Mare Management

SBS and our affiliates provide complete breeding management for your broodmare herd, including artificial inseminations with fresh, cooled, and frozen semen, low-dose and deep-horn insemination techniques, reproductive evaluations, diagnostic, and therapeutic treatments. In addition, some of our affiliate locations also offer advanced reproductive techniques like oocyte aspiration and ICSI.


We offer foaling services to limit the anxiety and risk of your mare foaling unpredictably and unattended. Our foaling program provides late term pregnancy monitoring of the mare, specific neonatal care, and a veterinarian attended foaling.

Embryo Transfer

Embryo transfer is an advanced 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.

It is a proven reproductive technique that can be used for older mares that can donate fertilized embryos yet cannot carry a foal to term, performance or show mares in the height of competition, or mares where multiple pregnancies are desired.

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’s recipient mares.
