Estrus detection device

A method for detecting standing heats in animals comprising the steps of:

• providing a device for detecting standing heats in animals comprising:
• a. at least one fluid storage reservoir, said fluid storage reservoir containing a first indicator fluid and having a first reservoir outlet, said first fluid reservoir collapsing upon compression to propel said first indicator fluid through said first reservoir outlet and substantially resuming its shape upon release of compression to withdraw said indicator fluid at the first reservoir outlet;
• b. at least one timing chamber in fluid communication with said first reservoir outlet, said reservoir outlet sized to fill said timing chamber with said first indicator fluid during a period corresponding to a standing mount for said animal;
• c. wicking means in fluid communication with said timing chamber, said wicking means receiving said first indicator fluid upon compression of said first storage reservoir for a period of time exceeding that required to fill said timing chamber, to record a standing mount;
• d. a second fluid storage reservoir containing a second indicator fluid, said second fluid reservoir having a closed position in which said second reservoir does not communicate with said first reservoir or a timing chamber and an open position in which said second reservoir is emptied into said first reservoir or is in fluid communication with said first reservoir or is in fluid communication with a timing chamber, said second reservoir in said open position placing said second indicator fluid into said timing chamber upon compression of at least one of said first reservoir and said second reservoir and in the even that said compression exceeds said period required to fill said timing chamber, second indicator fluid spills from said timing chamber into wicking means to signal a second standing mount;
• e. animal attachment means affixed to at least one of said first fluid storage reservoir, second fluid storage reservoir, timing chamber, and wicking means for attachment to an animal to allow the detection of at least two standing mounts wherein said device is used for detecting standing heats in cows and other animals.
