Warmblood Fragile Foal Syndrome (WFFS)

Recently, there has been a stir in Europe over a condition in horses that is new to many horse owners and veterinarians; the Warmblood Fragile Foal Syndrome. This hereditary condition has been known in America for some time. Foals can be born prematurely and/or born with abnormalities. The most important abnormalities in newborn foals are skin abnormalities such as a skin that is too elastic, that easily tears and wounds that "just" arise, and hyperextension of joints. Usually the foals are not viable.

Recently, at the initiative of the KWPN, a test was made available in the Netherlands by the Van Haeringen Laboratory.

Frequently asked questions

Published news:

The KWPN has decided to test all active KWPN-approved stallions for WFFS. The breeding season is in full swing and breeders now make the stallion choices for their mares. By publishing the WFFS status of the KWPN-approved stallions we want to inform breeders optimally.

The stallions below were examined by the Dr. Van Haeringen laboratory for the presence of the WFFS gene.​
