“…The [Se] egg due to the organic Se supplement in our study were in agreement with those previously reported in other studies (Moksnes, 1983;Payne et al, 2005;Na et al, 2006;Vukasinovic et al, 2006;Chantiratikul et al, 2008). We found that both [Se] egg and total egg Se were linearly related to [SE] diet and intake ( Figure 2).…”

“…The high dietary Se levels used in this study did not affect feed intake, egg production, or egg weight, which is in agreement with previous studies (Moksnes, 1983;Paton et al, 2002;Payne et al, 2005;Na et al, 2006;Vukasinovic et al, 2006;Chantiratikul et al 2008). This lack of an effect on production indicates that high dietary levels of organic Se do not negatively affect the welfare of the hen.…”

“…Although eggs have been shown to be an effective vehicle for supplementing Se in the diet (Surai et al, 2007), relatively few studies have fed hens diets containing enough Se to produce eggs at these levels. Furthermore, the response of egg Se levels to high dietary Se has been variable (Moksnes, 1983;Payne et al, 2005;Na et al, 2006;Vukasinovic et al, 2006;Chantiratikul et al, 2008).…”

Selenium is an essential trace element with a recommended dietary allowance for human adults of 55 μg/d. However, there is evidence that greater dietary intakes may have possible health benefits, including a reduction in the risk of cancer. Several studies have shown the feasibility of enriching eggs using organic Se and that Se-enriched eggs are an effective way to supplement human diets. However, few studies have examined the response of egg Se concentration to high (>1 μg/g) dietary organic Se intake by the laying hens. The objective of the current study is to examine the effect of higher dietary organic Se levels on production, egg mass, and egg Se levels. These were assessed by feeding 3 breeds of laying hens (Barred Plymouth Rock, Lohmann Brown, Lohmann White) a basal diet containing 0.3 μg of Se/g of diet as Na2SeO3. Into this diet, Se yeast (SelenoSource AF 600), an organic source of Se, was added at 1.0, 2.4, or 5.1 μg of Se/g of diet for 4 wk. Feed consumption, egg production, and egg mass were not affected by the dietary Se concentration in all 3 breeds. Within the range of Se levels employed in the laying hens' diet, egg Se content increased linearly as dietary levels of Se increased. The results of this study indicate that feeding up to 5.1 µg/g of Se will not affect egg production and the welfare of the laying hen and is a practical way of producing Se-enriched eggs for the consumers.

Selenium was initially considered toxic to humans, but it was then discovered that selenium is essential for normal life processes. Selenium plays important roles in antioxidants. It is expected that chitosan microcapsules containing nano-selenium will be able to be used as a key material in bio-medical and cosmetic applications. The high concentration of chitosan derivatives guaranteesincreased antioxidative activity. Both inorganic and organic forms of selenium can be nutritional sources. The antioxidant properties of selenoproteins help prevent cellular damage from free radicals. The objective of this experiment was to study the antioxidative activity of chitosan nano-selenium. Our experiments were divided into five groups, in the presence of various concentrations(0.1%, 0.3%, 0.5%, 0.7%, and 0.9%) of chitosan. We performed an assessment of the antioxidant properties and cytotoxicity of respective concentrations of chitosan nano-selenium. The antioxidant activity was examined by the free radical scavenging activity on 1,1-diphenyl-2-picrylhydrazyl(DPPH) assay. The cytotoxicity effect was measured by means of 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay. As a result, the electron donating abilities of 0.1%, 0.3%, 0.5%, 0.7%, and 0.9% of chitosan nano-selenium exhibited effective andioxidant scavenging activity at 12.5 ㎍/㎖ against DPPH radicals. 0.3% chitosan nano-selenium did not show cytotoxicity on human keratinocytes. In general, the cytotoxicity of 0.1% and 0.9% chitosan nano-selenium showed the lowest effects. Though low cytotoxicity of 0.5% and 0.7% chitosan nano-selenium exhibited 29.67% and 38.4% against human keratinocytes on adding 100 ㎍/㎖ and 50 ㎍/㎖, respectively, cell vitality was recovered with 200 ㎍/㎖. These findings support the notion that chitosan nano-selenium may be useful as a new active ingredient source for bioactive compounds.
