The theoretical part of the master's thesis contains knowledge about nutrition of goat, anatomy of the digestive tract, free radicals, selenium and ingredients of goat's milk based on available literature resources. The objective of the practical part was to experimentally determine the impact of the the addition of selenium to feeding ration for organic raised goats on qualitative and quantitative parameters of goat's milk and selenium content in goat's milk. The experiment was held on an organic farm in Prostejov area in June and July 2016, it lasted 30 days. Goat breeds raised on the farm were White Shorthaired and Anglo-Nubian. There were 12 goats studied in the experiment, divided into a treatment group (n = 6) and a control group (n = 6). Milk samples from each goat were collected at the beginning and end of the experiment The samples were analyzed in a laboratory for analysis of milk in Brno - Turany, selenium was analyzed at the Department of Chemistry and Biochemistry MENDELU. The results were evaluated and compared. The results of the experiment shows that the addition of selenium had an impact on its concentration in goat's milk but it had no effect on milk components (fat, protein, lactose, urea, somatic cell count) and milk yield.
