thoroughbred breeding and racing

What is KFE?

KEY FACTOR DEFINED

It’s an unusual combination of events in a thoroughbred’s pedigree that gives it a substantial advantage on the race track and in the breeding shed.
 

Without the Key Factor, a thoroughbred, in the past 100 years, has rarely reached an elite status.

How the Key Factor Equine was Discovered

Sometime in 1982, a journey was started with the intent to research and study every mare as far back as complete data would allow. Starting with the letter ‘A’, and using an alphabetical index of mares through the American Produce Records, the arduous task began.

When the process of studying each and every mare began there was no plan or intent on studying anything in particular. It was just a fascination of the wealth of information available through the different thoroughbred publications like Equineline, Equibase, The Bloodhorse, American Produce Records, and any other source of data available.

As time went on, different events, or occurrences, would jump off the page as interesting, or out of the ordinary. Eventually those occurrences were highlighted in different colors, with no rhyme or reason as to why.

What did the Key Factor Equine Show

Whether one uses Classic Winners, Grade 1 Winners, AEI, SSI, or any other statistical means to separate the elite runners, the results are consistent: Mares passing on the Key Factor produced approximately 95% of all the elite runners. This is an incredible percentage. Not only do Key Factor mares have a far greater percentage of superior runners, but they also have a far greater success rate of producing blacktype runners in general.

The research, and its findings, also helped explain why female families will come to prominence and stay relevant with two or three generations of success and then begin to tail off. The Key Factor doesn’t always move forward with each generation and in time, falls off the pedigree and no longer has a positive effect. This pattern is seen over and over again with female families.
