Embryo Transfer

At Oakham Veterinary Hospital we are able to offer a full embryo transfer service

Embryo Transfer

Embryo Transfer is a relatively new breeding technology that is gaining popularity as it offers owners the chance to breed from their mares without interrupting their competitive schedule. ET can also be appropriate for mares that are incapable of carrying their own pregnancy or where the owner is unwilling to take the inherent risks of putting their valuable mare in foal.

In very basic terms embryo transfer involves flushing a fertilised embryo from the donor mare at 7 days post insemination and then transfering into a well synchronised recipient mare.

At Oakham Veterinary Hospital we are able to offer a full embryo transfer service - if you are able to provide your own recipients (at least 2 are required) we are able to perform the entire process on site.

However, if you are unable to provide the required recipient mares we have a solutuon via our transported embryo service. This involves shipping the embryo to be implanted in a recipient mare that has been synchronised to be at the same point in the oestrus cycle as the donor mare. For this service we use Twemlows Hall Stud Farm who run a large, well maintained recipient herd. The donor mare would be prepared and inseminated here at Oakham, then after 7 days she is then flushed, the embryo is collected, packaged and chilled then dispatched via courier to be transferred into the recipient within a few hours.

Please contact Matt or Alex at the hospital for more detailed advise about our embryo transfer program and related charges.
