KFPS Regulations for Offspring Evaluation

1 General information

Within the framework of its breeding program, the Royal Association ‘Het Friesch Paarden-Stamboek’ has regulations for conducting offspring evaluations of studbook stallions. The breeding status of a studbook stallion is determined on the basis of this offspring evaluation. The findings of this offspring evaluation are arrived at after the completion of the judging season and are conducted by the KFPS Inspection Team as based on the collected information. The Inspection Team formulates its recommendations and submits them to the Executive Committee of the KFPS. The Executive Committee arrives at its decisions on the basis of these recommendations. The owner or potential buyer of the studbook stallion is responsible for conducting the offspring evaluation and for the costs involved. In the event that these regulations do not anticipate a specific situation, the Executive Committee of the KFPS shall arrive at any decision in this matter.

2 Offspring evaluation

2.1 General information
There are four fixed times at which offspring evaluation can be used to decide whether a stallion will be rejected from service, whether the offspring evaluation has to be postponed, whether a breeding limitation will be applied, or whether the stallion will be approved for service. If the members of the Inspection Team deem it necessary, they can also submit a proposal to the Executive Committee regarding conducting an offspring judging for a stallion at another time. The four fixed times at which offspring judging is done are:
1 Following the stallion’s second breeding season, conducted on the basis of judging the foals produced during his first year at stud (§ 2.2). Based on this assessment, the stallion can be rejected from service, the offspring evaluation may have to be postponed, or the stallion may be subject to a breeding limitation.
2 Following the stallion’s sixth breeding season, conducted on the basis of judging the offspring produced during his first two years at stud that are three or four years old (§ 2.3). Based on this assessment, the stallion can be rejected from service, the offspring evaluation may have to be postponed, or the stallion may be (provisionally) approved for service.
3 Following the stallion’s eighth breeding season, conducted on the basis of judging a larger number of offspring three years of age and older (§ 2.3). A stallion cannot be rejected from service on the basis of this assessment, but a report drawn up by the KFPS Inspection Team will be issued.
4 Following the stallion’s eleventh breeding season, conducted on the same basis as point 3 but also including the findings relating to his offspring’s capacities in competitive sports (§ 2.3). A stallion cannot be rejected from service on the basis of this assessment, but a report drawn up by the KFPS Inspection Team will be issued.

2.2 Evaluation of foals
The evaluation of the foals will be conducted as based on the following criteria:
1 exterior/development
2 movement
3 markings
4 genetic disorders
The Inspection Team will provide their findings in the form of a foal report made after the stallion’s second breeding season. 

2.3 Evaluation of horses three years old and older
2.3.1 General information
The evaluation of a stallion’s offspring that are three years old and older will be conducted as based on the following criteria:
1 exterior
2 aptitude for competitive sports
3 genetic disorders
4 contribution to reducing inbreeding among Friesian horses
The offspring evaluation consists of:
A. judging the exterior of at least 40 offspring;
B. performance testing (ABFP) conducted on at least 20 offspring.

2.3.2 Offspring’s exterior
To determine the quality of the exterior being passed down by a stallion to his offspring (exterior legacy), at least 40 horses must be inspected. The inspection results of all the stallion’s offspring (stallions, geldings and mares) three years of age or older that have been inspected will be included in this assessment. This also applies to horses that have not officially participated in an inspection but that have participated in performance testing, and, as such, have been assessed (linear scoring) by the Inspection Team. Exterior legacy is indicated in the form of estimated breeding values for both linear and rating exterior characteristics. These breeding values are based on the linear score data as established during the exterior inspection. In breeding value estimates, the quality of the mares serviced by the stallion is also considered. Also included in assessing a stallion’s exterior legacy are the offspring’s uncorrected inspection results.

2.3.3 Offspring’s aptitude for competitive sport
The following data is used to estimate the aptitude for competitive sport of a stallion’s offspring: the ABFP, the IBOP and the scores obtained from participation in competitions organized by the KNHS. One of the ways this estimate is reflected is in a breeding value for aptitude for competitive sport. This breeding value is primarily based on the offspring’s data collected in the ABFP test.

2.3.4 Performance testing of the offspring (ABFP)
The performance testing consists of an ABFP test conducted on at least 20 offspring. The KFPS lists 20 offspring, preferably three-year-olds produced during the stallion’s second year at stud and preferably horses that have been registered for an exterior inspection. The offspring will preferably be selected from among horses stabled in the Netherlands. The selection of the horses will take place three weeks before the exterior inspection. The owner of the selected horse can indicate in advance whether the horse will be made available for the offspring testing. The owner will be responsible for the horse’s vaccinations, shoeing and transport to the testing center.

Preferably, no more than 5 offspring of a stallion will participate in an ABFP test. 

The horses included in the offspring testing will spend 7 weeks, including 2 weeks of preparation, taking the ABFP test.
 
More detailed information is provided in the regulations for the ABFP.

3 Final assessment

The final assessment of the stallions during their fifth and sixth breeding season takes place after the inspection season. A final assessment can be made only after the 20 offspring have completed their performance testing. The findings can consist of the following:
a Approved: Possible once 40 inspected offspring have completed their performance testing. Number of mares that may be serviced: unlimited.
b Rejected: Possible once 40 offspring have been inspected. Number of mares that may be serviced: 0.
c Postponed: An insufficient picture of the characteristics inherited by offspring and the number of inspected offspring fewer than 40. Number of mares that may be serviced: 0.
d Provisionally approved: A sufficient picture of the characteristics inherited by offspring, the number of inspected offspring is fewer than 40, and performance testing is completed. Number of mares that may be serviced: a breeding limit of 180 for the sixth breeding season; thereafter a breeding limit of at least 75 and a maximum of 180. The number of mares that may be serviced depends on the final assessment and the number of inspected offspring. 

During the annual final assessments, all stallions included in one of the categories listed in § 2.1 will be assessed. This means that even stallions that were rejected during a previous stage of offspring evaluation will be assessed again. All stallions with a postponed or provisionally approved status will be involved in the final assessments. 

4 Costs
The costs of offspring evaluation are born in part by the owner of the stallion and in part by the KFPS. The costs to be covered by the owner will be established at the beginning of the year. The costs for vaccinating, shoeing and insuring the offspring for the performance testing are to be paid by the owner of the offspring. The owners of offspring are exempted from any other costs involved in the performance testing.
