SBSVS - Mares and Foal

Select Breeders Veterinary Services provides veterinary care, embryo transfer, foaling services, and equine reproductive management of stallions and mares to Cecil County, Maryland and the surrounding Mid-Atlantic Region (MD, DE, NJ, and PA).

In 2013, Select Breeders Services founded a partnership with David Scofield, DVM who is Board Certified in Equine Reproduction.  This was in order to expand our veterinary care and equine management services in Chesapeake City, Maryland.  Through this new division of SBS, operating under the name of SBS Veterinary Services (SBS-VS), Dr. Scofield and the SBS Team are able to provide reproductive management, as well ambulatory care and on-site veterinary services, for our clients.

Laura Serkes - Testimonial Photo"Based on recommendations from my vet, fellow breeders and other performance dressage competitors, I sent my beloved 17 year old, retired FEI dressage mare to SBS Veterinary Services for the delivery of her first foal. After foaling she was then successfully re-bred using frozen semen.  The experience could not have been better. I found the entire team to be a pleasure to work with in every respect. I can't recommend them enough." - Laura Serkes

Embryo Transfer

Embryo Transfer is a proven reproductive technique that places a donor mare’s fertilized embryo into the uterus of a recipient mare that has been correctly synched with the donor mare’s cycle. 

The use of embryo transfer is ideal for:

  • Older mares that cannot carry a foal to term
  • Performance or show mares busy in competition
  • Valuable mares from which multiple pregnancies are desired

At SBS-VS, we can manage and flush your donor mare for an embryo, package and ship the embryo to a recipient herd, utilize your own recipient mare, or place the embryo into one of SBS-VS’s recipient mares. SBS and Unionville Equine Associates (UEA) in Oxford, PA have been collaborating since 2009 to bring ET services to UEA clients. We will continue to provide ancillary support to UEA veterinarians for their clients requiring embryo transfer services.  

With Paul Loomis’ 20 plus years of experience in equine ET and  Dr. Scofield’s training and experience, SBS-VS provides the necessary attention to detail that produces embryo transfer success.
