Kinship & Inbreeding Percentage


The Boards of the Friesian horse associations and the breeders together face the challenge and responsibility of improving the quality of the Friesian horse.

Stallion Selection - Breeders should select a stallion whose conformation, movement, sport performance and pedigree will best complement the specific mare for the particular purpose for which the mare is being bred.

Inbreeding - In selecting a stallion, the mare owner has the responsibility to carefully consider the inbreeding coefficient of the resulting foal.


It is not an absolute criterion by itself, but should be considered in conjunction with other factors such as desired conformation, intended use, height, etc.

Inbreeding Coefficients are shown on registration certificates of horses born after 1988. A low inbreeding coefficient indicates that a foal has few common ancestors, thus minimizing the chance of genetic defects. In the Friesian breed, retained placentas also may be associated with high inbreeding coefficients. The FPS recommends inbreeding coefficients below 5 percent if possible. A simple rule of thumb is that in a foal's pedigree, no one name should appear more than once within the first three generations (parents, grandparents, great-grandparents).

Inbreeding Coefficient Forecasts calculate the percentages of inbreeding for foals resulting from the mating of a particular mare with stallions available to the Australian market ie. Breeding permitted stallion or Frozen semen available in Australia.

Members of AFHS/KFPS may obtain an inbreeding forecast for their mare(s) when using approved stallions by logging into MYKFPS   and selecting 'Kinship & Breeding Percentage from the breeding menu.  Assistance when breeding from a permitted or non permitted stallion can be sought from the AFHS board.

Kinship- Kinship percentage is any horses' relationship to the entire Friesian breed.
