Equine Performance Test

Ref: 10615
Genetic markers used to indicate the health and determine the physical performance of a horse.

Key advantages
  • Thoroughbred breeding management programs
  • Selection for endurance, strength, stamina, or speed
  • Enhanced athletic performance


Horseracing enthusiasts have long been fascinated with the inheritance of racing ability in thoroughbreds. Yearlings with strong pedigrees are often valued at $1million or more, but quite often do not produce results as expected.

The ability to develop a reliable genetic test that is capable of predicting the type of track-work most suited to a particular animal would provide a reliable method to gain a greater understanding of the potential value of the horse, as well as facilitate a more active and intuitive management of breeding programs.

The invention

It has now been found that polymorphisms in the equine ACE gene are associated with athletic performance. These polymorphisms can be used to create a diagnostic DNA test to identify horses that have better genetic potential that others to perform certain physical tasks.

The discovery of the sequence of the ACE gene, and its relationship to performance will allow for the development of a test to predict the performance as well as monitor the health of the animal.
