluid chambers via the first and second interior wall apertures by pressure applied to either one of said side walls by a mounting animal.

Claims

1. A pressure responsive estrus detector adapted to be secured to a first animal in a position to be contacted by a mounting animal for indicating when the first animal is in heat, the detector comprising:

a housing having first and second oppositely disposed side walls;

a first interior wall disposed within said housing and connected to said first side wall to create a first fluid chamber, said first side wall having a top and a bottom and an aperture disposed adjacent said top;

a second interior wall disposed within said housing and connected to said second side wall to create a second fluid chamber, said second interior wall disposed adjacent to said first interior wall, said second interior wall having a top and bottom aligned with said top and said bottom of said first interior wall, and said second interior wall having an aperture disposed adjacent said bottom; and

fluid disposed within said housing and flowable between said first and said second fluid chambers via said first and said second interior wall apertures by pressure applied to one of said side walls by the mounting animal.

2. The detector of claim 1 wherein the detector is adapted to be reset to a condition prior to mounting of the first animal by the mounting animal whereby the detector can be reused, such that when the detector is secured to the first animal and said second side wall is disposed adjacent to the first animal, fluid is contained in said second chamber prior to the first animal being mounted by the mounting animal and fluid flows into said first chamber upon pressure being applied to said first side wall by the mounting animal;

and

such that the detector is reset by disposing said first side wall adjacent to the first animal, such that fluid contained within said first chamber flows from said first chamber to said second chamber upon pressure being applied to said second side wall by the mounting animal.

3. The detector of claim 1 wherein said side walls include fluid measuring indicia to provide a visual indication of the number of times the first animal has been mounted.
