Využití samokrmítkových systémů pro okounovité ryby
HOMOLA, Ondřej
This diploma thesis researched the use of self-feeding systems in intensive aquaculture of pikeperch and perch, serving to optimize the production of these fish species. In the experiment with the pikeperch, there was studied the effect of the various types of feeding methods including self-feeders on the production indicators and feeding behavior. In the experiment with the perch, there was studied the influence of the stocking density on the production indicators and feeding behavior using self-feeding.

Principles of nutrition of fallow deer (dama dama)
FRIEDBERGEROVÁ, Eliška
My bachelor thesis deals with literary sources describing the fallow deer (dama dama), their biology, ethology, feeding and the nutrients necessary for this species. It also focuses on the fallow deer farming, its history and requirements, including the legislation. The thesis presents a draft of a feeding concept for farmed fallow deer. This concept is based on an experiment, which has taken place at a private farm Mnich near Kardašova Řečice in collaboration with Výzkumný ústav živočišné výroby Praha Uhříněves. The results of the experiment have become the ground for comparison and the constitution of the most efficient feed intake.

Influence of exothermic sleaves on solidification of aluminium alloys
Zajíček, Roman ; Krutiš, Vladimír (referee) ; Roučka, Jaromír (advisor)
The master’s thesis deals with the influence of the exothermic risers on the solidification of aluminum alloys. The work is divided into three parts. The first theoretical part describes the differences of properties of cast aluminum alloys compared to other based metals, especially iron alloys. It also describes the methodology of designing risers, composition of exothermic mixtures and finally gives an overview on the simulation programs on the market, their application in foundry practice and briefly explains how to define the material in the simulation program ProCAST. The second part describes the experimental measurement of the solidification time of aluminum alloy AlSi7Mg0,3 in the sand form with exothermic riser. The final section describes the simulation of experimental measurements. Further with help of simulation software it is tried to find the general principles that have an influence on feed module rate of exothermic riser.

Drilling Unite
Glembek, Jan ; Budač, Miroslav (referee) ; Špička, Jiří (advisor)
The goal of this work is a design of a hydraulic drilling unit and a manipulator for the PSU 9000 machine. The introduction describes the use of underground mining drilling machines and mentions some of the current solutions. The second part contains the design and calculations of individual components. In the final part, the finite-element method is used for calculation of the bearing parts of the construction.

Thermal insulation and backfilling as a way to save metal and anergy in foundry
Kos, Jan ; Sekanina, Bohumil (referee) ; Kavička, František (advisor)
Types were summarized, principles and thermo-physical properties of thermal insulation and backfilling and their use in the foundry industry to provide directionally solidified castings and then their quality. It summarized the need for numerical simulation of thermal field system casting-form (core)-around the control and prediction of directional solidification. They are some commercial software using different models of solidification. As an example, using one of the models describe the procedure as a pre calculation to decide which of two possible isolation of the riser will be more effective.

Impact of selected factors on laying hens and egg quality.
ZDICHYNEC, Martin
In accordance with the specification of the thesis I developed a methodology target program and I watched it four identical halls, which have different technology housed laying hens. In this thesis are analyzed indicators lay in the selected poultry company in the South Bohemia for the impact of housing hens, their nutrition and feeding. In the selected company enterprise on the one hand technology is used enriched cages EUROVENT - EU Big Dutchman and on the one hand technology aviary housing system used LIBRA with the Italian company of SKA.

Evaluation of cattle rearing on the family farm
VRHEL, Marek
This bachelor thesis is focused on the evaluation of production and reproductive performances of the Jan Vrhel family farm herd in the period 2007 - 2013 and then compared with yearbooks tracking periods with the herds of businesses with established KU (performance testing). The basic economic fundamentals of business profitability were also evaluated , which indicate that the business is sustainable only by contributing grants. Technological methods of rearing calves and heifers were evaluated as well and point to a lower level of breeding and reproductive labor. According to the prescribed diet and analysis of compound feed, it possible to evaluate the status and quality of feeding and nutrition, which is derived from high-quality farm produced feed. Overall evaluation of feeding and nutrition of the cattle in the family business Jan Vrhel, is good. Milk yield was evaluated according to the amount of sold milk and the state of the dairy cows. The evaluation showed that the family business dairy cows are slightly below the average dairy herd with established KU (performance testing)in Czech Republic in the period 2007 -2013. Overall, the Jan Vrhel farm is below the average herd in the Czech Republic with established KU, but due to good investment and improving reproductive and breeding work would be possible to achieve optimal values of all the quality indicators.

Feeding enrichment in selected Felids
PINTOVÁ, Radka
Environmental enrichment and welfare are important elements for animals in captivity. This study starts with general introduction in breeding animals in zoos and environmental enrichment for important taxonomic groups. The practical part is following with a research on effect of food on frequency of stereotypic behavior. The theoretical assumption says that the different time of eating the food leads to different behavior. Long-term observation was done to confirm the theory. Eight animals belonging in three species were observed in time of feeding, eight types of food were given. The behavior at the time of feeding and after was evaluated by ethogram. General trends in time used for feeding were confirmed (the shortest time for chicken and opposite the longest for head of a goat). The evaluation of stereotypic behavior mainly showed the individuality of each animal. However, servals exhibit most of this pattern. The relationship between stereotypes and time of feeding was insignificant. Generally most of the results were statistically insignificant because of low number of repetition in the dataset.
