Compare studhorse by resuits their progeny in Criteria of young horses [Porovnání plemeníku podle výsledků jejich potomků v kritériích mladých koní]

The objective of the study was to evaluate and compare sires based on results of their offspring in the Criteria of Young Horses. The Criteria of Young Horses are intended for stallions and mares of 4 to 6 years of age. The competitions are announced by the Czech Equestrian Federation in co-operation with breeders associations of the Bohemian warm-blood,Slovakian warm-blood,Kinský horse and Moravian warm-blood breeds. The horses were evaluated in the arena by the assessor and given three marks: for show jumping,agility and readiness of the horse. Data were obtained in co-operation with the Czech Equestrian Federation. Evaluated were the results of the Criteria of Young Horses in show jumping competitions held in 1998-2007. Only sires with 7 and more offspring were assessed. Analysis of variance was carried out followed by tests according to Scheffe. The Excel 2003 and Statistka version 8 were used for processing the database and for statistical processing. Comparisons based on marks given by the assessor in the arena showed that the highest-placed stallion was Acord II and was followed by Catango Z,Calido I and Landos. The offspring of the Hanoverian stallion Walzerkönig were the lowest-placed; the second worst-placed were the offspring of Diktant slatiňanský,a stallion of Czech origin. The differences among these stallions were statistically significant. In comparisons based on marks as the second indicator,the offspring of stallions Acord II,Catango Z and Ascot were the highest-placed and offspring of stallion Diktant slatiňanský were the lowest-placed. The difference between these stallions was statistically significant. Based on the third indicator the offspring of stallions Acord II and Catango Z were the highest-placed. By contrast,the worst were offspring of stallions Duramus II and Duman. The differences between Acord II and Duramus II were statistically significant. According to the resulting total evaluation the highest rating went to offspring of stallion Acord II,followed by Catango Z,Autonom s.v. and Landos. The worst rating went to offspring of stallions Duman,Walzerkönig,Cattaro and Diktant slatiňanský. Comparisons showed that the differences were statistically significant only between Acord II and Diktant slatiňanský.
