My diploma thesis with title Breeding of the Purebred Spanish Horse.Formula clause:ano

The literary overview in the first chapter focuses on the occurrence and discovery of the Przewalski horse. It also deals with their own characteristic. Information about the lifespan of Przewalski horses and individual breeding lines are specified too. Attention was also engaged to the topic of inbreeding and inbreeding depression. The last chapter of a literary overview discusses the current state of the breed. The aim of these theses was to process the data from the general studbook of the Przewalski horses and to evaluate the effect of inbreeding on the length of life of these horses. Data required to statistical evaluation was obtained from the International studbook of Przewalski horse from 2008 and from publicly available internet version of these book. The database contained informations about a sex, date of birth, date of death, lifespan, and the value of the coefficient of inbreeding. Thus obtained data were processed using the program Microsoft Excel 2010 and statistically evaluated in the programs of the UNISTAT 6.5 and SAS 9.1.4. Used to be a basic statistics functions, the Tukey-B test, generalized linear model and Pearson's correlation. Assessing the results of the statistics was detected highly significant effect of sex, year of birth, and the values of the coefficient of inbreeding on the lifespan of Przewalski horses. However, for foals of Przewalski horses, that lived more than two years, has been demonstrated only effect of sex on the lifespan.

The aim of this diploma thesis was to elaborate economic models for estimate the economic indicators and optimization of process for breeding of suckler cows herd in selected farm. The hypotesis of diploma thesis was the assumption that the determination of material and relevance of impact for production indicators of breed will allow to model economic effectiveness of the selected breed farm. Concurrently it can be assumed that is possible to model the influence and impact of market prices for the final profitability of farming, respectively the level of cost per kilogram of live weight gain of animals. Aplications of created models will help to determine the economic turning point and create different models of market situations. The practical part was solved in a company named Ptenínský mlýn, which is located in village Ptenín in district of Plzeň - jih. The company is family character and is involved in an ecological system of agriculture. The company produces cattle for subsequent breeding as well as for fattening and slaughtering. Informations about the company were collected by forms, which were based on 79 asking points. Identified informations were about basic data of the breed and of his expansion in the years. All metods of calculation were created in Program Microsoft Excell 2010. In diploma thesis were determinated the results of the profitability selected breed farm, model s of turning point of cost and revenues, the change of profitability of breed when the parametrs of entrance are changed. On the basis of the calculations was discover negative profitability of breed in the case of absence of subsidies. The margin of profitability confirms this fact. The turning point of sold calves rates actually situation without subsidies. It was discover that for profitability on the based of available documents of company for year 2014 of zero is necessary to sale the calves must to have weight about 1065 kg, which is not possible in real situation. The profit of zero is able to have from to sale of 33 cattles. Without subvences is necessary to reduce of total cost 332 400 CZK, for to have total cost amount 601 600 CZK for to have economy of profitability on level zero. From this situation is clear that subvence allow activity of business and other investments in expansions.

The subject of this masters thesis Family farm as an organic part of the rural space is position of the rural space and agriculture with possibilities for solution of specific problems of the territory. The goals of this thesis are divided into two partial tasks. The first of which is the literature review of contemporary position and happening on the countryside, the position of the family farms in the Czech Republic, the possibilities and conditions of goat breeding and requirements in cultivation. The second part is focused on project design of small family business with focus on dairy goats breeding in the LFA area and production of selected crops. The results of this thesis describe the position of the rural and agriculture in the Czech Republic. The proposal of the family farm as a small business on the countryside represents the development possibility of the village, the attractiveness of the place and total avoidance of depopulation of the village.

The aim of the thesis: Assesment of Parameters of Microclimate in Rabbit Breeding is to make a measurement of microclimate parameters cage housing on a private farm in Velke Nemcice. Part of the work was focused on breeding technologies, namely technology of housing, feeding, watering and removing feces. The highest daily average temperature was recorded in July, when it reached 25.22°C. The lowest daily average temperature was measured in January, when it dropped to 9.31 ° C. In the investigated breeding the most readings of relative humidity reached values between 60-70%. The concentration of carbon dioxide content varied from 0.04 vol.% to 0.009 vol.%. The ammonia concentration in the living zone was about 6-8 ppm. The largest number of live births were recorded in February, when the 11 rabbits born with highly significiant effect (t-test - 0.005). Growth ability can be evaluated in the context of the season highly statistically significant differences in animals up to 5 weeks of age.

The aim of the thesis was to investigate the effect of the protein concentrate on milk quality. The attempt took place on an organic dairy farm with cows of Holstein breed, which was added to the ration a concentrate containing 60 % soybean cake, 20 % sunflower cake and 20 % linseed cake at 1 kg / head / day. The experiment lasted 30 days. Content of fat, protein, lactose, urea, free fatty acids, somatic cell count and the concentration of citric acid was determined in milk samples. Milk production was evaluated from the quantitative parameters. Addition of the concentrate had a positive effect on the fat content (P <0.05) and a decrease in free fatty acids (P <0.05). Production of urea which may be in excessive concentration dangerous for the health of dairy cows, was increased (P <0.05). Concentrate did not affect milk yield, protein content, lactose and somatic cell count. The content of citric acid was increased in the experimental and control groups (P <0.05). The results showed that the addition of protein concentrate can affect certain components of milk, but in case of inappropriate inclusion in the mix, there are health risks associated with excessive excretion of urea.
