Selection and Training
A C:T horse has a mixture of speed and stamina and is the most versatile in terms of distance. A C:T horse can
perform well as a two-year-old, but is best suited to races between 7 - 12 f (1400 - 2400 m). Only C:T horses are
likely to win both one mile (1600 m) and one mile and a half (2400 m) Group races. A C:T stallion is more likely
to produce winning two-year-olds if compatible mares are used. The progeny of a C:T mare over her life-span will
be C:C (25%), C:T (50%) or T:T (25%), and these proportions can shift towards more speed (C:C and C:T) if a C:C
stallion is used or towards more stamina (C:T and T:T) if a T:T stallion is used.

Mid-distance Panel is most critical for C:T horses. C:T Class 2 (Middistance) is 1.64 times more likely than average to win a Black-Type
race in its lifetime.
CT Class 2 horse with SP panel score 2 has a 18% higher expected total
earnings than CT Class 2 horse with SP panel score 4

Note: Sprint and Stamina panels have no observed effect on distance for

SGT
Speed Gene Test
Best race distance and precocity potential in Thoroughbred racehorses can be
predicted by the DNA analysis of the MSTN gene, a major regulator of muscle mass
development and muscle fibre type.
Genetic Type
In the MSTN gene, a position in the DNA code contains either the DNA variant C
or the DNA variant T. Each individual has two copies of the gene—one inherited
from the dam, one from the sire, so there are three possible genetic combinations:
C:C, C:T or T:T.

Elite Performance Test
Equinome has developed large panels of DNA variants that can now be used to
distinguish between elite performers and poor performers within each distance
category, which is first determined for a particular horse using the Equinome
Speed Gene Test. Approximately 80 genetic variants are tested for each panel.
The combination of advantageous DNA variants determines whether a horse
is genetically Class 1, 2, 3, or 4 on each panel, with Class 1 having the highest
potential and Class 4 the lowest potential for elite race performance
(Black Type race win.

PHT
Projected Height Test
Mature height at withers can be predicted within 2.54cm (1 inch) with a 70%
success rate from birth, based on DNA analysis of the LCORL/NCAPG gene region
and the sex of the horse.
Genetic Type
Physical Type
At the LCORL/NCAPG gene region, a position in the DNA code contains either the
DNA variant G or the DNA variant A. Each individual has two copies of the gene—
one inherited from the dam, one from the sire, so there are three possible genetic
combinations: G:G, G:A or A:A.

Speed Gene Test
The potential outcomes from any breeding combination can be predicted if the
genetic type of the mare and stallion are known, as shown in this table. This test
can be used with current selection tools to shortlist mares and stallions most likely
to produce the desired result.
Projected Height Test
This information can be used by breeders to produce horses of a desired height
more consistently. If the stallion and mare genetic types are known, the potential
outcomes can be predicted as per the table below.
