In cattle, many twins are born. During the pregnancy, blood is exchanged in about 90 percent of the twins. In male-female twins, this results in male cells being present in the female calf. As a further result, the female has reduced fertility. Polish research has indicated, that also male calves are less fertile.The DNA-test indicates, if a female has male cells in her blood. Female animals with male cells are known as Freemartins.
Test specific information
The test for Freemartinism is based on the presence of male DNA in the blood of a female animal. The analysis is based on a visual interpretation with the possibility that a very small amount of male DNA can not be detected.
The genetic factor is continuously present, and will always be visible.
The Turnaround Time (TAT) depends on various factors, such as the shipment time of your sample to the test location, the test method(s) and whether the tests are performed completely or partially by a Partner Lab or Patent owner.
The TAT of tests performed at our facilities is normally 10 working days after receipt of the sample at the testing laboratory (VHL, VHP or Certagen). For tests performed by a Partner Laboratory (so-called "partner lab test") or patent owner, the TAT is at least 20 working days after receipt of your sample. Because the shipment time to our Partner Labs or patent owner may vary due to factors we cannot influence, the mentioned 20 working days are therefore an estimate.
Sometimes it is necessary to re-run your sample. We call this a retest. In that case, the TAT will of course be extended.
Location of disease or trait
The chromosomal variation is present in the whole body.
For this test samples from all breeds are accepted.
For this DNA test we accept the following materials: Blood EDTA, Blood Heparin. Please contact Dr. Van Haeringen Laboratorium if you wish to submit other material as listed.
The following results are possible:
NO FREEMARTINISM: Male DNA had not been detected
FREEMARTINISM: Male DNA has been detected
Freemartinism is not inherited to the offspring.
