Determination of the risk elements and other elements concentration in animal feed
Křehlíková, Jana ; Juglová, Zuzana (referee) ; Diviš, Pavel (advisor)
This thesis deals with the determination of selected microelements and macroelements and risk elements in dog and cat food. The theoretical part describes the nutrition of dogs and cats and focuses on the safety of the food in the context of contamination with risk elements. Another topic discussed is the chemical analysis of feeds, specifically the determination of nutritionally important substances, beneficial elements, and contaminants. The experimental part deals with the preparation and digestion of feed samples and the subsequent analysis of these samples using ICP-OES and AAS methods. The detected concentrations of the elements of interest in the feeds were compared with the feed standards issued by the Department of Veterinary Medicine and the decree issued by the Ministry of Agriculture. The analysed feeds were found to be deficient in some elements. The content of the risk elements in the feed met the legal limits and did not pose a health risk to the animal. Elements for which the legislation does not provide a maximum permissible limit were present in the feed-in in high concentrations that could already harm the animal's health.

Content of risk elements in food for dogs and cats
Hrabalová, Karolína ; Slavíková, Zuzana (referee) ; Diviš, Pavel (advisor)
This bachelor's thesis deals with the determination of risk elements, namely mercury, arsenic, cadmium and lead in dog and cat food. The concentration of mercury was determined using the AAS technique, and the concentration of arsenic, cadmium and lead was determined by the ICP-MS method after microwave decomposition of the samples using mineral acids. A total of 30 feed samples were analyzed. In most samples, the concentrations of monitored elements were lower than the maximum permissible values given by the EU Commission Regulation, two samples did not meet the requirements of the regulation. The concentration of risk elements in the feed, except for arsenic, did not depend on the type of meat used in the feed. Feeds containing fish meat showed demonstrably higher concentrations of arsenic than feeds with other meats. Due to the relatively low proportion of meat in feed and due to the overall lower concentrations of risk elements in meat, it can be assumed that the vegetable or other component of the feed, or the technology of feed production, is responsible for the increased concentration of risk elements in feed.

Effect of diet on occurrence of gastrointestinal parasites in domestic animals (dogs, cats, hedgehogs, ferrets).
FILCOVÁ, Kristýna
The literature review, which is the part of the diploma thesis, contains a summary of the most widespread methods of pet food. It also contains a summary of gastrointestinal parasites in dogs, cats, hedgehogs and ferrets, and the methods of their diagnostics and therapy. The practical part of my thesis focused on collecting samples of pet excrements in the course of 2021 2023, which were then examined fot the presence of parasites using the standard coprological flotation method. In the course of the above-mentioned years, the questionnares were also provided to the pets owners, which the pet owners filled out. The questionnaire contained questions about the methods of pet food, methods of prevention used against gastrointestinal parasites, possible infection of pets with gastrointestinal parasites and the therapy used, and questions about the knowledge of this issue among pet owners. The number of infections of pets based on methods of pet food, methods of prevention used with individual methods of pet food, occurrence of the endoparasites with the prevention used, the opinion on the effectiveness of the prevention method and the opinion on the possibility to get infected from the infected pet were evaluated as well. The presence of infection with gastrointestinal parasites did not differ in individual categories of pet food. I did not prove that pets fed raw food were infected with parasites from this food. The thesis proves that pet fed heat-treated food, which is not a source of infection, are often infected with parasites. Infection from environment is a source of infection more often than feeding raw food.

Domestic cats (\kur{Felis catus}) as a phenomenon in the conservation biology - their impacts on biodiversity
NOVOTNÁ, Nikola
Lately, a negative impact of ferocious domestic cats on environmental diversity has been ascertained. Using questionnaires, long term observations of cat prey (prey they brought home) and using database data (NDOP, rescue stations and ringing stations) we were finding out about the composition of cat prey throughout the year in the Czech Republic. Based on the questionnaire results, cats bring home 5x more mammals than birds. Out of the results of a long-term cat prey observation it turns out that cat prey consisted of, out of 93% mammals, 6% birds and out of 1% reptiles and insects. In the first observed season (winter), an average of 1 cat brought a 0.02 prey per day, in the second season (summer) 0.21 prey per day, and in the third season (autumn) 0.38 prey per day. Out of the obtained information it turns out that the cat´s impact on environmental diversity is greatest during the third observed season, and is the lowest during the first observed season. The mammal hunted for most frequently was a vole, while the bird hunted for most frequently was a sparrow. Based on our results, birds were carried home most frequently during the summer season, while mammals were carried home most frequently during both the summer and autumn seasons, which was caused by the fact that mostly all kinds of animals were mating during this time. For cats, it is then relatively easy to catch inexperienced young individuals. Out of all the hunted prey, 2.6% consisted of animals being officially protected in the Czech Republic. Thus, the cat´s impact on protected animals in the Czech Republic was proven.

Translation of selected lexical units using machine translation tools.
SRBA, Jaroslav
The present Master thesis deals with the translation of selected lexical units by tool- supporting machine translation. The aim of this study is, on one hand, to identify the limit of the effectiveness of translations of phraseological units, which meaning is associated with diverse parts of the human body. On the other hand, to determine the efficiency of the system as a supporting learning tool for the study of the Spanish language. The first part, the Theoretical Framework, includes a brief introduction of the history of machine translation as well as the selected translators in the investigation. Additionally, this part encloses the theory of phraseology, the corpus that provides the base for the research, the didactical proposal, and the problematical issues of teaching somatic phraseology to students of the Spanish language. The second part, the Methodology, is focused on the translation of selected phraseology by Bing Microsoft Translate, Babylon, My Memory and Google Translate. At the end of the thesis, the statistics of the validity of the translation are presented.

Therapy of epilepsy in dogs and cats
Šenková, Monika ; Vokřál, Ivan (advisor) ; Lecová, Lenka (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Monika Šenková Supervisor: PharmDr. Ivan Vokřál, Ph.D. Title of diploma thesis: Therapy of epilepsy in dogs and cats Epilepsy is a common neurological disorder affecting dogs and cats. This chronic disorder is manifested by recurrent epileptic seizures. The true prevalence of epilepsy in dogs and cats is unknown. It is estimated to be 0,6-0,75 % in general dog population, and 1-2 % in hospitalized dog population. There is no known estimate for general cat population, but it is estimated to be 0,5-3,5 % in hospitalized cat population. Genetic predisposition has been proved in several dog breeds, and in some breeds, it is assumed. Diagnostics of epilepsy could be often difficult, and it reflects only the symptoms described by the pet owner, therefore the close cooperation between the pet owner and the veterinarian is needed. The aims of the treatment are to decrease seizure frequency, duration, severity, and the total number of epileptic seizures that occurs with none or at least minimal adverse effects, to maximize the dog's and owner's quality of life. Currently, there is no guideline for choice of treatment and a final decision should be made on a case-by-case basis. Monotherapy is preferred...
