The theoretical part of my thesis is based on a study of specialized literature and interview. It contains two parts focused on a history of breeding and the importance of breeding today with an interest on importance of school breeding. The present state of hobby breeding at Primary Schools in the Czech Republic was surveyed in frame of two questionnaires. Teachers and directors of Primary School were respondents of the first investigation, students of the Breeding School of the second one. In both surveys, the respondents were asked about actual existence of breeding at their school, farmed species, housing conditions and their attitudes and motives regarding this issue. Opinions of psychologists regarding this issue are a part of interviews presented in the first part of the work. There is a possibility to compare three insights on the same subject - by teachers, students and psychologists. Part of my thesis contains also a comparison of outcomes with similar research. Regrettably, there is a lack of literature data regarding the issue of school breeding.

Tasks: 1. Analyze the condition of fur animal husbandry all over the world and in Lithuania; 2. Overlook main factors influencing the production of fur breeding farms (breeding technologies, diseases, herd formation); 3. Analyze and assess the economic situation of fur breeding farms and opportunities in fur market. Material and methods. Scientific literature was analyzed, structured and compared for theoretical research of factors influencing breeding technologies and fur market of foxes and minks. Economical activity data of „Vilkijos ūkis“ (2004 - 2007) was used in this research. Practical part of the research is prepared using mathematical statistical data processing methods of primary and secondary information systematization and generalization. Data batching, resumptive rates formation methods were used for data analysis. There was used calculation of dynamics line average indexes, average levels, absolute alterations of dinamics lines, alteration rates. Results of the work: 1. All fur breeding animal farms in Lithuania sell their production in equal conditions – foreign auctions. Demand and price of different fur kinds is very hesitative, because fur market is dictated by heavily forecasted factor – fashion trends; 2. Amounts of farm production are stable – though general number of fur... [to full text]

Criminal law protection of animals against cruelty and other inappropriate treatment Abstract This diploma thesis deals with animal protection in the Czech Republic from perspective of criminal law as a legal instrument ultima ratio. Primary goal of this thesis is to analyse legal regulation in Act no. 40/2009 Coll., Penal Code, de lege lata and evaluate possibilities de lege ferenda. Within current legal regulation this thesis works with articles 302, 302a and 303 of Penal Code and the current legal regulation is compared with the previous one. Particural attention is dedicated to Act no. 114/2020 Coll., which established entirely new crime into the Czech legal system called Breeding Animals in Iappropriate Conditions and widened the listing of penalties stated in article 52 of Penal Code by penalty of prohibition of keeping and breeding animals. Particular novelties are analysed in detail and the thesis also responds to the most frequent arguments in favour and against passing the new legal regulation. Secondary goal of the thesis can be seen in sociological considerations and comparative studies. Diploma thesis consists of five chapters, which divide more minutely further. The first chapter introduces key concepts of animal protection area, mainly the term "animal". Fundamental terms are defined in...

The objectives of this study were to quantify morphological and functional structures of the testicular parenchyma, calculate gonadosomatic, tubulosomatic, leydigosomatic and Sertoli cell indices; describe the duration of the seminiferous epithelium cycle (SEC) by identifying the most advanced germ cells labeled by 5- bromodeoxyuridine (BrdU); characterize the various stages that constitute the seminiferous epithelium cycle based on tubular morphology and calculate daily sperm production per gram of testis of jaguarundi (Pumayagouaroundi). For this purpose we used five adult males, one from Centro de Triagem de AniamaisSilvestres at Universidade Federal de Viçosa and four from ParqueZoológico de São Paulo. After chemical restraint animals had their body weight, body size, and diameter of the chest measured, and underwent testicular biopsies in order to obtain biological material for histological and immunohistochemical evaluation. In the studied Jaguarundis the average weight was 6.6 kg, being that 0.032% of it was allocated in testis (gonadosomatic index), which has 57.36 m of seminiferous tubule, coming to a tubulosomatic index of 0.027% . The total number of Leydig cells found in this species was 72.96 million cells and leydigosomatic index was calculated at 0.001%. Eight stages of the SEC were described and had their relative frequencies determined based on the tubular morphology method. At SEC, pre- meiotic stage of the spermatogenic process was higher than the other ones (48.66 %). Through the use of a cell proliferation marker (BrdU) injected in the testicles, labeled cells were observed in round spermatids of stage V after 14 days of application. From this, we can conclude that a seminiferous epithelium cycle of the Jaguarundi lasts 8.4 days, and the total spermatogenic process duration is 37.8 days. The Jaguarundi presented in the seminiferous epithelium, in each cross section of the seminiferous tubule at stage I of the cycle, an average of 1.03 spermatogonia type A; 9.78 primary spermatocytes at pre-leptotene/leptotene; 10.68 primary spermatocytes in pachytene; 25.3 round spermatids. The spermatogenesis general yield in this species was approximately 18.9 cells, and each Sertoli cell was able to sustain and maintain 14.24 round spermatids. The daily sperm production found demonstrates that the Jaguarundi is an animal with a high level of production, since its production is about 51.52 million sperm per gram of testis. / As pesquisas morfofuncionais sobre o testículo aliadas aos estudos em endocrinologia, embriologia e criopreservação de gametas, produzem informações que podem ser aplicadas na reprodução assistida, favorecendo o desenvolvimento de metodologias utilizadas na conservação de espécies. Os objetivos deste estudo foram quantificar as estruturas morfofuncionais do parênquima testícular, calcular os índices gonadossomáticos, tubulossomáticos e leydigossomáticos e de célula de Sertoli; descrever a duração do ciclo do epitélio seminífero pela identificação das células germinativas mais avançadas marcadas pela 5-bromodeoxiuridina (BrdU); caracterizar os diversos estádios que constituem o ciclo do epitélio seminífero com base na morfologia tubular e calcular a produção espermática diária por grama de testículo de gato mourisco (Puma yagouaroundi). Para isso foram utilizados cinco animais machos adultos, sendo um proveniente do Centro de Triagem de Animais Silvestres da Universidade Federal de Viçosa e quatro do Parque zoológico de São Paulo. Após contenção químicaos animais tiveram suas medidas corporais de peso, tamanho corporal, e diâmetro de tórax mensurados, foram também submetidos a biópsias testiculares a fim de se obter material biológico para avaliação histológica e imunohistoquímica. Nos gatos mourisco estudados a média de peso foi de 6,6 kg sendo desses, 0,032% alocados em testículo (índice gonadossomático) que possui 57,36 m de túbulo seminífero perfazendo um índice tubulossomático de 0,027%. O número total de células de Leydig encontradas nessa espécie foi de 72,96 milhões de células e o índice leydigossomático foi calculado em 0,001%. Foram descritos e determinada a frequência relativa de oito estádios do ciclo do epitélio seminífero (CES) com base no método da morfologia tubular. No CES a fase pré-meiótica do processo espermatogênico foi maior que as outras (48,66%). Através do uso de um marcador de proliferação celular injetado intratesticularmente (BrdU) foram observadascélulas marcadas em espermátides arredondadas do estádio V, após 14 dias da aplicação. A partir daí, pode-se concluir que um ciclo do epitélio seminífero do gato mourisco dura 8,4 dias, e o processo espermatogênico duração total de 37,8 dias. O gato mourisco apresentou no epitélio seminífero, em cada secção transversal do túbulo seminífero no estádio I do ciclo, em média, 1,03 espermatogônias do tipo A; 9,78 espermatócitos primários em pré-leptóteno/leptóteno; 10,68 espermatócitos primários em paquíteno; 25,3 espermátides arredondadas. O rendimento geral da espermatogênese nesta espécie foi de aproximadamente 18,9 células, e cada célula de Sertoli foi capaz de sustentar e manter 14,24 espermátides arredondadas. A produção espermática diária encontrada demonstra que o gato mourisco é um animal com alto nível de produção, uma vez que sua produção é cerca de 51,52 milhões de espermatozoides por grama de testículo.

Two faces of ZOO Perception of zoos from the view of their supporters and opponents The main topic of this thesis is a role of zoological gardens in the modern society, especially their importance to conservation of biodiversity as well as to progress in public education. I was interested not only in the opinions and the attitudes of the supporters of zoological gardens, but also in views of their opponents as the opposite side. In the case of the opponents I wanted to reveal if their criticism of zoos is based on negative emotions (bad feeling from breeding animals in captivity and thinking about their rights to freedom) or rise from real inadequacies (for example bad living conditions of animals). So in the theoretical part of the thesis I was concerned about contributions of zoological gardens in many ways as well as about their limitations, mostly mentioned by their opponents. To be more precise in drawing conclusions I made my own empirical research which was based on questionnaires and interviews with directors of certain zoos in the Czech Republic. The main aim of my research was not only a usual opinion poll, but also a detection of differences in opinions and personal characteristics between supporters and opponents of zoos. I also wanted to find out which aspects of zoos are highly...
