Non-thoroughbred horse breeding

Embryo Transfer

ET has been used in the non-thoroughbred horse breeding industry for many years either to produce progeny from mares that are still competing or playing and from older mares which may be physically or reproductively unable to carry their own foal to term. ET allows superior mares to compete well into their teens, while at the same time producing progeny with their superior genetics.

We offer Embryo Transfer (ET) to client mares between the months of October and February.

The ET process requires that ovulation in the donor mare and recipient mares be synchronized so that the recipient mare ideally ovulates 36-48 hours behind the donor. A mare inseminated with fresh or cooled stallion semen is typically flushed on day 7 after ovulation, whereas a mare inseminated with frozen semen is generally flushed a day later.
