Degradace krajiny a její vnímání pastevci na Sokotře
Jurczková, Nikola
Overgrazing is one of the main causes of landscape degradation in Socotra. This bachelor is focused on research on local herders and their perceptions of landscape degradation on the island. Also, the willingness of herders to participate in environmental protection is examined. The research was conducted through a questionnaire survey during the period 9.10. –9.11.2021. The results show that the pressure on tree vegetation has increased due to changes in traditional farming practices. The research also confirmed that herders are aware of landscape degradation, even perceiving a link between land degradation and overgrazing. Herders are aware of the negative impacts on their livelihoods as a result of landscape degradation but are unaware of the future consequences and threats to the existence of forests. Many of them are willing to voluntarily contribute to environmental protection. Herders are open to development cooperation, participation in landscape management or education through seminars. They are also willing to reduce grazing in the forest or reduce the number of their livestock in order to protect the forest, but many of them only with certain compensations. Local people depend on their livestock as they are the main source of livelihood for the local population and other forms of management are very limited due to climatic conditions. The research conducted helped to understand how herders perceive landscape degradation and to what extent they are willing to cooperate in nature conservation.

Specifika reprodukce koní
Maňasová, Michaela
The bachelor thesis deals with the issue of specifics in the breeding and reproduction of horses. The theoretical part firstly describes genital organs of mares as well as stallions and the differences from other species of livestock. Next the thesis characterizes mare’s sexual cycle and methods of horse reproduction regarding their advantages and disadvantages. The next section of the theoretical part gives attention to specifics of the whole reproductive cycle and its comparison to other livestock. And the final part of the theoretical part provides the options for affecting the mare’s sexual cycle. The practical part covers the evaluation of reproductive traits of horse breeding in Hřebčín Vlachovice between 2015 – 2018 period. During these reproduction seasons, there were two stallions – Age of Jape and Ray of Light. It is looked on indicators as the amount of covered and pregnant broodmares, fertility of stallions, effectivity of mare’s getting pregnant or mare’s ability to get pregnant after having a foal. As the last but not least factor watched in the thesis is using hormonal products at mares.

Methodology for use of technological waters on agricultural land (3rd ed.)
Mühlbachová, Gabriela ; Svoboda, Pavel ; Klír, Jan ; Vegricht, Jiří
The production of technological waters from stables is evaluated in the methodology for the use of technological waters in agriculture. The corresponding legislation amended in 2021 is described. Attention is focused on technological waters from livestock breeding and simple processing of plant products. The production of technological waters is evaluated from the point of view of individual operations in which the technological waters are produces, particularly in milking and cooling equipment. THe characteristics of technological waters, particuarly the nutrient contents and potential risks of their use on the agricultural land are also evaluated in the methodology. the influence of tehcnological eaters on the growth of plants and microbial biomass content and activity in the soil was experimentally verified. The methodology contains the recommendation for the application of technological waters on the agricultural land.

Traditional and nontraditional farm animals and their importance to human life
Procházka, Jiří ; Hanel, Lubomír (advisor) ; Řezníček, Jan (referee)
The Abstract The main purpose of my thesis is to make summary of conventional and unconventional livestock and their importace to man. My thesis brings in survey of the most significant kinds of breeds and their economic exploitation. A separate section is devoted to Czech breeding of essential kinds of livestock in reference to their conditions and animal production capacity. Out of unconventional groups of livestock, the attention is devoted to birds from out superorder runners. The importace of meat in man's nutrition is widely discussed. As a part of thesis, a public inquiry was compiled and analysed. It was interpreted on samples of students and workers of educational institutions. The inquiry discovers the influence of respondents'demografic field and other circumstances upon meat consummation. As a suplement to the biology education at primary and secondary schools, a CD- ROM is made containing questions to systematic zoology of birds from among superorder runners. Key words: domestication, livestock, runners, meat, inquiry

Methods of sperm selection for human and veterinary assisted reproduction
Pavlová, Hana ; Komrsková, Kateřina (advisor) ; Koubek, Pavel (referee)
Sperm selection is an important process influencing the progress of fertilization and the quality of resulting embryos. Competent sperm cells can be isolated from an ejaculate sample according to different criteria. Standard methods allow for sperm selection based on conventional parameters, particularly motility and density. Using advanced methods, sperm cells are selected according to molecular aspects including for instance membrane charge, presence of specific receptors, molecules indicating ongoing apoptosis, and others. The latter procedures are widely used particularly in human practice. Their use is uneconomical in veterinary practice and standard methods including the centrifugation step in the procedure are primarily used to select the sperm of livestock. Sperm cells of livestock are also often selected according to whether it carries the X or Y chromosome. Thus, the sex of the offspring can be effectively determined in order to increase the efficiency of the production of animal products. This thesis presents the most frequently used methods of sperm selection for the purpose of oocyte fertilization in human and veterinary sectors of assisted reproduction and discusses their impact on the parameters and fertilization potential of isolated cells.

Legal Protection of Animals, Focusing on Livestock and Furbearers
Čapková, Petra ; Derlich, Stanislav (advisor) ; Stejskal, Vojtěch (referee)
Legal Protection of Animals, Focusing on Livestock and Furbearers The diploma thesis titled "Legal Protection of Animals, Focusing on Livestock and Furbearers" provides a comprehensive overview of current framework of the legal protection of animals in the Czech Republic. The thesis is divided into seven chapters and several sub-chapters. The initial chapters present information on the historical tendencies and philosophical bases of animal protection, as well as on the development of the perceiving of animals as subjects of law, which has over several centuries formed into our contemporary idea of an animal, its protection and legal standing. Crossing over from international and European legal sources, the thesis gradually shifts its focus on Czech legislature which has undergone marked changes over the last year, namely through the amendment 246/1992 Sb. aimed at eliminating animal abuse. Constituting a key aspect of the work, specific terminology is discussed in chapter 3. Terms such as animal or abuse are clarified consulting the law. As the title makes evident, the pivotal chapters of the thesis provide a more detailed delineation of the legal regulations concerning livestock and furbearers. Individual sub- chapters then discuss the particularities of their breeding, welfare, transportation...

The impact of intracytoplasmic sperm injection on succesful development and fertility in selected mammal species
Kaufman, Jonáš ; Petelák, Aleš (advisor) ; Petr, Jaroslav (referee)
5 Abstract This thesis aims to summarize the current knowledge about the development and reproductive capacities of individuals conceived by artificial conception, especially intracytoplasmic sperm injection (ICSI), and to make a comparison with naturally conceived ones. The focus is primarily on human assisted reproduction, even though scientific work with human gametes and embryos faces ethical difficulties. However, the main objective is to determine whether ICSI has a negative effect on offspring, partially using results from animal models. Furthermore, this thesis compares birth outcomes, incidence of birth defects, cognitive and reproductive abilities and both genetic and epigenetic integrity of individuals conceived naturally with those conceived via ICSI. As of yet, according to available information, ICSI appears to be a safe artificial method of reproduction. Poor results may often either be explained by the reduced fertility of parents, or their significance is negligible. Keywords: artificial fertilization, ART, ICSI, reproduction, offspring, mouse, livestock, human
