Analysis of the jumping performance of young warmblood horses based on the results of breeding competitions in the Czech Republic

Abstract

The aim of the study was to evaluate the performance of warmblood horses in the Czech Republic based on the results of the Criteria of Young Horses (CYH) breeding competitions. In this study, we focused on the evaluation of horses in jumping competitions for mares, stallions and geldings aged 4–6 years. The statistical evaluation is based on the official CYH methodology, which takes into account the different difficulty of competitions for horses of different ages. Data from 2017 to 2021 were used for the evaluation. During this period, 645 horses participated in the competitions with 2691 starts. The statistical analysis evaluated the influence of age, sex, country of origin and breed group on the performance of the horses. Analysis of variance was used for comparison and Scheffe's test was used for subsequent post hoc analysis. Six-year-old horses were rated the highest (22.95 points) despite receiving the highest penalty points (3.29 penalty points). In the sex analysis, the overall rating for stallions was highly significant (P ≤ 0.01) higher than that of geldings and mares. Stallions were the least represented in terms of numbers (22.33 %), but they had the highest number of starts per horse (4.75 starts) and the best mean score (23.32 points). A total of 76.12 % of the horses that participated in the CYH were of Czech breeding, but their scores were statistically highly significant lower (P ≤ 0.01) than those of imported horses, with a difference in mean scores of 0.91 points. In terms of breed, the most numerous breeds were the Czech Warmblood (43.26 %) and then the Czech Sport Horse (17.52 %), but these breeds were below average in the overall evaluation (CZEWB 22.53 points, CSH 22.48 points). The third most represented breed was the Holstein horse, which, on the contrary, achieved the best average results (22.83 points) and the performance of representatives of this breed differed highly significantly (P ≤ 0.01) from most other breeds.
