Santolina has been involved with embryo transfers since the mid 1990’s and we started our own Santolina Embryo Transfer program in 2005.

We offer several ways to accomplish your goals of having a pregnant ET recipient mare either on site or shipping embryo to your embryo receiving location. Embryo Flushing, Transfer and Freezing for Storage is another exciting program at Santolina, especially when dealing with the older, more difficult mares.

Jack refers to them as “his project mares”. We go the distance to have the equipment and facility to provide our best efforts in getting embryos for transplant or freezing.

The challenge can be high with overwhelming rewards, seeing a foal born from extreme efforts.
