Variability of the linear description of the Noric horses
NĚMCOVÁ, Hana
Noriker horse is native to alpine regions covering the territory of present-day Austria. From there it was extended to the Czech countries through trade routes and import of salt. This thesis deals with the variability of linear evaluation of Noric horses with emphasis on the last 15 years. In this period there were assessed and recorded in studbooks total of 707 Noric horses belonging to 25 recognized lines and 4 lines of imported stallions. For all 22 characters of the linear frequency has been identified individual point values, which corresponded to the normal distribution. Most were represented values around the center point scale. The largest variability of scores has a character type, where the range score is 3 to 9. Between the 5-year periods were found diffe-rences in tenths of the value of the average score from the overall average. Most ba-lanced assessment for each period can be found at the rear pastern character, where the average score in 2005-2009 decreased by 0, 01 than average and the character set of the neck for the period 2010-2014 by 0, 02 higher. The smallest balance of evalu-ation can be observed in the length of the stern, for the period 2000-2004 the average score increased by 0.89 and in the following period lower by 0, 94 than the average. Furthermore, in line with more than 40 individuals, the average scores for in-dividual characters are almost balanced, only Maltum line most sets itself apart, in 6 characters, in the character tap length is the average score by 0.28 higher than average. In lines with less than 40 but more than 20 individuals are significant diffe-rences between the lines due to the small number of evaluated subjects, the most stri-king differences can be observed at line 2934 Hubert Nero IX, which has the most representatives. The highest average score 6.65 amounted line 1542 Nero Diamant VI which is by 1, 02 higher than the average.

Variability of the linear description of the cold-blooded horses in the Czech Republic
RYBNÍČKOVÁ, Karolína
The aim of the study was to compare the cold-blooded breeds of horses bred in the Czech Republic in terms of variability of shaping the exterior and observe differences among the monitored breeds. It was a breed: Czech-Moravian Belgian horse (CMB), Norick (N)and Silesian Norick horse (SN). Whereas these breeds are originated on a different genetic basis and under different conditions, it is assumed that there is difference between them in the formation of physical characteristics. The results showed that the cold-blooded breeds varies highly statistically in these characters: the withers height measured by tape (WHT), circumference of tibia (CT), type, scope, length of neck, deployment of neck, withers length, length of back, loins length, crop length, the slope of the croup, the width of the body scoop , position of the hind limbs, spaciousness of step. For example, a significant difference among breeds was found in WHT, which has the smallest SN and distinguished it from the other two breeds. Furthermore differs CMB, which has the smallest CT, and thus differs it from N and SN. SN has the longest frame of body and the smallest chest circumference of the studied breeds. The highest deploymentof of neck and the shortest neck was detected in CMB in comparison with N and SN. At an average the longest spine was evaluated in SN and the shortest spine was in the CMB. The best spaciousness of step is evaluation in SN. The correlations among selected characters were monitored too. Strong dependence was found between WHT and WHS (withers height measured by stick) in all three breeds.
