If blood samples are taken less than 60 days after parturition they may test positive, regardless of the current pregnancy status of the animal, due to residual amounts of PAGs from the previous pregnancy. If several females present with this situation (being open following a positive pregnancy test result), it is important to consult with your veterinarian about investigating the underlying problems of pregnancy loss. It is always prudent to retest animals later in pregnancy to confirm their status. Therefore, some females may test as pregnant at 30 days and either return to estrus or fail to give birth.
Most of these losses occur in the first 40 days of pregnancy. These early embryonic deaths often go unnoticed because the conceptus and its membranes are not developed enough for clinical signs of pregnancy to appear. In most species, it is expected that a few animals will lose their pregnancy early on. My animal was positive (pregnant on the test) and she came back in heat or failed to show pregnancy later on? The following are a few facts about how this test is used for pregnancy determination in ruminants.Ħ. One of these tests is the determination of the level of a group of proteins called “Pregnancy Associated Glycoproteins” or “PAGs” in the blood of pregnant animals. In ruminants, research has focused for several years on biochemical and hormonal methods to determine pregnancy status. There are several techniques used for pregnancy diagnosis. Knowing the pregnancy status of an animal is invaluable in making management decisions regarding nutrition and herd health, such as adjusting nutrition to provide for fetal demands, and administration of vaccines to prevent abortion and ensure passive transfer of immunity.Īn ideal pregnancy test is one that is safe and can identify open and pregnant animals with a high degree of accuracy early after mating. Females identified as open can then be rebred or inseminated, thereby providing an economic advantage to the producer. Early identification of open (non-pregnant) females provides a better evaluation of conception rate (often related to male or semen fertility), efficacy of an artificial insemination program, and possible underlying infectious/noninfectious diseases. Determining pregnancy status early on is arguably the most important factor in determining reproductive efficiency. Reproductive efficiency is a major concern for livestock producers, as it can have a significant economic impact on any livestock operation.
