Abstract
Selenium is an important trace element that participates in numerous physiological and metabolic processes in animals and human organism. Many areas in the world are known for its lack of selenium in soil, and in crops/products, which is then reflected in its deficiency in animals and humans. In recent years, more attention has been paid to finding the optimal method/procedure in order to enrich the product with selenium. By consuming animal products enriched with selenium in the human diet, it is possible to meet their nutritional needs for selenium. By analyzing the available literature, the aim of this paper is to research: (I) the importance of selenium for animals and humans; (II) the selenium content in ruminants ´ milk with special emphasis on small ruminants milk (sheep and goats); (III) methods/procedures in enrichment of small ruminants´ milk with selenium, especially those with an emphasis on nutritional modeling and natural methods; and (IV) some of the possibilities of using milk enriched with selenium in human nutrition. In conclusion, the methods/procedures aimed at enrichment of small ruminants milk with selenium can be recommended. This includes the addition of organic sources of selenium in the diet, or biofortification of feed with selenium, also known as a natural process which may lead to positive effects on animal health, as well as positive effects on humans when consuming milk enriched with selenium, especially when selenium deficiency is prolonged.
