Poziom makro- i mikroelementów w surowicy krwi zdrowych i chorych żubrów

The purpose of the work was to find out whether alimentary deficiences had any influence on the occurrence of diseases of the sexual organs in aurochs. The level of Ca, P, Na, K, Mg, Zn, Cu, protein and glucose was determined in 34 animals aged from eight months to twenty years. Besides, the content of Ca, P, Na, K, Mg, Fe, Zn, Cu, and Mn was evaluated in hay which was being given to the aurochs in the winter season. The animals were divided into 3 groups: a) Healthy animals without any signs of disease in the genital organs, b) Male aurochs with lesions on the prepuce and phallus noted clinically and at necropsy, c) Aurochs with parasitic invasion (F. hepatica) of the liver, lungs and alimentary tract (roundworms). The studies did not confirm the suggestions that alimentary deficiences influenced the occurrence of lesions in the sexual organs. The lower level of Ca, P and Mg in the serum of the aurochs was attributed to the deficiences of these elements in hay.
