“…It has been demonstrated that selenium from organic Se source is deposited mainly in the albumen whereas selenium from inorganic Se source is deposited mainly in the yolk [27]. In contrast, other authors have reported higher Se deposition in the egg yolk rather than albumen from hens fed diets supplemented with SY [24,28,29].…”

The objective of this experiment was to investigate the selenium distribution in eggs from hens fed diets supplemented with Se from sodium selenite (SS) or selenium-enriched yeast (SY). One-day-old female chickens of Hy-Line Brown breed were randomly divided into four groups according to dietary treatments and, for the subsequent 9 months, were fed diets which differed only in the form or amount of Se supplemented. During the whole experiment, group 1 (control) was fed basal diet (BD) with only background Se level of 0.13 mg/kg dry matter (DM). Diets for groups 2 and 3 consisted of BD supplemented with an Se dose of 0.4 mg/kg DM either in the form of SS or SY, respectively. Group 4 was fed BD supplemented with 0.9 mg Se/kg DM from SY. After 9 months of dietary treatments, the Se levels in egg yolk and albumen from hens fed unsupplemented diet were almost identical whereas eggs from hens given diet supplemented with SS showed significantly higher Se deposition in yolk than in albumen (P < 0.01). On the other hand, the feed supplementation with Se doses 0.4 or 0.9 mg/kg DM from SY resulted in significantly higher Se concentration in albumen than in yolk (both P < 0.001). The total Se amounts in whole eggs from hens in groups 1, 2, 3 and 4 were 5.1, 14.4, 22.7 and 31.6 μg Se/egg thus demonstrating the significantly higher (P < 0.001) selenium deposition in eggs from hens given feed enriched with SY than from birds fed diet with equivalent SS dose. Regardless of dose and source, the selenium supplementation to feeds for groups 2, 3 and 4 resulted in significantly increased α-tocopherol concentration in egg yolk compared to control group 1 (P < 0.001). The presented results demonstrate the different pattern of Se distribution in egg mass when laying hens are fed diets supplemented with inorganic or organic selenium sources.

“…In particular, Se-enriched yeast should be more effective than inorganic sources due to the higher bioavailability relative to the presence of huge amounts of selenomethionine (Wu et al, 2011). Furthermore, organic Se sources could have positive effects on the environment, decreasing pollution with a less toxic activity than the inorganic form of the element (Kim and Mahan, 2001).…”

The aim of this study was to evaluate the bioavailability of ingested selenium (Se) yeast in laying hens and its effects on performance, eggshell quality, and tissue Se distribution. Forty-eight ISA brown laying hens were divided into 3 treatment groups: Group C, fed a basal diet containing 0.11 mg Se/kg of feed; Group SS, fed a basal diet plus 0.4 mg/kg of feed of Se from sodium selenite; and Group SY, fed a basal diet plus 0.4 mg/kg of feed of Se from selenium yeast. Feed intake, egg mass ratio, and production performance were not affected by Se supplementation, regardless of the Se source. Egg weight (+3.61% and +2.95%), eggshell weight (+4.26% and +5.38%), and eggshell surface (+2.43% and +1.96%) were higher (P<0.05) in SS and SY than C, whereas breaking strength was increased in SY (P<0.01). Breast muscle, liver and skin Se levels were higher in SY than in C, while kidney Se content was higher in SS hens. Eggs from SY had higher Se levels than SS. Blood metabolites were not affected in SS or SY groups than C. A higher Se level was detected in eggs and breast muscle of SY hens (P<0.05). Seleniumenriched eggs and edible tissues from organic Se sources in poultry diet could improve antioxidant status in humans and reduce possible Se deficiency-related diseases.

“…Generally, Se in organic forms has better bioavailability and is less toxic compared with inorganic selenium with poor conversion and high toxicity to some extent [ 5 – 8 ]. Nowadays, various available sources of organic Se, namely, Se-enriched yeast [ 9 – 11 ], selenomethionine [ 12 – 14 ], Se-enriched probiotics [ 15 ], heterotrophically produced Se-enriched alga [ 16 , 17 ], and Se-enriched plants [ 18 , 19 ], have been investigated over time. Among these organic Se, the main organic Se source used in practice is Se-enriched yeast, in which Se is present predominantly (94 ± 5%) in the form of protein-bound L-selenomethionine [ 20 ].…”

Detailed safety assessment of sodium selenite and bioselenium (bio-Se) was conducted and the results were compared and discussed for the purpose of assessing safety of bio-Se for use in food applications. In this work, acute toxicity studies, micronucleus test, and sperm aberration study in mice, 30-day feeding test of mice, were conducted to evaluate the toxicity of bio-Se obtained from yeast with different fermentation time (transformative time: one month, three months, and six months), and the results were compared with that of inorganic Se (sodium selenite). LD50 of sodium selenite was calculated to be 21.17 mg/kg. LD50 of bio-Se obtained from yeast with different fermentation time was calculated to be 740.2 mg/kg, 915.3 mg/kg, and 1179.0 mg/kg, respectively. In the genotoxicity test, bio-Se did not show cytotoxicity and genotoxicity of mice while sodium selenite at all dose groups was significantly different from the negative group. In the 30-day subchronic oral toxicity study, sodium selenite may slow down the growth of the mice and lead to organic damage to some extent. Bio-Se had facilitated effect towards the body weight of the mice and had no significant effect on the shape and function of the important organs of the mice.
