Embryo Transfer at Hambleton Equine
Embryo Transfer (ET) us an increasingly popular breeding method for mares that allows them to breed without it affecting their competitive careers
What are the benefits?
- ET has the potential to allow a mare to breed more than one foal each season – maximising their breeding line and without affecting their careers.
- It’s also a fantastic way to produce healthy foals from mares that are unable to maintain a pregnancy themselves.
How embryo transfer works
- Pre-breeding screening: The donor mare is scanned to check her ovaries and reproductive tract and is screened for any contagious diseases that could affect fertility.
- Synchronisation: The donor and recipient mares are scanned to check their cycles are synchronised and to confirm the recipient’s reproductive tract is ready to receive an embryo. We can manipulate the cycles as needed.
- Insemination: The donor mare is inseminated with fresh, chilled or frozen semen.
- Flushing: 6-8 days after ovulation, we gently flush the donor mare’s uterus with sterile solution to recover the embryo. (success rate: up to 70%, depending on the mare and stallion’s fertility).
- Transfer: The embryo is then carefully transferred into the recipient mare. (success rate: 50-70%).
- Ultrasound scans: The recipient mare is scanned 7 days later to confirm transfer success – then as necessary to monitor the progression of the pregnancy.
