It is worth noting also that there is no unambiguous idea regarding the advantages
of organic forms of selenium over inorganic ones. Thus, Donald C. Mahan [1], in an
experimental comparison of various forms of selenium in the 1996 study, noted that
the use of inorganic selenium contributes to higher GSH-Px activity than similar levels
of organic. This indicates that the bioavailability of inorganic selenium may be higher
for the synthesis of this enzyme than the organic source.
At the same time V. Fisinin and T. Papazyan [9] emphasize that the organic form
of selenium in the form of Sel-Plex (Alltech Company) has significant advantages over
inorganic form - selenite or sodium selenate. In the experiment, chickens in the
experimental group were given Sel-Plex (100 mg / ton) with sodium selenite (100 mg
/ t) and sodium selenite (200 mg / ton) for the control chickens. After 15 days, the eggs
were collected and incubated. As it turned out, the withdrawability of eggs in the
experimental group amounted to 85.5%, and in the control group – 83.3%, the live
weight of the chickens of the experimental group at the age of 2 days was 52.75 g,
while the control group – 48.02 g, which was 9.9 % more. In addition, Sel-Plex
positively influenced the accumulation of selenium and vitamin E in eggs and chicken
embryos, an increase in Hau units, and increased activity of glutathione peroxidase.
In the second publication [8], the authors themselves, who prefer the Sel-I-Z, as
well as the Selenite and Sel-Plex forms, characterize the quality of semen of cocks
according to fatty acid composition, the number of re-oxidation and antioxidant
protection under the influence of inorganic (selenite) and organic (Sel-Plex) Plex
However, if you compare the results of studies with Sel-Plex and sodium selenite, then
they differ by 2.2 (evicability of eggs) – 3.2% (fertility of eggs), while Sel-Plex's cost
is 3-5 or more times higher cost of sodium selenite. Therefore, not opposed to the idea
put forward by the authors, we tend to assume that the excessive and insufficiently
reasoned advertising of organic forms of selenium is, in our opinion, somewhat
commercial in nature. Although, of course, the study of organic selenium in
comparison with inorganic forms it deserves the attention of researchers.
