New Bridge Embryo Center Procedure
When the donor mare arrives she is checked by our head vet to determine breeding soundness by ultrasound. She is then closely monitored to ensure that she is inseminated at the optimum moment in her cycle.
The resulting embryo is flushed from the donor mare seven to eight days after ovulation. This embryo is recovered via a uterine flushing using a special filter connected "on line" with a silicone catheter placed in the uterus.
 |
Flushing is a simple, non-surgical technique that has been perfected through extensive embryo transfer opertations in Argentina. Industry-wide, the expected embryo recovery rates per flushing run between 70%-80%, however here at New Bridge Embryo Center, we consistenly run over 90% embryo recovery rate per flushing.

 |
The embryo is then taken to our laboratory where it is examined and prepared for transfer. At this point the size of the flushed embryo is typically anywhere from 0.5mm to 1mm. |
|
Once the vets have ascertained that the embryo is viable for transfer, they load it into an insemination pipette and transfer it into the selected recipient mare. We select the recipient mare based on its condition, temperament and, most importantly, how closely synchronized its cycle is to that of the donor mare. An ultrasound examination is conducted on the recipient mare after one week and again after 35 days in order to confirm pregnancy, at which point she is ready to be picked up.
