Frekvence příjmu mléčné krmné směsi v průběhu dne a její vliv na růst u telat českého strakatého skotu
Vozihnojová, Dominika
In this diploma thesis analysis of frequency of milk compound intake during the day and its effect on growth in Czech fleckvieh cattle calves was performed in a large-capacity calf shed Kelčice, which belongs to the agricultural cooperative Určice. The monitoring, which lasted 12 months (from March 2022 to March 2023), included the frequency of daily milk compound intake. The calves were weighed on the day of arrival at the reception pavilion and again on the day of daparture to calf nursery at the end of the milk feeding period. During the monitoring, the temperature (°C) and relative humidity (%) in the calf house were measured using the HOBO sensor. Bulls showed greater weight gain (by 0.06 kg) compared to heifers at the same intake of milk replacer (P < 0.01). The greatest growth was recorded in calves that received an average of 7.1 and more liters of milk replacer (MR) per day (P < 0.01). The effect of the number of feeding days was also observed, when calves achieved greater average daily gain during a longer stay in the reception pavilion (P < 0.01). It was observed that temperatures above 20 °C had a negative effect on the calves, which was shown by the average daily gain, which was the smallest at the highest intake of MR. On the contrary, the temperature of 0-5 °C suited the calves the most when it showed the greatest growth.

Vyhodnocení růstové intenzity jalovic na jejich reprodukční a užitkové vlastnosti
Voldánová, Eliška
The main aim of this diploma thesis was to evaluate effects of holstein heifers growth factors and their subsequent reproduction and milk production. The heifers were rear in the same conditions and also their subsequet reproduction and milk production took place in the same stable. No significant (p> 0,05) differences in the weight of heifers weighed a tage of 225, 335, 445 and 580 days were demonstrated for heifers after the sires of the line NXB and for heifers after the sires of the line NEO. Similary, there was no evidence (p> 0,05) of the influence of the order of mother´s lactation on the growth ability of the heifers. From the reproductive indicators of the heifers, the age of embed, the age of calving and the insemination index were monitored. The heifers were most often embed at the age of 13 months. The best age if calving was from the age of 22 to 23 months. Significantly (p <0,05), the best insemination index was found out in heifers from mothers on the 4th and higher lactation (1,17). The best insemination index was shown on the group of heifers which weighed during their time of embed between 400 to 440 kg. The milk production was better after the sires of the line NXB (10556 kg). In terms of grouping by maternal lactation, the best performance was held by heifers after the mother on the 2nd lactation. The content of fat was the similar (about 4 %) in all groups of heifers. The content of protein was similar for all groups of heifers (3,36 %). The best milk production was achieved by heifers calved at the age of 23–24 months. This group had the highest content of fat and proteins. The most favorable milk yield was shown in heifers weighing between 400 to 440 kg at the time of embeding. This group also had the highest fat content, but conversely the lowest protein content.

Evaluation of International Financial Integration on Growth in CEE Countries
Yang, Yang ; Jeřábek, Petr (advisor) ; Li, Yating (referee) ; Čech, František (referee)
The thesis examines the influence of international financial integration on growth in Central and Eastern European economies using a two-way fixed effects model with macroeconomic data for 16 Central and Eastern European countries from 2007 to 2021. The thesis draws several conclusions. First, the ratio of net FDI inflows and outflows to GDP does not present a significant effect on growth. Although the stock data on FDI is similarly not significant for the overall sample regression, the regression of the sample divided into developed and developing economies shows a positive effect of FDI liabilities on economic growth for developed economies and a negative effect of FDI liabilities on economic growth for developing economies. Second, for both the overall sample, developed economies, and developing economies, none of the portfolio investment asset variables are statistically significant, except for portfolio investment assets in developing economies. Third, both portfolio debt and other investment debt negatively affect economic growth in developing economies and the overall sample, while the result is not significant for developed economies.

Modeling the impacts of combined climatic events on the growth, development and yield parameters of field thermophilic vegetables and oilseed rape in the decision support system in the field of agrotechnology transfer - DSSAT
Potopová, Vera ; Muntean, N. ; Chawdhery, M. ; Trifan, T. ; Zehnálek, P. ; Soukup, J. ; Potop, I. ; Zahradníček, Pavel ; Možný, Martin
Modeling the impacts of combined climate events on the growth, development and yield parameters of field thermophilic vegetables and oilseed rape in a decision support system in the field of agrotechnology transfer - DSSAT. This book will introduce you to the latest information technologies and their applications in agriculture, including decision support systems, crop simulation models and other computer tools. It should also help you to solve problems at the regional level on issues related to crop production and other issues related to agriculture, natural resource management and cropping systems and food security, as well as issues related to climate change and variability. This professional book offers users the appropriate supplementary material to enable them to continuously meet the demands of a changing climate. The book is divided into two parts, theoretical and practical. The theoretical part summarizes basic information about simulations of crop production, water and nutrient management, climate risks and environmental sustainability. In the practical part, the procedures for working in the DSSAT program (Decision Support System for Agrotechnology Transfer) are presented.

Analysis of efficiency and risk of investment options in a selected company.
KARAS, Stanislav
The aim of the thesis is to evaluate the current situation of the law office and to select the most appropriate approach to the implementation of acquisitions from the perspective of individual options. The thesis is divided into two parts, theoretical and practical. Within the theoretical part we present important professional information from the investment environment, specifically dealing with approaches to investing, the investment process, financing options, the theory of investment evaluation and other aspects. In the second part, i.e. the practical part, we focus on the actual introduction of the selected law office, the calculation of its financial health, the presentation of individual acquisition options, the calculation of individual financial ratios and we also deal with the substantiation of these results through professional trends within the legal field. All calculations are based on successive calculations of statistics drawing on the data of the selected law office and subsequent adherence to industry trends. In the conclusion of the thesis, recommendations for the implementation of a specific investment opportunity are presented, as well as the results and opinions of the author.

In the process
Volková, Markéta ; Velická, Erika (referee) ; Korbička, Pavel (advisor)
My bachelor's thesis is an object responding to the space that surrounds it. It points out the contradiction between organic and austere form. In my work, I materialize abstract experiences through metonymically selected building elements related to the places in which I have these experiences. As an extraction of elements appearing in the architecture of the Southern Mediterranean, a form of ornament appears in the work, which is understood by a figurative comparison to the experience of travelling on holiday. Another element, representing a figurative experience of returning "to reality", are the lux spheres. Their character is linked to the architecture of Central Europe. I explore the relationship between the different types of buildings, which I then freely develop. My perception of reality enhances the recognition of the new with the already known. I let the objects represent and capture these two opposing perceptions with implications and emphasis on their differences. In this way, I come to find in my work a similarity between geometric austerity, which signifies perfectionism, and the intuitive unfolding of ornament, which inserts the theme of organicity into the object. An important aspect of the thesis is processuality. I understand my work as a border between conceptual and intuitive process.

Induction and potential use of monosex populations of pikeperch (Sander lucioperca) in intensive farming
ŠVEJDA, Pavel
The aim of this study was to induce monosex populations of pikeperch using the method of direct masculinization and direct feminization in order to change sex and evaluate the production parameters and body indices of the treated groups of pikeperch. For direct masculinization, 17 -methyltestosterone was used at a dose of 30 or 50 mg.kg-1 for 30 or 60 days. For direct feminization, 17 -estradiol was used at a dose of 30 mg.kg-1 feed for 30 days. Individuals of pikeperch with TL = 51.52 +- 4.19 mm and W = 1.23 +- 0.26 g, FC = 0.9 +- 0.3 were used for the experiment. In the experiment, direct feminization achieved a sex ratio 98.3 % of females and 1.7 % of males. This is the first record of an almost all-female population induced with 17 -estradiol. The highest level of masculinization of the tested individuals was achieved in the group exposed to 17 -methyltestosterone at a dose of 30 mg.kg-1 feed for 60 days. In this population, 75 % of individuals with male genital tissue were found, of which 21.7 % were individuals whose testicular sperm could be used to produce an all-female population. In groups treated with 17 -methyltestosterone for 60 days, the presence of "neomales" and intersex (hermaphrodite) individuals was observed. The experiment revealed that the use of the hormones 17 -methyltestosterone and 17 -estradiol can temporarily cause growth suppression, particularly during and shortly after exposure of individuals to these hormones. However, it does not have a lethal effect on individuals in the doses we applied. The higher growth rate of pikeperch females was not confirmed in the test. Females treated with 17 -estradiol did not show higher weight gains compared to the control group. A significant difference in the achieved final weight was not observed between both sexes in the control group at the end of the experiment.

Relationship between the age of freshwater pearl mussel and the number of increments in shell section
TOMAN, Jan
The aim of this thesis was to determine the relationship between the age of dead individuals of the freshwater pearl mussel (Margaritifera margaritifera) and the number of incremental lines on the shell section. A total of 124 pearl mussel shells of known age were collected from several Czech, German and Finnish localities. There was a statistically significant difference between the actual age and the age according to the number of incremental lines on shell section. On average, the age determined by increment lines was higher than the actual age by 2.6 years, which is 42 ? 25% (? S.D.). Thus, the increment lines on the section of the pearl mussel shell do not correspond to the annual increments. It was confirmed that increment lines count on the shell surface or estimating age from shell size are less reliable approaches to determine the true age of individuals.
