Beyond the Basics: The X-Factor - Dosage - Equix Biomechanics - True Nicks

Advancements in technology, combined with the vast wealth of information available via the internet, have proven to be extremely valuable assets in the consideration of Thoroughbred breeding. The great breeders of yesteryear were remarkable, in that their breeding decisions were based upon instincts and principles, and upon the limited number of accurate statistics available to them. Breeders today still adhere to their individual instincts and principles, but also have at their fingertips access to accurate and timely statistics, we well as opportunity to incorporate modern technological advancements into their own breeding schemes. What follows is just a sampling of theories and techniques currently in use. Every theory represents a valid point, but must be considered a singular piece of the overall plan.

The X-Factor

A large heart can enhance the performance of an athlete. The "X-Factor" theory suggests that the large heart is an inherited trait, passed on through female genes only.

Dosage

Frenchman Lt. Col. J. J. Vuillier originated the theory of Dosage in the early 20th century. The theory was modified years later by Italian Dr. Franco Varola. In the early 1980s, Dr. Steven A. Roman began to combine the two theories, and thus formulated the modern Dosage theory.

Equix Biomechanics

Analyses of potential racehorses and breeding stock are based upon physical measurements and angles, and include cardiovascular data collected by ultrasound examination. Very interesting approach.

True Nicks

Initially theorized by pedigree analysts Byron Rogers and Alan Porter of Pedigree Research, the proprietary formula for calculating TrueNicks grades was developed in partnership with Blood-Horse Publications using data made available by The Jockey Club Information Systems.

'It’s a system designed to evaluate sire/broodmare sire crosses. It’s the only system that’s able to take into account - because of the information available from The Jockey Club Information Systems - all foals on a cross. It gives true opportunity for a cross. While it only examines the sire line/broodmare sire line cross, that aspect through studies of more than 100,000 horses has shown to have a tremendous correlation of success." - Alan Porter
