EVALUATION OF WARMBLOOD STALLION PERFORMANCE TESTING SYSTEM
OSTRÝ, Václav
The thesis evaluates the performance testing system of Czech Warmblood stallions. Data acquired from basic stallion preformance test were analysed. Analysed data covered figures of 302 stallions from 9 test stations, taken in years 2007 to 2010. 12 traits of each stallion were analysed. Only basic statistic characteristics were used. Traits were compared by years, testing stations and especially by preferred sirs. The statistic evaluation of traits pointed the best sirs for breeding. Average marks and variability of offspring were taken into acount. Best sirs were Le Patron (x? = 7,84; variability = 2,5 %, Porter (x? = 7,73; variability = 3,0 %) Catango Z (x? = 7,86; variability = 4,4 %) and Przedswit XVI - 12 (x? = 7,85; variabiliy = 4,7 %). Suggestions for improvment of objectivity in performance testing system of Czech Warmblood were given on basis of evaluation component trait/overal score relations. Frequent usage of foreign stallions in Czech Warmblood breeding is common. It is importatnt, for breeders to be familiar with performance testing of foreign breeds. Therefore short description of stallion performence testing across Europe is included in thesis.
