Bella Vista Equine Reproductive Services offers high quality embryo transfer (ET) services. Recipient mares are provided by Bella Vista Equine. We will synchronize at least two recipient mares per donor mare in case one of the recipients fails to have a normal cycle. The success rate of embryo transfer is dependent upon many individual components. For example: age and fertility status of the donor mare, stallion semen quality, synchronization of both donor and recipients, and handling of the embryo after recovery.  In general, the success rate of ET is around 70 - 75%. Sub-fertile mares may require treatment before entering the program to maximize the success rate. Dr. Elizabeth Martinsen can evaluate your mare on an individual basis to give you a better prediction of results.
