Influence of the family on the exterior and attainment of physical maturity in the Shagya-arab breed
CERMANOVÁ, Eliška
The aim of the bachelor thesis was to analyse data on the exterior and body dimensions of Shagya-Arab mares at registration in the studbook and subsequently to measure the actual body dimensions of a part of the mare population. The mares were separated by family and the effect of family on exterior, body size and maturity termination was evaluated. For the first part, 332 Czech-bred mares from 10 different families were used and 33 broodmares belonging to 4 families were included in the second part. The enrolment data were: age, final mark, withers stick height, withers strip height, shank circumfe-rence and chest circumference. Actual body measurements were wither stick height, wither tape height, shin circumference, and chest circumference. The results show that the population under study on average meets the breeding objective in all parameters evaluated. The best average score of 7.73 points was found for family 6-CZ. In this family, the highest average stick height (156 cm), the highest average tap height (164.5 cm), the highest average chest circumference (187.82 cm) and the highest average shin circumference (18.90 cm) were still measured. This fa-mily also has the most mares registered in the main studbook (51). According to the results it can be taught that the most powerful (largest) and the most typical mares are from the 6-CZ family. In the studied population of 4 families, a statistically highly significant effect of family was shown only for the age at which growth in height was stopped in mares (measured with a cane in the co-hutch). The result shows that other body dimensions were not statistically significantly influenced by family. From the results it can be concluded that the owner should adapt the age at which he starts working with the horses to the earliness of the individual family. The breeder should then pay attention to the exterior of the parental pair when selecting suitable individuals so that future generations of Shagya-arab horses still meet the breeding objective.

Vliv korektorů na chov moravského teplokrevníka
Sedláčková, Ida
The bachelor’s thesis called “The Influence of Correctors on the Breeding of Moravian Warmblood“ analyses the current population of F1 generation and the situation in the breeding of Moravian Warmblood. In the introduction part I focused on the tree of the breed Moravian Warmblood and its correctors of the English Thoroughbred and Shagya-Arab. For the practical part I used the platform database of 216 horses F1 born from 2004 to 2017 which fulfil the criterion - one of their parents carries 20 and more percent of the original Austrian-Hungarian genes, itself is not an F1 or corrector and the other parent is English Thoroughbred or Shagya-Arab. I divided the horses into several categories which I compared to the real state of the breed Moravian Warmblood. Based on the platform database, it appears clear that the breed correctors are not popular with the breeders. Currently, up to Dec 31, 2017, 261 Moravian Warmblood horses had been listed in the stud book of Moravian Warmblood. Those horses are mentioned that were born in the time when Moravian Warmblood had already been acknowledged as a particular breed, it means just after 2004. Out of this number, just 30 horses are the F1 generation. As a corrector of Moravian Warmblood, much more popular is the English Thoroughbred than the Shagya-Arab. As for the breeding, 7 mares of the English Thoroughbred have been used (14 descendants of F1 generation), 5 studs of the English Thoroughbred (11 descendants of F1 generation), 2 studs of the Shagya-Arab (4 descendants of F1 generation) and just one mare of the Shagya-Arab. Next I found out that just 6 horses of F1 generation have the proven sports performance.
