摘要：Disclod are methods for determining the pregnancy status of a cow by detecting a pregnancy-associated glycoprotein (PAG) level that compris proteins prent in an acidic protein fraction of day 55 to day 60 bovine placental tissue. The methods may involve using novel polyclonal and monoclonal antibodies that have been generated using the acidic protein fraction as an immunogen. According to the method, the cow is pregnant when the PAG level is prent at an elevated level in a sample obtained from the cow. The invention provides accurate methods of detecting pregnancy at early stages and has the benefit of allowing early post partum detection of pregnancy status with few fal positive results. The antibodies for detecting the PAG level will also be uful in combination with detecting elevated progesterone levels, thus providing an even more effective pregnancy detection method. The benefit of this early pregnancy detection is that identifying cows that are not pregnant very shortly after breeding allows for timely rebreeding and minimizes the amount of time the cow is open. Also disclod are methods for making a breeding decision for a cow. The methods allow a herd manager to make breeding decisions bad on the PAG level and optionally,
progesterone levels, detected in a biological sample taken from a cow suspected of being in the early stages of pregnancy.
