Selenium (Se) is an important nutritional hint aspect engaging within the law of varied physiological services in either animals and people via its incorporation into selenoproteins because the amino acid selenocysteine. between many minerals Se has a unique position being the main debatable hint point with a slender hole among essentiality and toxicity. certainly there are very important environmental matters contemplating selenium as a pollutant from the only hand and worldwide selenium deficiency at the different. actually, Se deficiency is taken into account as a threat issue for the improvement of assorted illnesses in human and animals. diminished Se availability from soils because of low soil pH and utilization of man-made fertilizers is the main situation in ecu international locations inflicting insufficient Se degrees in nutrients and feeds.Furthermore, it sort of feels most probably that sodium selenite used for the final 30 years as a feed complement isn't really an optimum kind of Se and the use of natural selenium in animal diets may perhaps support to keep up optimum Se prestige in addition to excessive immunocompetence, effective and reproductive functionality. the purpose of the current quantity is to supply up to date details on numerous vital Se-related matters, together with Se prestige in Europe and methods of its development, advances in Se research and speciation in organic fabric, roles of selenium in bird, pig and ruminant nutrients. during this identify, creation of sensible Se-enriched foodstuff, the connection among selenium and mycotoxins, polyunsaturated fatty acids in addition to reoviruses also are addressed. This choice of articles will supply nutritionists, veterinarians, human medical professionals, researchers and the other readers with new insights into the fascinating international of the goddess of the moon - Selenium

2. Human selenium status in Russia Comparison of the human selenium status in the Western part of Russia with that of European countries, Byelorussia, Ukraine and Baltic countries shows a similar situation characterised by serum selenium concentration range 72-126 µg/l for Russia, 50-102 µg/l – for European countries and 48-122 µg/l – for Baltic countries, Byelorussia and Ukraine (Table 1). Data presented in Table 1 indicate only 3 regions of relatively good selenium status in Europe: Moldova, the South-Western part of Ukraine and Samara region in Russia (serum selenium values reaching 120-145 µg/l).
