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.

The evaluation of horse nutrition with chosen preparats in sommer and winter season
HANETŠLÉGROVÁ, Petra
ABSTRACT The aim of this work was to provide a detailed breakdown of horse nutrition, to mention the importance of dietary supplements. The main part deals with the basics of horse nutrition, the bare necessities of nutrients, the proportion of maintenance rations and the technique of feeding. Afterwards, I outline the properties and effects of varied herbal plants such as garlic, hemp, hyssop, white horehound, coltsfoot and oats. Flaxseed, biotin, zinc, yeast and probiotics are dietary supplements improving the quality of fur, horsehair and hoofs. The feed will be analysed by standard methods. As far as horse excrement is concerned, we are going to observe its shape, colour, consistency, pH value and smell. The assessment of horse excrement will serve as a judgement about the activity of digestive system. The ethology observations will provide information on daily activity of a horse, on particular activities, to which the horse gives its attention during a day, and the amount of time it dedicates to them. As far as horses with respiratory disorders are concerned, we will observe the signs of their health problems and the rate of these problems occurring both at rest and in action. The information will be completed by the measurement of body proportions useful to body weight calculation. The statistical and economic methods will be selected in terms of the results accomplished during the research.
