Warmblood Fragile Foal Syndrome (WFFS)

The Warmblood Fragile Foal Syndrome is a hereditary disorder that has been recognized in the United States for several years. A foal with WFFS can be aborted, be born prematurely and/or be born with abnormalities. The most important abnormalities in the newborn foal are: skin abnormalities (such as too elastic skin that tears easily, wounds that 'just' occur) and hyperextension of joints. Usually the animals will die within 1-2 weeks of birth or they need to be euthanized.

In the context of the Warmblood Fragile Foal Syndrome (WFFS) it is advisable to test broodmares so that you know whether your mare is a carrier. Research into carrier status is very simple at the Van Haeringen Laboratory.

WFFS-status KWPN-approved stallions

The KWPN has decided to test all active KWPN-approved stallions for WFFS. By publishing the WFFS status in the KWPN Database of the KWPN-approved stallions we want to inform breeders optimally.
