We will be taking a winter break from July 6-19 (NSW school hols). You can still place orders now, and also while we are on break. If we receive but don't finish testing your samples they will be first in line when we re-open.

Splashed white 3/deafness (SW3)

Summary

The splashed white 3 (SW3) gene causes white markings. They can range from minor facial markings and socks to the white face, blue eyes, white legs and white belly of a typical boldly marked splash horse. Most SW3 horses have fairly extensive markings. Like all splashed white horses, it is possible for SW3 horses to be deaf.

The SW3 version of splashed white has so far only been found in pure and part-bred Paints descended from TD Kid, a Paint stallion born in 2001 in the USA.

At this point there are no known instances of horses carrying two copies of SW3.
