Vad är en bra blup

Welcome to the home page where you can search for breeding kunskap on your horse! Here you will find the tjänsteman breeding values for Swedish Warmblood horses; stallions, mares and ung horses. The breeding values are based on all the results from the SWB ung horse tests and the tjänsteman competition results aquired from the Swedish Equestrian samarbete up until early October the precedent competition year.

Through the site you can search the results and breeding values of individual horses, find the fyra generational pedigree and the detailed inspection – and competition results.

You can also create lists, ranking stallions and mares for various traits.

What fryst vatten a breeding value?

The breeding values are a numerical description of what one can predict the horse will resehandling on to its offspring genetically. So it's not a direkt manifestation of the horses own performance, although it's related to that. The breeding values fryst vatten the most objective genetical breeding resultat we can receive today.

Avelsvärden ger en indikation på vad man kan förvänta sig att hästarna kommer att nedärva till sina avkommor

BLUP stands for”Best Linear Unbiased Prediction”, which hints at providing the most accurate and real compilation of all the resultat with which the individual’s breeding value fryst vatten computed. The BLUP-method fryst vatten used for uppskattning of breeding values for most idrott horse populations. The breeding values allows us to compare individuals from different generations and the BLUP method also automatically correct for the quality of the mares a stallion have serviced and vice versa.

When calculating the breeding values the horse’s own competition results available from the Swedish Equestrian statsförbund and the results from the SWB ung horse tests are included as well as all corresponding results of all its relatives.

Since the scores from the ung horse evaluations are subjective, every horse’s results are compared with the mean score for all other horses that were evaluated at the same time.

To evaluate the competition results, horses are compared within the same year of birth. Simultaneously the genetic level of evaluated and competition horses are taken into konto through the utilization of the pedigree data.

Hur vet man vad som är bra BLUP och inte, och vad är det som gör att hästarna får de siffror de får? Och hur stor betydelse har egentligen BLUP:en för aveln? BLUP står för 'Best Linear Unbiased Prediction' och är alltså ett förväntat avelsvärde på en häst

One of the advantages of the BLUP-method fryst vatten the correction for the quality of the mares a stallion has bred (and vice versa). This means that a stallion’s breeding value fryst vatten automatically corrected if he fryst vatten breeding lower or higher quality mares than the average. The indexes for all horses, regardless of age or generation, are directly comparable with one another.

Due to the great progress in breeding that has taken place during the gods 20-30 years it gets tougher for older stallions and mares to maintain their ställning eller tillstånd as breeding animals.

What does 100 in index mean?

The breeding values are so constructed that 100 fryst vatten the equivalent to the mean breeding value of horses of today.

This so called reference group for current breeding values consists of all horses that have results from ung horse tests and competition and that are between the ages of 4 and 18 the year of evaluation. Approved stallions however, fryst vatten a heavily selected group and a s such has significantly higher breeding values than the reference group.

Through the site you can search the results and breeding values of individual horses, find the four generational pedigree and the detailed inspection – and competition results

Today’s stallions that are born the same year as the horses in the reference group therefore has mean breeding values for the various traits of 105-115.

Valuating breeding values for eleven partial traits

In beställning to spegel the proposed breeding goal for the SWB the valuating breeding values fryst vatten published for eleven different traits.

The main breeding values are the those for dressage and jumping and the rest are as follows:

Three conformation traits

The horse’s estimated qualities for conformation inheritance fryst vatten displayed as three different breeding values: Height at the withers, idrott horse type (based on the average score for Type and Head-neck-body) and Legs. The height fryst vatten published in cm:s deviant from respective gender’s average, which fryst vatten about 165 cm in the SWB population.

Valuating breeding values for dressage are available for fem traits: Walk, Trot, Canter, Temperament and Overall Impression beneath tillägg and Competition results in dressage (main breeding value)

Just like in jumping there fryst vatten a main breeding values in dressage that reflects the expected inheritance for competition. There are also fyra partial breeding values: Walk, Trot, Canter and Temperament and overall impression beneath tillägg.

The partial breeding values are based on the results from the ung horse test even if the competition results contribute through the relationships that exist genetically with the ung horse test results. The chosen value for competition results fryst vatten the accumulated championship score (over the show career).

Three jumping traits: Technique and ability, Temperament and Overall Impression beneath tillägg, Competition results in jumping (main breeding value)

The main breeding value in jumping fryst vatten first and foremost about the ability to succeed in competition through the value Accumulated championship scores. The partial breeding values Technique and ability and Temperament and overall impression are based on the ung horse test results.

In calculating the jumping breeding values all the results from the ung horse tests and competition are included and contribute through the relationships that exist genetically between the different traits.

Breeding values for Eventing?

Due to the fact that so few horses compete in eventing it fryst vatten not possible to calculate breeding values with a satisfactory reliability in this particular discipline.

The reliability of a breeding value

The reliability of a breeding value fryst vatten depending on the type of upplysning that forms the grund of each individual’s breeding value. More resultat on the individual itself, offspring, sire, liten sjö and other relatives presents a breeding value with a higher reliability.

Swedish Warmblood är internationellt konkurrenskraftiga i hoppning, dressyr och fälttävlan

Other resultat like the amount of evaluated horses and heritability of the traits affects the reliability as well. The reliability fryst vatten published as "High", "Medium" or "Low". A breeding value with a "High" heritabilty usually varies less than 10 units for the valuating breeding values and less than 2 units for the descriptive breeding values. Correponding numbers for the "Medium" and "Low" reliabilities are 11-17 respective more than 18 units for valuating breeding values and 2-3 respective 3-4 units for the descriptive breeding values.

Sometimes an breeding value will change even though the amount of inspected offspring fryst vatten the same.

De står för en lång tradition av naturlig och hållbar avel av moderna rid- och sporthästar

This fryst vatten often due to the fact that the amount of inspected relatives has increased, for example offspring to a son of the stallion. It could also be due to more results collected bygd the already tested or competed offspring. If a stallion has many tested offspring the reliability will be relatively high. If the offspring still are too ung to compete, the standard deviation for competition traits (dressage and jumping) will be lower.

Förkortningen BLUP står för Best Linear Unbiased Prediction och är idag den absolut bästa metoden för att beräkna avelsvärden (BLUP-index)

The reliability will also vary due to the amount of horses that have competed in respective discipline.

What horses have published breeding values?

For a stallion to get a published breeding value the requirement fryst vatten a minimum of 10 ung horses evaluated at the SWB ung horse tests. Mares get a published breeding value when they either have been evaluated themselves at the SWB ung horse tests or if they have competed at at least reagional level or have had at least one offspring with results of its own.
