Seasonal dynamics of selected blood parametres of selected flesh breeds of sheep bred in foothills conditions
ŽÁČKOVÁ, Klára
Sheep breeding is nowadays a developing branch of agriculture again. There is a lot of different breed and they react distinctly on the same conditions of the enviroment. Sheep of breeds charollais, suffolk, šumavská ovce and valaška bred in similar conditions were observed in spring and autumn of years 2007 and 2008. In these seasons were taking blood samples (from {$\pm$}7{--}24) ewes and lambs and were analyzed in hematology laboratory. There were determined haemoglobin level, haematocrit indicator, erytrocytes and leucocytes levels, glucose, cholesterol, triglycerides levels, urea and plasmatic proteins, activity of ALP and GMT enzymes, phosphor, calcium, magnesium, zinc and copper levels. The main objective of this project was determine seasonal changes in observed parametres. Next objectives were determine different changes in blood parametres in different breeds and different aimes of breeds. There were recognized that all the observed breeds don`t react the same way on similar conditions. There were not provably determined seasonal changes in observed parametres, but average Hb level was higher in autumn than in spring. Urea level was conversely higher in spring season than in autumn. The demostrable fact is, that the similar conditions induce different answers not only in different breeds but also in different aimes of breeds.

The ecological aspect emanation of zinc and copper in the cattle
JURKOVÁ, Petra
The objective of my diploma thesis was to determine the ecological impact of zinc and copper on the dairy and beef cattle breeding in the South-West Bohemia region at the farms located in the Šumava Protected Landscape Area, at the elevation from 750 m to 1070 m. The research included 4 cattle breeding farms, Posobice and Nemilkov {--} dairy cattle, and Hartmanice, Keple {--} beef cattle. In my thesis, I first evaluate the importance of zinc and copper as important mineral matters and their overall influence of the cattle organism. Furthermore, I evaluate their manifestations when these matters are lacking or in surplus in the organism. The final part of the thesis comprises two areas of findings. The first part focuses on the total intake in feed and mineral additives, the level of their content in blood plasma and their quantity excreted by cattle in the individual dairy and beef cattle breeding farms specified above. The second part researches the release of zinc and copper to the environment.
