Abstract
Soybean is a feedstuff rich in proteins, which is, together with its by-products (meal and cake), most often used in animal diets in order to provide a good-quality protein source. The aim of this paper is to present the possibilities of biofortification of soybeans with selenium and its application in animal feeding. Soybean is a high-quality source of selenium in organic form, primarily in the form of selenomethionine. Selenium is important in human and animal feeding due to its numerous physiological functions and is usually presented in insufficient amounts in the food chain. Biofortification of soybeans with selenium, specifically the agronomic one, can be used as a qualitative method of enriching edible parts of crops/soybeans with selenium. Inorganic selenium compounds (selenate and selenite) are most often used, which the crop/ soybean transforms into an organic form that is more accessible to different organisms. The inorganic form of selenium like selenate is more bioavailable than selenite. Agrofortification of crops/forage by foliar treatment of crops is more effective than soil fertilization with selenium. The reason for this is to avoid very complex reactions which take place in the soil, causing significant differences in the absorption of selenium with regard to different environmental and soil conditions. In the available research, the biofortification of soybeans with selenium, carried out with inorganic forms of selenium, led to a significant increase in the content of selenium in soybeans, but no significant effect on the soybean yield and on the structure and functionality of soybean proteins was detected. However, there are also studies with opposite effects. There is not ample research on the use of selenium-biofortified soybean in animals feeding, especially in livestock. This could be a subject of further research, with the aim of pointing out the possibilities of using selenium-biofortified soybean in livestock feeding.
