Development and current state of Haflinger breed in the Czech Republic
PATEROVÁ, Šárka
This thesis deals with the current state of Haflinger breeding in the Czech Republic. The number of these horses has steadily risen in the last years and the number of horses ranked among the most important gene lines in the world has risen as well. At the same time the breed found use in other areas than the original agricultural one. The thesis also briefly deals with the world's superpowers in the Haflinger breed, and their significant expansion in the world. The aim of the thesis was to map the current state of stud horses in the Czech Republic. As an overview, an analysis has been made of the current breeding population, comparing the data of the stallions bred in the Czech Republic that are currently enrolled to breed with the mares included in the Main Stud Book. In the conclusion, all the aforementioned differencies are rated and discussed.

Breeding in practice at primary schools in the region Třebíč
KAŇKOVÁ, Jana
This thesis deals with the topic of the breeding at primary schools. By using of questionnaires applied at primary schools in the region Třebíč it was investigated, how is the topic of breeding introduced into the teaching and what is the relationship between students and animals. The thesis also contains proposals for lessons on Breeding.

Repatriation of Atlantic Salmon (Salmo salar) in Czech Republic
ŠRÁMEK, Jiří
This work would summarized the general knowledge about salmon, present information about this field, obtained results of salmon repatriation and possibilities of development this project. Work is further focused in artificial breeding of salmon in incubators and its production for stocking to inland water, the evaluation of factors which influence this activity and possible proposals for new localities and methods to project continuation.

EFFECT OF REARING HEIFERS GRAZING ON MILK YIELD AND FERTILITY
DVOŘÁKOVÁ, Lenka
The agricultural cooperative Opařany 160 pieces were selected for breeding cows anddivided into two groups. Pasture rearing and stable rearing. Which was observed fertility and milk yield. After an overall assessment of the breeding heifers, in 2007 the results of reproduction was worse in pasture system of heifer rearing. By contrast, in the next reporting period in 2008 the grazing system of heifer rearing embody improved results than rearing in stables. After a general evaluation of milk yield, the grazing system of heifer rearing is worse in 2007. In particural the amount of milk in kg and kg of protein. By contrast, in the next reporting period in 2008 the grazing system of heifer rearing reachedimproved results compared stable rearing. And as the number of milked milk in kg, and milk ingredients - % fat, which is in pasture breeding higher in all of KU. The reason of low milk yield results and reproduction charakteristic is especially in poor nutrition and ill-prepared rations, or fed on poor quality components. In the grazing system of rearing the lack of growth in individual animals is due to missing supplementary feed. And for both groups, we should look for causes of poor management and the transfer of young animals to the reproduction and subsequent production should be taken into account the current condition, not age.

Breeding on the primary school
PŘIBYLOVÁ, Petra
This thesis deals with breeding at primary school. In the Framework Education Programme for Elementary Education is included in the educational field Man and the world of work. Pupils are brought into contact with animals in the household and hygiene conditions and farming. This work determines the extent of knowledge that students have in this area and how they relate generally to the animals. On the basis of educational tests and questionnaires which were filled in by eigth grade´s pupils a research was carried out. The results are summarized in this diploma thesis.

The comparison of two breed of sheeps reared in the same area
RAABOVÁ, Alena
The comparison of two breed of sheeps reared in the same area. The aim of the master thesis was the evaluation of the level of the reproductive and the productive traits by the two breeds of sheeps in the area of Novohradské Hory Mts. The examination was conducted from 2006 to 2009. The farm recording and the author´s personal observation were both used for the evaluation. The following traits were recorded: insemination, fertility, intensity, lamb rearing, infertility, mortality. The production traits recorded were the weight of the wool and weight gain in 100 days after the birth. The following results (arithmetic means) were obtained: the rate of insemination by the Valaška breed was 94.3 %, fertility 168.4 %, intensity 158.5 % and the lamb rearing 150.2 %. The rate of infertility was 5.9 % and rate of mortality 5.1 %. The average wool weight was 2.21 kg and the weight gain 175.8 g day-1. By the Merinolandschaf breed, the rate of insemination was 87 %, fertility 134.4 %, intensity 116.1 % and the lamb rearing 101.5 %. The rate of infertility was 13.2 % and rate of mortality 8.8 %. The average wool weight was 4.2 kg and the weight gain 236.9 g day-1. The herd A revealed better results as regards the reproduction traits while the herd B revealed better results concerning the production traits. The significant differences between the examined herd of Valaška sheeps and the Czech population were found in the fertility, intensity and the lamb rearing (T test). By the Merinolandschaf herd, the significant differences from the Czech population were found by the weight gains (T test). The significant differences between the two breeds were found in the fertility, intensity and lamb rearing (T test).

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.
