“…Additionally, BCF values indicating accumulation of Se were observed when mushrooms were grown on substrates with ≥0.25 mM (P. nameko) or ≥0.5 mM (P. ostreatus and P. eryngii) Se addition. Our findings show that edible mushrooms growing analysed the content of Se in different Irish foods, found mean concentration of this element varying from 3 µg kg −1 dry weight (DW) (gluten-free bread) to 701 µg kg −1 DW (tuna, canned in brine), while Klapec et al [11], who analysed food collected from two rural regions of eastern Croatia, reported levels ranging from 7.9 µg kg −1 DW (tomato) to 859.2 µg kg −1 DW (tuna, canned). Interestingly, Se content in wild edible mushroom species has been widely studied [12][13][14][15].…”

“…Outdoor living animals that eat plants take selenium in the form of selenomethionine (SeMet) in concentrations that depend on selenium concentration in soil, which can vary considerably according to area (Reilly 1996). Klapec et al (2004) reported low concentrations of selenium in soil on the territory of Croatia because of which the selenium content in plant and animal foodstuffs was relatively low (egg = 52.5 ng/g; chicken meat = 115.3 ng/g; onion = 12.4 ng/g; potato = 7.2 ng/g). As a microelement, selenium has manifold importance in animal feed.…”

Effects of Dietary Selenium Source and Storage on Internal Quality of Eggs

A 4-week experiment was carried out on 360 laying hens of the Hy Line Brown hybrid. Laying hens were divided into three groups (C, E 1 and E 2 ) with 120 hens in each group and kept in 24 cages. Hens were fed layer diets containing 18% of crude protein and 11.60 MJ ME. Hens in the control group C were fed diets that contained 0.2 mg/kg of inorganic selenium (sodium selenite). Experimental groups E 1 and E 2 were given diets with increased concentrations of selenium as follows: E 1 = 0.4 mg/kg of selenium (sodium selenite), E 2 = 0.4 mg/kg of organic selenium (SelPlex). Selenium concentration in diets affected significantly the content of selenium in albumen (P < 0.001) and yolk (P < 0.05). The highest concentration of selenium was determined in albumen and yolk of eggs produced in group E 2 (345 ng/g and 783 ng/g, respectively), then in eggs of group E 1 (230 ng/g and 757 ng/g, respectively), and group C had the lowest concentration of selenium in albumen and yolk (181 ng/g and 573 ng/g, respectively). After 28 days of storage at 4 °C, the eggs containing organic selenium had more freshness (VN: C = 32.9, E 1 = 2.60, E 2 = 2.11). It was concluded that higher concentration of organic selenium in eggs was a limiting factor in metabolic processes, which positively affected the indicators of egg freshness. Organic selenium, inorganic selenium, albumen, yolk, egg freshnessSelenium is found in two forms in nature: inorganic and organic. Inorganic selenium refers to different minerals such as selenite, selenate and selenide, and organic selenium is related to amino acids, methionine and cysteine. Outdoor living animals that eat plants take selenium in the form of selenomethionine (SeMet) in concentrations that depend on selenium concentration in soil, which can vary considerably according to area (Reilly 1996). Klapec et al. (2004) reported low concentrations of selenium in soil on the territory of Croatia because of which the selenium content in plant and animal foodstuffs was relatively low (egg = 52.5 ng/g; chicken meat = 115.3 ng/g; onion = 12.4 ng/g; potato = 7.2 ng/g). As a microelement, selenium has manifold importance in animal feed. Its antioxidant properties help protect animals from free radicals caused by oxygen metabolism. Moreover, selenium strengthens the immune system and boosts growth and feathering. As a dietary supplement, selenium reduces negative effects of stress in chickens kept in intensive production conditions, reduces mortality rate of one-day chickens and enhances quality of poultry products. One of the possibilities of enriching feed with selenium is to supplement it with plants fertilized with selenium (MacLeod et al. 1998). Another possibility is to supplement selenium preparations to commercial mixture fed to animals in order to design animal products that differ in their nutritive values from other conventional products available on the market.The aim of our study was to determine the effects of supplementation of organic and inorganic selenium in increased concentrations to the...

“…Se deficiency stays in some students, especially female students. Therefore, it is important to strengthen the supply of Se-rich foods for school children such as seafood, eggs, meats, chicken, dry fruits, and legumes, as others such mushrooms and garlic [30,[62][63][64][65]. The dietary Se intake survey of students in their school and family is needed to deeply study the relationship between hair Se levels and daily Se intake, as well as its improvement impact on the prevention and control of KBD in Tibet.…”

Previous studies have shown that the selenium (Se) deficiency is an important factor for the etiology of KashinBeck disease (KBD). Although KBD is presently controlled in most regions of China, it is still active in the Tibetan Plateau. The present study aimed to assess the nutritional status of selenium in school children by using the Se level in hair as a biomarker in KBD endemic areas of Lhasa in Tibet, China. Hair samples of 155 school children aged 6-15 years were collected in both KBD areas and non-KBD areas of Lhasa in 2013. The Se level in the hair samples was determined by inductive coupled plasma mass spectrometry (ICP-MS). The average concentration of Se in children's hair was 0.232 μg/g in KBD areas of Lhasa, which was significantly higher than the data reported decades ago. A significant difference in hair Se was observed between the boys (0.255 μg/g) and the girls (0.222 μg/g) in the studied KBD areas (P<0
