Embryo Transfer

Success rates with Embryo Transfer have improved enormously over the last 10 years. It is now a routine gynaecological procedure for competition mares that are unable or unsuitable to carry their own pregnancy. The donor mare is inseminated as normal with frozen, chilled or fresh semen. The embryo is then flushed from her uterus at day 7 after insemination and transferred non-surgically to a recipient mare whose reproductive cycle has been synchronised to that of the donor.

Recipient Mare Hire

B&W Equine Vets has a limited supply of embryo transfer recipients available. The cost of the recipient hire for 18 months (until the foal is weaned) is £1750 + VAT. 

Embryo Freezing

In addition to regular embryo transfer, B&W Stud & Reproduction Services also offers an embryo freezing service.

Embryo freezing or ‘vitrification’ is a method of rapid cryopreservation, resulting in an embryo that can be preserved indefinitely in liquid nitrogen for transferal to a recipient mare at a later stage. Embryo vitrification provides a means of preserving the genetics of a particular mare/stallion combination, for transfer to a recipient when convenient. This can be particularly useful for embryos that are flushed from the donor mare later in the Autumn. These embryos can then be frozen, stored and transferred to recipients early in the spring, resulting in early foals.

Embryo vitrification also removes the need for synchrony of the donor and recipient since the embryo can be frozen until transfer is convenient. In addition, export worldwide of embryos reduces the need for transport of live animals and allows a worldwide market if selling embryos at auction. Please contact the stud team on 01666 880501 if you require further information on embryo vitrification or routine embryo transfer.
