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.
