Freemartins (cattle)

LABOKLIN Service ID: 8049

In case of twins of different sexes, about 90% of infertile, externally female calves occur during pregnancy, so-called free martins, due to the transfer of male cells to the female embryo. Already in newborn twins of different sexes, the phenotypically female calves can be examined to see whether they develop as free martins.
