Management chovu ovcí plemene suffolk v malochovu
Buchtová, Nikola
The aim of the bachelor thesis is to describe the management of Suffolk sheep breeding in small-scale farming. The thesis describes all the essentials that are associated with sheep breeding on your own farm. It includes, first of all, the issue of reproduction, but also nutrition. The thesis includes practical results of reproductive indicators that were collected on a selected farm in the town of Šumperk from 2016 to 2022. The results concern the evaluation of reproductive indicators of the monitored breeding in ewes, where different success rates in pregnant stallions were recorded in individual years. Attention is also paid to the evaluation of reproductive indicators of the monitored breeding in rams, where a stagnant situation in the success rate of pregnancy from 2016 to 2020 was found. A slight downward trend was then observed. Subsequently, the reproductive indicators of the breed were evaluated, where the numbers of births, lambs reared and the number of losses were compared. Results vary from year to year.

The aim of the bachelor thesis was to evaluate the reproductive and useful properties of dairy cows. The work deals with the comparison of performance parameters and reprodu-ctive properties of milked cattle. The first part summarizes the basic reproductive indica-tors. The next part of the thesis discusses milk and its content of components and its qua-lity, which is followed by the chapter on milk productivity. The production and consump-tion of milk is evaluated in the work both within the Czech Republic and worldwide. In the practical part, the following reproductive indicators were evaluated: Insemination in-terval, service period, insemination index and intermediate period. The level of selected reproductive and utility indicators was analyzed for individual groups of dairy cows ac-cording to the season in one year.
Netradiční druhy masa a jejich využití pro potravinářské účely
Veselá, Romana
This thesis deals with non-traditional meats and their use for food purposes. Specifically, there are 5 species, namely crocodile, ostrich, buffalo, llama and capybara. These meats are suitable as an alternative to commonly consumed meats, but also as a dietary diversification. In some cases, they are healthier, more nutritious, more dietetically appropriate and more appealing in terms of taste. Their disadvantage is their low availability and often high price. In the food industry, they are used in the same way as commercially available meats for the production of canned meat, sausages, semi-finished products, smoked meat products, dried meat and also directly in restaurants for steaks.

The bachelor thesis describes the issue of Doberman breeding in the Czech Republic and partially discusses the standard valid in the United States of America. The specifics of breeding, the history of the breed, including today's use of Dobermans in various segments are described. The bachelor thesis also includes breeding requirements and information on the most common diseases faced by Doberman breeders. It answers questions regarding the occurrence of the two main diseases that Dobermans suffer from and states the degree of influence of these diseases on the quality of life of the affected dogs. This work also researched the average life span of dogs with diagnosed dilated cardiomyopathy. In the thesis the method of questionnaire survey was used to obtain data, as well as the method of data processing and following transformation into graphs and charts. In the practical part of the bachelor's thesis key information on the occurrence of dilated cardiomyopathy and hip dysplasia in the Doberman population was interpreted, along with possible measures that could lead to a reduction in the occurrence of these diseases.

Genetické možnosti šlechtění včely medonosné
Orlova, Sofiia
There was a significant decrease in bees worldwide in the early 21st century. This thesis focused on the study of genetic factors affecting the biodiversity of a population A. mellifera. A lot of genetic markers associated with key features of bees, such as hygiene behaviour and resistance to disease, can be used to select new lines with better characteristics and the potential to maintain and improve bee population. Exploitation of molecular genetic methods, such as SNP detection, has helped to identify genetic variants in some individuals and track their spread. In combination with traditional selection methods, for instance performance-based selection and phenotype analysis, molecular methods allow the selection of individuals with the best genetic characteristics and the improvement of the overall genetic quality of the bee population. Genetic diversity is a crucial factor for the health and survival of bee colonies, it is therefore important for beekeepers to use modern molecular genetic techniques to preserve the best bee qualities.

Janků, Michaela
The diploma thesis is focused on the history and current situation of Thoroughbred breeding, its use in racing and the characteristics of the racing system. The practical part contains an analysis of breeding in the Czech Republic between 2006 and 2010 and subsequent statistical evaluation of the factors such as sex, suffix, period (date) and year of birth, in relation to general handicap (GH) and earnings, in horses born between 2006 and 2010 in flat and steeplechase races. Horses that had shown up on the racetrack at least once were selected for the analysis and we tracked their careers from 2 to 10 years of age. The data were statistically evaluated in the STATISTICA programme. Statistically highly demonstrably lower profits have flat horses of Czech origin CZE (17 464 CZK) compared to FR (70 898 CZK) in 2-year-old horses. Also, the performance of Czech flat horses CZE (53,8 kg) is statistically conslusively lower compared to FR (64,6 kg), GB (65 kg), GER (62,3 kg) and IRE (64,3 kg). 3-year-old flat horses CZE (24 316 CZK) have statistically demonstrably lower profit than horses with suffixes GB (151 767 CZK) and IRE (115 628 CZK). Statistically highly conclusive differences were between horses CZE (52,2 kg) and horses of American origin USA (79,2 kg), GB (70,7 kg), IRE (70,9 kg) and GER (65,8 kg), statistically significant conclusively with Polish horses POL (61,1 kg). In the category of 4-year-old and older flat Czech horses, geldings (56,2 kg) had statistically more performance than mares (53,3 kg) at 4 years of age. The birth year had an impact on the performance of 5, 6 and 7 year-olds, with statistically significant differences in 5 year-old horses between the years 2006 (62,4 kg) and 2010 (50,2 kg), 2007 (59,3 kg) and 2010, 2008 (58,8 kg) and 2010. When evaluating the results of 3-year-old and older Czech obstacle horses, we found a statistically conclusive difference in gender performance between 4-year-old, 5-year-old, 9-year-old and 10-year-old horses. Statistically conclusively differed the gain of mares and geldings in 4 years – mares (59.1 kg), geldings (62.2 kg), then in 5 years – mares (60.7 kg), geldings (63 kg). 9-year-old mares (59.6 kg) had lower performance than geldings (67.7 kg), in 10 years geldings (70.9 kg) again had higher performance than mares (56.2 kg). The effect of sex on profit was statistically different in 9-year-old horses, where the difference between mares (CZK 27,818) and geldings (CZK 107,965) was significant. 10-year-old geldings (CZK 119,285) had statistically more demonstrably higher profit than mares (CZK 5,782).
Analýza délky struků u českého strakatého skotu
Sečkař, Jan
This diploma thesis deals with the analysis of teat length in first-calf heifers of Czech Fleckvieh cattle. The measured teat length is here evaluated and related to other selected indicators of exterior and milk yield in the selected group of first-calf heifers. The work also compares the values of the measured teat lengths with the estimated values of the exterior evaluator from the official evaluation of the exterior of first-calf heifers. In connection with teat length, an analysis of the used bulls and lines in breeding is carried out here. In this experiment were measured 121 first-calf heifers. The average length of hind teats was 3.4 cm and fore teats 4.52 cm. The measured values were statistically significantly different from the official teat length estimate, the teat lengths indicated by the exterior evaluator were on average 0.24 cm higher. It can also be stated that the front teats were on average 1.2 cm longer than the rear teats. The correlation between fore and hind teat length was 0.73. No statistically significant influence of the level of milk yield on the length of the front and back teats was observed. On the other hand, a statistically significant influence of the sire effect (p <0.01) on the length of the front teats was observed. Chest circumference also had a statistically significant (p <0.05) effect on the length of the front and back teats. Dairy cows with a larger chest circumference had longer teats. In conclusion, it can be stated that milk productivity is not related to the length of the teats, the father's influence appears to be essential, so the farmer can solve the problem of short teats in his herd especially by using suitable bulls with regard to the breeding value for teat length.
Vliv rodiny na exteriér a dosažení tělesné dospělosti u plemene Shagya-arab
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.
