Selenium has been known for two centuries and its biological activities have been studied for nearly a hundred years, however the problem of Se deficit has still been persisting both in humans and animals. The cause of Se deficit in animals may be low Se level in soil. This mainly applies to cattle and sheep with their direct link to soil via roughage. The risk of Se deficit in pigs and poultry is lower due to lower dependence on soil Se level in the region and Se fortification in feed mixes. The present research focuses on the effects of Se on meat and egg quality, antioxidant activity of Se, effects on fatty acid levels, activity of glutathione-peroxidase, or the effect of Se on the immune system. Ensuring natural Se supply in human nutrition by food of animal origin, mainly poultry meat and eggs (the "functional foods"), is another area to which extensive attention has recently been paid.

“…Selenium is usually added to feed in inorganically or organically bound forms − sodium selenite and selenate vs. selenomethionine, selenium proteinate, lactate-protein selenium complex, seleniumenriched yeast, selenium-enriched alga Chlorella, selenium-enriched alga Scenedesmus quadricauda, dimethylselenonium propionate etc. (Trávníček et al, 2008(Trávníček et al, , 2010Heindl et al, 2010;Skřivan et al, 2010a, b;Wang et al, 2011). In some experiments it was documented that the organic form of selenium (especially selenomethionine) is more available than inorganic forms (Pavlata et al, 2001; Gunter et al, 2003; Kuricová et al, 2003Weiss and Hogan, 2005; Guyot et al, 2007; Pechova et al, 2008Steen et al, 2008;Sevcikova et al, 2011;Pavlata et al, 2011a).…”

During pregnancy and lactation the mother's demands for selenium increase because selenium is necessary for the foetus and the newborn kids (Smith and Picciano, 1986; Anan et al., 2009). A decrease in the concentration of selenium in the blood was confirmed during parturition and beginning of lactation . Selenium concentrations also decreased in the liver of pregnant animals as compared to the non-pregnant ones; it was discovered that selenium The goal of the experiment was to compare the effect of four different forms of selenium (Se) − sodium selenite (SS), lactate-protein selenium complex (SL), selenium enriched yeast (SY), and seleniumproteinate (SP) supplemented to pregnant goats on Se concentration and glutathione peroxidase (GSH-Px) activity in the blood of goats on the day of delivery and also on Se concentration and GSH-Px activity in the blood of newborn kids. The experiment involved 33 pregnant goats of White Short-haired breed. The supplementation started 6 weeks before the parturition. The goats were divided into 5 groups: control group C, not supplemented, and 4 trial groups (SL, SP, SS, SY), which received Se in the above stated forms by the means of supplemented pellets (300 g per animal per day) at a rate 900 μg Se/kg of dry matter. The average Se concentrations in the blood of the goats were 79.6 μg/l in group C, 152.6 μg/l in group SL, 167.1 μg/l in group SP, 144.9 μg/l in group SS, and 152.9 μg/l in group SY. Selenium concentrations in all 4 trial groups were significantly higher (P < 0.01) than in control group, however no significant difference was found between individual trial groups. Likewise, the activity of GSH-Px in goat blood increased significantly in all supplemented groups compared to the controls; however we did not discover any significant differences in activity of GSH-Px between the individual selenium-supplemented groups. The Se concentrations in the blood of kids were significantly (P < 0.01) higher in the selenium-supplemented groups (SL -94.9 μg/l, SP -87.5 μg/l, SS -87.6 μg/l, SY -92.5 μg/l) than in the control group (C -49.4 μg/l), but we did not discover any differences between the individual experimental groups. The activity of GSH-Px in the blood of the kids tended towards higher values in the supplemented groups than in the control group, but the values were significantly higher (P < 0.05) only in groups SY and SL. We have found significant correlation between GSH-Px activity and Se concentration in the blood of goats (r = 0.86) and newborn kids (r = 0.95). Likewise, there was significant correlation between Se concentration in the blood of goats and their kids (r = 0.74). We discovered that the kids are reaching physiologically only about 60% of Se status in whole blood in comparison with their mothers. Our results are suggesting that all the above forms of Se were similarly utilised and transferred into the foetus in the goats.

“…After 28 days of storage, however, the difference between the sources of Se disappeared. Selenium increases lipid stability via the activity of Se-dependent glutathione peroxidase, which is an enzyme that catalyzes the reduction of hydrogen peroxide and organic peroxides (Behne and Kyriakopoulos, 2001;Wang et al, 2011b;Pavlata et al, 2012). Supplementation of the basal diet with vitamin C significantly reduced oxidative stability of yolk lipids, indicating that vitamin C acted as a pro-oxidant.…”

Two hundred and forty laying hens were fed diets supplemented with vitamin C and selenium (Se). Vitamin C was added at 0 or 200 mg/kg, and Se was added as sodium selenite or selenized yeast at 0.3 mg/kg. The feed intake and egg production were measured, and egg quality parameters were determined. Supplementation of the basal diet with Se significantly increased the laying performance; however, vitamin C significantly decreased feed intake and egg production. Vitamin C increased vitamin E concentration in the yolk. Both selenite and Se-enriched yeast increased the vitamin E concentration in the yolk and the Se concentration in the yolk and albumen. The oxidative stability of yolk lipids was improved in hens fed diets supplemented with sodium selenite, but not in those fed diets supplemented with Se-yeast. After 28 days of storage, however, the beneficial effect of selenite on lipid stability ceased. The supplementation of the basal diet with vitamin C significantly worsened the oxidative stability of yolk lipids, indicating that vitamin C acted as a pro-oxidant. Thus, vitamin C increased the laying performance and influenced some traits of egg quality. The combined supplementation of vitamin C and Se did not prove to be successful.
