Predictive height test / withers height (LCORL-related) - Horse

Predictive height testing in horses

This genetic test analyses the LCORL C/T height marker, an important marker for adult withers height in horses. The test is especially useful in Warmblood-type, Thoroughbred and Iberian lines where the relationship between this marker and height is practically informative.

Height is a multifactorial trait: genetics, nutrition, rearing and other growth factors together shape the final adult size. The LCORL marker therefore does not give an exact centimetre value, but it does provide a clear genetic indication for a lower, intermediate or higher height category.

How to read the result

• TT indicates the lower predicted height category.
• CT indicates an intermediate category.
• CC indicates the higher predicted height category.

Practical value of this test

The result helps breeders plan matings more deliberately, estimate young horses earlier and align selection with sport goals, breeding goals or a preferred adult height. In foals and young horses this can be valuable before the mature height is visible.
