Abstract

This invention provides methods and compositions for testing for pregnancy and non-pregnancy in ungulates and non-hoofed ruminates. The tests provided by this invention are useful during a time that coincides with the estrus cycle during which breeding occurs or the first estrus cycle after breeding of a non-pregnant animal. The tests provided by this invention are useful in estrus and ovulation synchronization programs, with pregnancy testing useful at a time allowing for resynchronization of non-pregnant animals within the first estrus cycle. The tests provided by this invention assay for the presence, absence, or level of a selected IFN-τ-induced protein in a sample from a female animal. The tests of this invention are useful for testing cells, blood, plasma, serum, cells, milk, nasal secretions, ocular secretions, vaginal secretions, urine, and saliva samples. The tests provided by this invention are immunoassays. Polyclonal and monoclonal antibodies useful in such tests, as well as methods of making such antibodies and hybridoma cell lines, are provided. Devices for performing such tests, methods of using such devices, and methods of making such devices are provided. Kits containing such devices are also provided. This invention provides a method for determining readiness for breeding. This invention provides a method for resynchronizing breeding with breeding cycle times of one estrus cycle or shorter. This invention also provides a method for breeding by forcing estrus and artificial insemination by appointment.
