Some foreign registries have been more cooperative than others in supplying the data in a useable manner. It is an ongoing and monumental effort, for both the foreign registries and the USTA, to get this information coordinated, validated and computerized in order to have it appear in the official USTA publications. For the purposes of this book, I have chosen to use the European records I have available. This is very valuable information if you are a stallion or broodmare owner, or a yearling buyer. It may list the European owner, but that's all.
Breeders have important decisions to make every year about booking their broodmares.
Some crosses are very obvious and need little thought. But other decisions may be more risky unless the breeder has some idea about what has worked in the past for a particular sire, or with daughters of a certain sire. My purpose here is to point out some of those twists and turns which may not be readily noticed in a cursory review of a sire's produce. This is not a science, and I don't want this book to get bogged down in technical terminology. All I am trying to accomplish is to put the odds more in your favor than they would be if you were merely to guess which sire to breed to which mare.
