Single-trait and multi-trait prediction of breeding values for show-jumping performance of horses in the Czech Republic

Popis výsledku v původním jazyce

Genetic parameters for show-jumping performance of horses in the Czech Republic were estimated from 483,303 observations of 17,542 horses recorded between 1991 and 2010. The results from events did not have normal distributions. Data were analysed with aleast-squares method (GLM/SAS), and genetic parameters were estimated through a Gibbs sampling method. The statistical model included fixed effects for sex, year of the event, level of difficulty of the event and random effects for rider, permanent environment and an additive genetic effect Six transformations of the data were tested, and the most suitable evaluation was chosen on the basis of lowest residual variance, highest heritability and closest approximation to normal distributions of residualsand breeding values. By these criteria, the best evaluation was accomplished with the shifted Blom-normalised rank for penalty points. For comparison, breeding values were predicted with a single-trait and multi-trait animal model. In the
