Zhodnocení využití a významu plemenného hřebce 2691 Streimur v chovu slezského norického koně
Vraždová, Monika
The aim of this bachelor´s thesis was to evaluate the quality of the offspring of the stallion 2691 Streimur in the breeding of the Silesian Noriker horse. The basic material was the data on the stallion 2691 Streimur, on his offspring and the data of the offspring´s mothers, which were transcribed into Excel format and supplemented with the results of performance tests, body measurements and coloration. Statistical analysis was based on paired t-test between values of mothers and offspring, one-sample t-test of values of mares from offspring and average breeding standard for mares, and finally one-sample t-test between values of stallions from offspring and values of father. In the statistical evaluation of the paired t-test of the values of the mothers with the values of the offspring, a statistically significant difference was found only in the values of the class, when the offspring showed a better evaluation than the mothers. When statistically comparing the average values of the mares from the offspring with the average breeding standard for mares, there was a statistically significant difference in all monitored properties (KVP, KVH, OH and OHOL), the progeny demonstrably showed greater values than in the average breeding standard. In the statistical comparison of the average values of the stallions from the offspring and the values of the stallion 2691 Streimur, there was a statistically significant difference for all, except KVP. The stallion 2691 Streimur, unlike most mothers, improved the class of the offspring.
