Disclosed are methods for determining the pregnancy status of an animal, suspected of being pregnant, using combination tests comprising the analysis of progesterone and ubiquitiin cross-reactive protein (UCRP), which is also known as interferon-stimulated gene product (ISG). The present invention provides for methods of diagnosing pregnancy at very early stages. The benefit of this early diagnosis is that by identifying animals which are not pregnant very shortly after breeding, allows for timely re-breeding thereby minimizing the amount of time the animal is open. Also disclosed are methods for making a breeding decision for an animal. These methods allow a herd manager to make breeding decisions based on the levels of UCRP and progesterone detected in a biological sample take from an animal suspected of being in the early stages of pregnancy. |
