Stallion inspection: how it works in the Netherlands

What exactly is a stallion inspection?

At a stallion inspection, a studbook assesses whether a stallion has sufficient quality to be used as a breeding stallion. In the Netherlands, studbooks such as the KWPN, the NRPS, and the Friesian Horse Association organise these inspections annually. The aim is to safeguard breeding quality: only stallions that meet the set requirements may register offspring within the studbook. Without approval, a stallion may technically still cover mares, but the foals will then not be eligible for registration as a full studbook animal. This has direct consequences for the value and saleability of the offspring.

The steps of the inspection process

An inspection generally takes place in several phases. Not every stallion makes it through all rounds.

• Pre-selection based on conformation and pedigree (day 1)
• Free jumping or free movement assessment (day 1 or 2)
• Veterinary examination: X-rays, blood tests, and fitness test
• Performance test or stallion trial lasting 50 to 70 days
• Final approval and registration in the breeding stallion register

Conformation and movement: the first filter

The jury assesses conformation according to fixed criteria: correctness of the foundation, build, type, and breed character. This is followed by movement, both in hand and in freedom. For the KWPN showjumper, power and technique over the fence carry significant weight; for a dressage stallion, the jury looks at the quality of the three basic gaits. Each component is scored on a scale from 5 to 10. An average below 7.5 means in most cases that the stallion does not proceed to the next round. Of the stallions entered at the KWPN pre-selection in Den Bosch, an average of around 30 to 40 percent pass the first day.

The veterinary examination in detail

The veterinary component is a hard requirement. X-rays of joints and the spinal column are assessed for osteochondrosis (OC) and other abnormalities. The threshold values differ per studbook. The KWPN uses a points system in which serious abnormalities directly lead to rejection, while less serious abnormalities result in a notation. In addition to X-ray examination, stallions are tested for hereditary conditions relevant to the breed, such as WFFS in warmbloods. A positive DNA result for WFFS carrier status does not automatically lead to rejection, but must be stated in the breeding stallion register.

Stallion trial: performing under pressure

The stallion trial or performance test lasts five to ten weeks and takes place at a centrally designated location, such as Ermelo for the KWPN. Stallions are stabled, trained, and assessed daily on rideability, character, and willingness to work. In addition to the sporting component, behaviour also counts: a stallion that is difficult to handle or shows little cooperation scores lower on the 'rideability' and character components. At the end of the test, owners receive a detailed report with scores for each sub-aspect. This report is valuable for your breeding decisions, and you can easily save it in the horse profile of EquiSight.

Costs and practical preparation

The costs for registration and inspection vary per studbook, but budget for a starting amount of at least 300 to 600 euros for the pre-selection. The stallion trial quickly costs 3,000 to 5,000 euros, including stabling, training, and supervision. Preparation begins months in advance.

• Ensure the studbook passport and DNA pedigree are up to date
• Schedule vaccinations and deworming in good time so the stallion is veterinarily fit
• Train free jumping at least eight weeks before the inspection
• Have an X-ray series taken in advance by a certified veterinarian
• Use the EquiSight calendar to keep track of all inspection dates and deadlines

What does approval mean in practice?

An approved stallion may have offspring registered as full studbook animals, which directly increases the market value of foals. Depending on the approval status — provisional, definitive, or with stars — there are sometimes additional obligations, such as supplying offspring information. In EquiSight you can use EquiCoach to quickly look up which additional requirements your specific studbook sets after approval, and how to manage offspring administration without missing a thing.
