For some breeds of horses, the most popular choice for marketing frozen semen is to sell by the dose. The mare owner pays in advance for each dose of semen and typically there is no live foal guarantee.This is often the case for imported frozen semen from Warmblood sport horse stallions standing in Europe. However, other breeds use their frozen semen as part of a breeding contract with a life foal guarantee. Much of the Standardbred and Quarter Horse semen we export to Europe and Australia is sold in this manner. At Select Breeders we feel the risk associated with breeding horses, by any means, should be shared by both the stallion and mare owner. Therefore our recommendation has always been to sell frozen semen with a guaranteed contract. We review the pros and cons of both options below and welcome your comments and discussion.
