A comparison of selenium concentrations in selected organs of wild boar (Sus scrofa) from industrialized and non-industrialized regions of Poland

Abstract

The aim of this study was to compare selenium concentration in the liver and kidneys of wild boar inhabiting industrialized and non-industrialized regions of Poland. Selenium concentrations in organs were determined using spectrofluorometric method. In all the animals studied, Se concentrations were a few times lower than in kidneys which may indicate too low content of this element either in the boar’s diet or the presence of a poorly absorbable form of Se. No statistically significant differences were noted in the mean Se concentrations in the liver and kidney of wild boar from industrialized and non-industrialized areas. In the case of wild boar, it seems that the level of selenium in their organs is more dependent on geochemical conditions in the specific feeding ground than on the scale of regional industrialization, and that this situation is most likely related to the specificity of wild boar feeding.

Comorbidities and concentration of trace elements in livers of European bison from Bieszczady Mountains (Poland)

“…In Poland, the average level of Se in the soil is 0.27 mg kg −1 d.w. 33 , while according to the paper of Gupta & Gupta 34 , Se level within the range of 0.1-0.6 mg kg −1 is considered a deficit. Hence, Se deficiency is often observed in the tissues of free-living ruminants in Poland, including European bison 10,11,35,36 . Furthermore, high levels of S and Mo in the soil and diet (despite the appropriate level of Cu) can significantly reduce Cu absorption in the intestines of ruminants, thus inducing a secondary deficiency of this microelement 37,38 .…”
