Název v původním jazyce

Estimation of genetic parameters of Thoroughbred racing performance in the Czech Republic

Popis výsledku v původním jazyce

The aim of this study was to estimate the breeding value of English Thoroughbreds in the Czech Republic using racing results from a 22-year period (1980-2001). The data include the performance of two and three-year-old horses which raced in flat races athippodromes in the Czech Republic. The racing results (30 203) were available corresponding to 6 333 horses descending from 762 sires and 2 836 dams. Different criteria were applied in order to analyse the performance: Log of earnings per race, a normalized ranking value, distance of the race when placed, earnings and number of starts for 2, 3, 2+3 year-old horses. After preliminary studies, a year effect or a sex by year effect was finally retained. Variance component estimation using VCE software gave the following values for heritability (+ -standard errors): 0.14 + - 0.01 and 0.16 + - 0.01 for the Log of earnings per race and the ranking value. Repeatability was 0.31 and 0.35, respectively. The maternal environment component was ev
