The Importance of PedigreePedigree Theories

Pedigree is the absolute essence of the Thoroughbred race horse, a breed whose origins lie in its name, being "thoroughly-bred" from the best racing ancestors. While the modern Thoroughbred is not a truely pure descendant of its many Arabian ancestors, its own genetic background has been maintained over 300 years of rigorous selection for superior racing ability. 

"The Thoroughbred exists because its selection has depended, not on experts, technicians, or zoologists, but on a piece of wood: the winning post of the Epsom Derby. If you base your criteria on anything else, you will get something else, not the Thoroughbred." [Federico Tesio]

What was Tesio talking about?  Quite simply, he
meant that the Epsom Derby was the standard and the goal of breeders around the world, and those runners that achieve this highest of standard of classic performance consistently proved to be outstanding breeding stock.  The Thoroughbred is the result of breeding for racing performance and nothing else.  Breeders that concentrate on any other criteria,
especially those that breed strictly to sell an attractive
sale yearling with what appears to be perfect conformation, are not breeding racehorses.

There are many factors involved in breeding
racehorses.  Every few years, someone announces a
new theory or a new line of analysis.  Some are
effective and some are not.  The truth of it is that there
is no one single method that will guarantee success in
this endeavour.  Breeders are encouraged to study the various breeding theories carefully, find the ones that make the most sense to them, and try to engineer
matings that satisfy theory from several different angles.  I've been working on a brief explanation of several of the most well-known theories and selection techniques. This is a work in progress and more articles will be completed as I have the time.
