Published Article / A study was conducted to determine the differences between four breeds in respect of coat score, hide-thickness, tick burden and body condition score. The study was comprised of 40 heifers - 10 of each breed, namely Afrikaner, Braford, Charolais and Drakensberger. A subjective system of coat scoring, ranging from extremely short to very woolly, was used. Body condition score was measured subjectively, with 1 being emaciated and 9 being obese. Hide-thickness (in mm) and tick count were also determined. Between August 2007 and early March 2008, measurements were carried out on the same 10 animals of each breed, with highly significant differences in body condition score, hide-thickness and tick count being observed between the breeds in all instances. Coat scores differed significantly between breeds in the earlier and latter stages of the study becoming less significant midway through. A significant difference in body condition score within breeds was also found, while hide-thickness did not differ significantly within breeds.

Ve své diplomové práci zpracovávám urbář táborského panství. Urbář byl sepsán kolem roku 1510. údaje z urbáře porovnávám ještě s dalším účetním materiálem, který se pro panství dochoval z 15. a 16. století. jedná se o nejstarší urbář z let 1469-1486 a výběrčí rejstříky z let 1498 (svatohavelský), 1502 (svatohavelský), 1503 (svatojiřský) a 1530 (svatojiřský a svatohavelský). Jelikož bylo táborské panství rozsáhlé, vybrala jsem si 24 vesnic, které budu zpracovávat podle údajů v pramenech. V pramenech sleduji vývoj počtu usedlých (držitelů gruntů či hospodářství), výměry polností zapsaných k vesnicím a jednotlivým usedlým, úroční dávky a formu dávek a změny držitelů gruntů. Annotation I adept the urbar Tabor's manor in my diploma's work. The urbar was writen around year 1510. I compare dates od the urbar with another accounting materiál, which it preserved from 15th ant 16th of century for manor. It is the oldist the urbar between 1469 and 1486 and tax collector index form year 1498 (sainthavel's), 1502 (sainthavel's), 1503 (saintgeorge's) and 1530(sainthavel's and saintgeorge). The Tabor's manor was extensive, I chaose 24 vilages, which I will adept accord dates in historical source. In historial source I monitor process numer of rezidents (farm's tenants and homestead's tenants), areas of fields,...

Initially the present study was confined to the effects of ultraviolet irradiation on acid-soluble collagen. Such a study was undertaken in order to demonstrate the critical role played by tyrosine and phenylalanine in the intermolecular interaction of the telopeptides protruding from the rigid parent collagen molecule. Since both tyrosine and phenylalanine are photosensitive, and because the collagen telopeptides are relatively rich in these aromatic amino acids, carefully controlled degradation studies involving telopeptide liberation could be made. It became increasingly apparent during the course of investigation, that a better understanding of the subunit composition of thermally denatured acid-soluble collagen was necessary if a satisfactory interpretation of the irradiation studies was to be made. A subsequent study of the subunit composition of thermally denatured acid-soluble collagen resulted in the isolation and characterisation of two major and two minor dimeric components as well as the α- and β - subunits. Three acidic telopeptides and three basic telopeptides were also isolated from acid-soluble collagen during the course of the present study. The presence of the dimeric components while related directly to the method of preparation, suggested that acid-soluble collagen was largely dimeric in nature. Such a conclusion suggested an intermolecular rather than an intraolecular relationship between neutral-salt-soluble and acid-soluble collagen. While it is currently accepted that an intramolecular relationship exists between neutral-salt-soluble and acid-soluble collagen, such a relationship does not satisfactorily explain the very different solubility characteristics displayed by these soluble collagen extracts. With this in mind, and using the study on the subunit composition of thermally denatured acid-soluble collagen as a basis for comparison, the intra and intermolecular relationship between neutral-salt-soluble and acid-soluble collagen was investigated using ultraviolet and gamma irradiation. The effects of ultraviolet and gamma irradiation on soluble collagen preparations proved very similar. Although collagen samples were irradiated in solution from an ultraviolet source; and under anhydrous conditions from a gamma source, much the same degradation mechanism resulted. The initial depolymerisation of dimeric material followed by peptide fission, yielding irradiation-resistant crystalline portions of the parent triple helix, took place in both instances. At the same time, both studies indicated no significant differences in the intra or intermolecular structures of the neutral-salt-soluble and acid-soluble preparations investigated. The dimer content of neutral-salt-soluble collagen preparations was, however, noted to be smaller. To current methods for the preparation of soluble collagens, it may be concluded that such preparations are peptideless to some degree. While the native tropocollagen monomer with its full complement of telopeptide side chains may actively undergo linear polymerisation resulting in fibre formation, the soluble collagen preparations referred to above may only aggregate in a rather random fashion.

Growing natural disasters, catastrophes, indrustry accidents, mass disasters and dangter of usingt modern technologies are reason for serious crisis situations when huge damages arise and there are also human victims in these affected areas. Above all local authorities and integrated rescue system give the first aid to the poeople there. Logistical operations are used to mitigate the impact of this crisis situations too. Also the thesis has got a purpose to find out and evaluate the security of population´s protection in communities with extended activity Tábor, Soběslav and Jindřichův Hradec, to find out their readiness and in this way to confirm or refute the research question. It was determined as follows: Is logistic and its acivities determined to secure the people in chosen communities with extended activity sufficient to manage crisis situations and emergencies? Nowadays huge attention is paid to population´s security. In the theoretical part of the thesis the necessary terminology is defined which goes through the whole work. Individual chapters are dedicated to the description of local government units and solutions of emergencies. In other capters the security of population is described there are legislation of warning, hiding, evacuation, emergency survival and demarcation of integrated rescue system. Logistical problems are described, its historical progress and in particular chapters there are logistical goals, logistical activities, logistic and population´s security.There is also defined a role of State fuel reserves, units of the volunteer firefihters and non governmental non profit organisations. Methodics of this thesis consisted in assemby of literary sources regarding given issues. Then legislation in force of the Czech republic was used. By processing the internet sources were used too above all to access to legislation in force in full and then oficiall websites of Home office of the Czhech Republic, State fuel reserves, Central government authorities which deal with given issues. Qualitative research where technical, material and financial security was regarded in chosen areas was used in this thesis. Structured interview with emergency managment personnel of communities with extended acivities were used for obtaining data where activities implemented within the municipality werwe observed not in terriorial scope of the commuinity with extended activity. For finding the state of readiness if the activities aimed at protection population in chosen communities are sufficient the comprehensive index of readiness was chosen. Subsequently analysis and comprasison of the issues were made. Based on the evaluation the recommendation for improvement of readiness of the chosen communities were suggested at the and of the thesis. Then own conclusion of the thesis inform about fulfillment of the stated objectives and based on results said in this thesis about positive answer to given search question.

Orientador: Roberto de Oliveira Roça / Resumo: Um total de 180 bovinos Bos indicus (Nelore), terminados em confinamento, foi dividido em grupos com 6, 12 ou 24 horas de jejum pré-abate para verificar se a redução deste tempo resulta em melhor condição higiênica e sanitária durante o processo de abate. Amostras de fezes pré e pós-jejum, de pele e de carcaça foram colhidas e analisadas para ocorrências e contagens de bactérias aeróbias mesófilas, Escherichia coli genérica, coliformes totais, assim como, E. coli produtora de toxinas Shiga (STEC) e enteropatogênica (EPEC). As amostras de fezes também foram analisadas quanto ao pH e os teores percentuais de matéria seca (MS%) e de fibras em detergente neutro (FDN%) e ácido (FDA%). Os dados foram analisados com modelos logísticos, análises de variância e regressões, ao nível de 5% de significância. A extensão do tempo de jejum pré-abate reduziu a MS%, mas elevou o pH, FDN% e FDA% das fezes. O gradual aumento do jejum pré-abate resultou em maior excreção fecal de STEC (stx1 e stx2), entretanto, com decréscimo de aeróbios mesófilos, mas sem interferência na E. coli genérica. A extensão do tempo de jejum pré-abate também resultou na maior contaminação da pele por STEC (stx1) e EPEC, assim como, das carcaças por aeróbios mesófilos, E. coli genérica e coliformes totais. Dessa forma, conclui-se que a condição higiênica e sanitária durante o processo de abate de bovinos pode ser melhorada com a redução do tempo de jejum pré-abate.

Para as indústrias da carne isto pode representar a redução de custos operacionais e com a infraestrutura dos currais de abate, menos condenações e falhas no controle de produção, maior rendimento produtivo e incremento na validade comercial. A redução de STEC, além de ser um fomento à saúde publica, constitui-se em um estimulo à economia brasileira pela redução de barreiras comerciais e menor devolução de mercadorias. / A total of 180 Bos indicus (Nellore) cattle finished in feedlot were divided into groups of 6, 12 or 24 hours of pre-harvest fasting to verify if time reduction results in better hygiene and sanitary conditions during the slaughter process. Pre-fasting and post-fasting samples of feces, and post-fasting samples of hide, and carcass were collected and analyzed for the occurrence and counting of mesophilic aerobic bacteria, generic Escherichia coli, total coliforms, as well as Shiga toxin-producing E. coli (STEC) and enteropathogenic E. coli (EPEC). The feces samples were also analyzed for pH and content percentage of dry matter (DM%), neuter detergent fiber (NDF%) and acid detergent fiber (ADF%). Data were analyzed with logistic models, analyses of variance and regressions at 5% significance. The extension of pre-harvest fasting time reduced DM% but increased pH, NDF% and ADF% of feces. The gradual increase of pre-harvest fasting time resulted in greater fecal excretion of STEC (stx1 and stx2) with reduction of mesophilic aerobic bacteria, but without interference in generic E. coli. The extension of this time also resulted in greater contamination of hide by STEC (stx1) and EPEC as well as of carcass by mesophilic aerobic bacteria, generic E. coli and total coliforms. Thus, it was concluded that the hygiene and sanitary condition during the slaughter process of bovines can be improved with the reduction of pre-harvest fasting time. For the meat industry, can represent a reduction of costs with operations and facilities of lairage pens, less with condemnations and failures in the production control besides a greater productive yield and increment in the commercial validity. STEC reduction, besides being a development in public health, becomes a stimulus to the Brazilian economy by decreasing commercial barriers and return of goods. / FAPESP: 2015/02208-3 / FAPESP: 2014/01109-9

Content: Microwave was used as a thermal source to extract collagen acid from the cattle hide in the present work. The effects of microwave on collagen extraction yields were studied under different microwave temperatures, time and hide-liquid ratio. The optimal extraction process was obtained by an orthogonal experiment, and the composition, structure and properties of the extracted collagen were characterized by amino acid analysis, SDS-PAGE, FTIR, UV-Vis, CD, FL, and VP-DSC. The results showed that the extraction rate of collagen was positively correlated with temperature, time and hide-liquid ratio. Under the condition of 35 °C, 6 h and 1:30 of solid-liquid ratio, the extraction proportion of collagen extracted under microwave was the highest, reaching to 13.40 %. The extracted collagen was identified as type I collagen by Amino acid analysis, and the graphic pattern of SDS-PAGE, FTIR and UV-Vis showed that the extracted collagen was similar to the standard type I collagen. Also, the results suggest that the triple helical structure exists still in the extracted collagen. The transition from triple helix to random coil of the extracted collagen was 41 ℃. These results provide a scientific basis for microwave technology for the extraction of collagen.
