HOUŠKOVÁ, Zuzana
The aim of the work was to process facts from Czech and foreign sources about the reproduction of mares. On the basis of the information given in literary sources, monitoring was carried out including monitoring the manifestations and course of estrus, selected characteristics of mares such as BCS, age, current use of individual mares or possible hormonal stimulation. 62 mares in the age range from 3 to 24 years were included in the monitoring. The monitored mares were of various breeds, mares with a sports or hobby career were included, but also mares whose use was primarily for breeding. The aim of this work was to assess the influence of individual selected factors on the subsequent pregnancy of mares and to assess the most suitable combination of characteristics and manifestations of estrus in mares.

BALOUŠKOVÁ, Lidmila
The diploma thesis deals with the availability of cold blood stallions for mating with mares in natural breeding. There are currently three breeds of cold blood horses in the Czech Republic. It is a Noriker horse, a Silesian horse and a Czech-Moravian Belgian horse. In 2020, the total number of horses in the Czech Republic was 92 172, of which 1 352 were Noric horse, 1 365 Silesian horse and 1 971 Czech-Moravian Belgian horse. A total of 132 cold blooded stallions and 532 cold blooded mares were included in the monitoring, which were reproductive active between 2017-2019. In stallions, the age structure, the development of basic body dimensions, the proportion of original genes, the level of performance achieved and the location of the stallion, i.e., the breeding station were monitored. In the case of cold blood mares, the location of the mare was monitored, which was important for determining the distance to the selected stallion. Finally, an economic evaluation was performed
