Composition of selected fatty acids in milk fat of cows and goats
KALA, Robert
Milk fat is the recipient of numerous functions. It affects the biological, chemical, sensory and technological properties of milk. The Czech Republic is consumed and processed, especially cows, goats and ewes milk. The aim was to focus on the description of selected fatty acids in milk fat of dairy cows and goats because of their importance to human health and the factors that influence their composition. The results show that the content of short-chain fatty acids was compared to dairy cows higher in goat breeds. It was also found that the proportion of saturated fatty acids was influenced mainly breed and individuality, while the composition of unsaturated fatty acids was affected more nutrition and feeding. The work describes the biological factors such as breed, individuality, parity and stage of lactation, of the external factors described nutrition and feeding. Chapter biological factors mainly deals with the influence of genetics and contains a description of selected candidate genes affecting milk fat and fatty acids.

Performance comparison of selected populations of two breeds of rabitts
POUSTKA, Milan
The aim of the thesis was performance comparison of selected populations of two breeds of rabbits, the Moravian blue (Mm) and the Dutch rabbit (Ho), large and small breed of rabbit in fact. The monitored aspects were the production characters (growth and carcass yield) and reproduction characters (average numbers of birth, number of all births, live born and still-born births and number of weaning rabbits, ability of pregnancy, milkiness). Population of each of the breeds was monitored in a selected base of 68 litters of Moravian blue and 84 litters of Dutch rabbit. Both monitored breeds are recognized by the Czech Breeders Association as bred breeding and club breeding rabbits. Growth was monitored in regular intervals from birth until the end of fattening, i.e. until 8 months of age at Moravian blue a until 6 months of age at Dutch rabbit. The results were compared with the gain in weight published in pattern book of breeds. To evaluate milkiness, each of litters was weighed at 2 and 21 days of age. To compare the reproduction characters the monitored criteria were number of births, total natality and mortality and the number of raised births. The gained values of both breeds were compared and evaluated depending on increment of living mass and the fattening period. Carcass yield was monitored according to the traditional procedure of selected animals of average live weight and after reaching the slaughter age. The results show significantly higher gain in weight throughout the growth period of Dutch rabbit, than required by the pattern book of breeds. Moravian blue showed lower average increase of weight during the first five months of age from standard. The average number of rabbits in litter was 6,3 births at Moravian blue and 6,48 births at Dutch rabbit. On the other hand breeding succest and overall natality gave better results at Moravian blue. It has also been found that the milkiness of Moravian blue was 3985,4 grams in comparison with 2582,2 grams at Dutch rabbit, which is given by the size of breed. The slaughter analysis showed the carcass yield to be 56,1 % at Moravian blue and 62,4 % at Dutch rabbit, which is a value approaching meat breeds but at a lower meat production. The overall summary of the gained results showed greater production of living matter at Moravian blue rabbit providing greater demands for animal housing and feeding base. Its brood provides greater potential for growth and in some aspects better reproduction character. On the other hand, Dutch rabbit reached paradoxically more births in litter and higher carcass yield of undoubtedly better quality meat. Results of this thesis can be beneficial for choosing breed for novice breeders and for existing breeders it can help in their attempts to improve the strengths and eliminate the weaknesses of their breed.

THE INFLUENCE OF THE IMPORT OF FOREIGN STALLIONS ON THE QUALITY OF CZECH WARMBLOOD BREEDING
HAVLOVÁ, Lucie
The aim of this thesis was to prepare an overview of the use of foreign stallions and determine their influence in the Czech warmblood breeding. A representation of stallions of Czech warmblood breed and thein use in breeding was also observed. The results in show jumping were parameters for this evaluation. The data obtained from The summary of the sport horses - Ranking the best sires in ASH (S) by show jumping in the years 2000-2010 were the base material for the thesis. The results showed that the most important breeds in the breeding of Czech warmblood are Thoroughbred, Holsteiner horse, Hanoverian horse and Trakehner horse. Nowadays, the use of Holsteiner and Hanoverian horses increases. The Czech warmblood is becoming the breed used mainly for sports and that´s why the effort of breeders to enhance its sporting performance by the import of breeding material of sporting breeds is growing.

The effect of age on boar semen production and quality of insemination dose
POVONDROVÁ, Tereza
The aim of this thesis was to evaluate the quantitative and qualitative parameters of boar semen for insemination center Radouňka. There were 74 breeding boars of Czech Large White, Czech Landrace and line L48 monitored at the station. Basic quantitative and qualitative parameters of semen were monitored (volume in ml, sperm concentration in 1mm3. motility in % and the percentage of pathological sperms) which were assessed according to breed, age of boar, influence of season and sperm production. The individual parameters of breeding boar?s semen were monitored from January 2009 to December 2011.

Comparison of growth and survival of selected tench breeds in performance test
PRCHAL, Martin
This thesis is focused on comparison of performance traits of growth and survival of selected breeds of the common tench using the pure-blooded animal breeding method. The best way how to compare performance traits of particular breeds is through so-called performance tests. For this thesis following breeds were chosen: Vodňanské -(V), Hlubocké(H), Königswartha (German - N), Mariansko-Lázeňské (ML) and Romanian(R). The Golden tench were chosen as a control breed in order to correct the influence of the environment on the weight achieved. The testing began with selection and stripping preparation of spawners of relevant breeds selected for testing. Own performance test of selected groups proceeded from yolk - sac fry to the age of L2 in ponds with semi-intensive farming. Each tested breed was bred in the first growing period and in winter period together with the control group only. After group marking (the second growing period) by the cryogenic method, all breeds were bred together with triplication. In the first testing period reproductive parameters of spawners and their weight and survival of tested breeds were evaluated, in other period only weight and survival were evaluated. Reproductive parameters in males did not vary statistically in none of the parameters using any statistical method. In females significant differences were proved only between the breeds ?Hluboká? and the control breed. After the second growing period the highest weight was achieved by the Mariánsko-Lázeňské breed (112.9 ? 44.9 g), whose weight was statistically comparable only with German breed (105.4 ? 32.4 g). The survival after this period ranged from 70,4 % (Romanian breed) to 84,1% (Mariánsko-Lázeňské breed) and all breeds had statistically comparable values. The best performance traits after the second year of testing was achieved by the Mariánsko-Lázeňské breed.
