Výskyt ketóz ve vybraném chovu dojených krav v letech 2020-2022
ŠTĚCHOVÁ, Petra
Ketosis is a disorder of energy metabolism characterised by reduced milk yield, inappetence and weight loss. Ketosis also affects milk composition. The aim of this thesis was to evaluate the incidence of ketosis in a selected dairy cow herd. The incidence of ketosis was evaluated in lactating Holstein cows over a period of three years (2020-2022) in the dairy farm in Žákava. Ketosis was detected on the basis of beta-hydroxybutyrate (BHB) content in the blood of the cows using the FreeStyle Optium NEO device. A BHB value of 1.0 mmol/l or higher was considered as an individual affected by ketosis. A total of 1740 dairy cows were included in the study. Ketosis ocurred at a relatively stable level of 20 %. There were fluctuations in the frequency of ketosis across seasons, as well as fluctuations in the average blood BHB content. The effect of the treatment procedure and the effect of prevention on the incidence of ketosis were also investigated. The treatment success rate was 80.41 % for the study period. Treatment with monopropylene glycol and prodigestane was largely successful. Intravenous glucose administration had a slightly lower success rate. Preventive measures had a positive effect on both the frequency of ketosis and the average blood BHB content. In addition, the presence of ketones bodies in milk, the relation of ketone bodies in blood to ketone bodies in milk and the effect of elevated blood BHB on milk composition were determined according to performance monitoring protocols. Both acetone and BHB contents were increased in milk from sick cows. The levels of ketone bodies in milk are positively correlated with the level of BHB in blood. Increased blood BHB content results in a change of content of individual milk components. The highest difference was found in the fat content, an increase of 4,89 %. Further, the citric acid content increased with the BHB content of the blood and the protein, lactose, non-fat dry matter and urea content decrease.

Štítná žláza prasat

Thyroid gland is very important endocrine organ that interferes with a number of processes in the body. Sufficient iodine saturation of animals is essential for optimal production of thyroid hormones. The aim of the bachelor's thesis was to determine iodine supply of slaughter pigs and morphometric parameters of thyroid glands in selected individuals. The study included 27 castrated hybrids of Czech landrace and Pietrain. Iodine content in urine was determined using the Sandell - Kolthoff spectrophotometric method. Thyroid parameters were determined microscopically: length, width, outer and inner area of the follicles and thyrocyte height. The representation of individual size categories of follicles was also determined. The average content of urinary iodine in the observed group was 350.8+-184.3 ug/l, the maximum was 608 ug/l and the minimum was 76 ug/l. Optimally saturated with iodine was 44.44 % of individuals, 11.11 % had a deficiency and 44.44 % an excess of iodine. The average length of the thyroid follicle was 149.3+-64.8 um, width 105.9+-50.6 um, outer area 16810.6+-18030.0 um2, inner area 14318.4+-16985.2 um2 and thyrocyte height 6.2+-2.6 um. In the thyroid glands was 9.4 % small, 62.8 % medium and 27.8 % large follicles. In the selected group of individuals, the impact of different iodine saturation of animals on all monitored thyroid parameters was demonstrated.

Analysis of Banking Products for Entrepreneurs and Firms - differences of the offer provided by Czech banks in comparison with banks abroad
Štěchová, Petra ; Votava, Libor (advisor)
The use of banking products is an integral part of business. For this reason, the theoretical part of the work focuses on the general description. It also highlights the benefits of optimization in this sphere. It also indicates the differences between Czech and European banks, which are most obvious in the bank charges. They discussed the impact of financial crisis, affecting in particular the availability of credit. Practical part of the work focuses on the comparison of products, namely the current accounts of domestic and foreign bank -- ČSOB and Deutsche Bank. The result of this analysis is greater partiality for the establishment of current account at a bank in the Czech Republic. In addition, bank products are analyzed, leading joint-stock company CZ LOKO, which are mentioned experience with their use. Subsequently, the company CZ LOKO recommended a new current account, which is based on the comparison of bids for five lesser-known banks. From this analysis came to establish a new account at a branch of Austrian Oberbank AG, based in the Czech Republic. Finally, carry out a survey on the use of banking products, which demonstrated that all of today's entrepreneurs, to a lesser or greater extent, using bank's services.
