Objektivní hodnocení mechaniky pohybu hříbat chladnokrevných koní
KOČVAROVÁ, Ivana
Goal of this study was to assess movement mechanics quality of cold-blooded breed foals (being bred in rearing houses), determine changes in movement mechanics as the breeding advances, and spot possible differences between the cold-blooded breeds in an objective manner.Quality of movement was tracked in two breeding houses in the years 2014 and 2015 and 48 stallion foals aged one, two and three years were included in this study. 24 stallions were of the breed Czech-Moravian Belgian horse, 15 Silesian Noriker and 9 Noriker. All stallions had been weighed in three-month intervals, 13 body measurements were taken and video technology was used to record their movement while being led. Recording was used to determine stride length and height span of right front and right hind leg movement. 354 measurements have been evaluated. Walk characteristics were determined at standardized movement speed of 75m.min-1. Foals bred at an altitude of 650 m were found to have flatter and longer strides than those bred at an altitude of 420 m. The outcome of inter-breed comparison was that Silesian Noriker have the longest stride, while Noriker have the biggest limb movement span. As foals grew older, stride length got slightly longer, while the limb movement span remained without major alterations.

The processing of the cold-blooded stallions catalogue
RAJŠLOVÁ, Jana
The bachelor thesis deals with the processing of the cold-blooded stallions catalogue, which should help to breeders in selecting of a stallion. The main sources for the bachelor thesis were especially catalogues published by breeding organisations in the Czech Republic together with catalogues provided by organisations in other countries. As other sources have also been used catalogues with breeding bulls, especially for a very sophisticated estimates of the breeding values. When comparing the dates provided by various organisations, it was found that in none of Czech catalogues are not the results of the breeding value estimations. In contrast, in the current world it is common to state the breeding values for dressage, jumping, exterior and sometimes also physical dimensions with the sport horses. Mostly are these breeding values completed with a graph. That is why the breeding values for linear features of the exterior description together with the graph adequate to these values were complemented into the design of the cold-blooded stallions catalogue, so that the breeders can compare individual stallions and choose the most suitable one. In conclusion, the established results were evaluated and the methods which follows to improvement of the catalogue in the Czech Republic were suggested. Mainly which information is important to fill into the catalogue and in which period the catalogue should be actualised.
