Abstract: The present invention is directed to devices for detection estrus-state and/or non-pregnancy in mammals and methods for using the same. The device and/or methods may be of particular use in cattle. The devices disclosed include at least a housing of a size, shape, and outer surface quality permitting it to be securely maintained within a mammals vagina. The housing has at least one interior space for installation of instrument(s) for measuring, intra-vaginally, at least on indicia of estrus (heat) or non-pregnancy, converting the resulting measurement into a signal or signals (electronic or otherwise). The device also comprises a signal transmitting means and, optionally, a remote receiving station capable of interpreting the signal(s).

Abstract: Tail-mounted devices and methods for securing an object in an animal's, preferably a cow's, vagina, the device typically comprising a first and second tail anchor or ring, and a tether attached to the first tail anchor. The invention is most suited for and capable of attachment to a housing or object that is inserted into the cow's vagina. The purpose of the disclosed devices and methods is to hold an object resident in the vagina for an extended periods of time, including periods of 14 days or longer.
