“…These outcomes consistently confirmed that the efficacy of Se from Seenriched yeast and HPSeKS was comparable, but higher than that of Se from sodium selenite when used tissue Se concentration as an indicator [19]. Numerous reports similarly observed broilers received Se from Se-enriched yeast or Seenriched alga had higher (p<0.05) tissue Se content than those received Se from sodium selenite [4,5,7,8,38,39]. On the other hand, Se from Se-enriched garlic, cabbage [10], and malt [40] did not improve Se concentrations in chick tissues, reflecting that selenomethionine is not the major Se species in these plants.…”

An experiment was conducted to determine the efficacy of Se from hydroponically produced Se-enriched kale sprout (HPSeKS) on performance, carcass characteristics, tissue Se concentration, and physiological responses of broilers in comparison to that of Se from Se-enriched yeast and sodium selenite. Three hundred and sixty male broilers, 10 days of age, were assigned to 6 groups, 4 replicates of 15 broilers each, according to the completely randomized design. The dietary treatments were the following: T1: control diet; T2: control diet plus 0.3 mg Se/kg from sodium selenite; T3: control diet plus 0.3 mg Se/kg from Se-enriched yeast; and T4, T5, and T6: control diet plus 0.3, 1.0, and 2.0 mg Se/kg from HPSeKS, respectively. The results found that dietary Se supplementation did not (p > 0.05) alter performance and carcass characteristics of broilers. Se supplementation increased (p < 0.05) Se concentrations in the liver and kidney of broilers. Heart tissue Se concentration of broilers fed Se from sodium selenite was lower (p < 0.05) than that of broilers fed Se from HPSeKS and Se-enriched yeast. Selenium from HPSeKS increased higher (p < 0.05) GSH-Px activity when compared to Se from sodium selenite and Se-enriched yeast. The results indicated that the efficacy of Se from HPSeKS was comparable in increasing tissue Se concentration, but higher in improving GSH-Px activity in Rbc when compared to those of Se from Se-enriched yeast.

“…In recent years, considerable attention has been paid to supplementing animal feed with organically bound selenium in Se-enriched yeast as an alternative to inorganic Se supplementation. The use of organic Se sources generally results in better absorption, more effective utilization and formation of larger body deposits of this microelement [12][13][14][15][16]. Se-enriched yeast obtained by Saccharomyces cerevisiae cultivation with inorganic Se source may contain >90% of its Se in the form of selenomethionine (SeMet) [17].…”

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.

“…A prevention of Se deficiency can be performed by dietary supplementation. The supply of Se in the diet depends on the country, the region, its concentration in the environment and the type of food intake (Olivera et al, 2005;Pilarczyk et al, 2010;Fairweather-Tait et al, 2011). Much of Europe, including some Polish regions, are considered areas poor in Se (Pilarczyk et al, 2008(Pilarczyk et al, , 2010.…”

The study was conducted on 60 pigs kept in individual pens. The animals were allocated to four groups. The growing-finishing pigs from the control group were fed with basic feed containing 0.3 mg selenium (Se) derived from Na 2 SeO 3 kg −1 and 60 mg of dl-α-tocopheryl acetate kg −1 . The remaining three groups were differentiated by adding 0.2 mg kg −1 Se-enriched yeast (Saccharomyces cerevisiae) and/or 60 mg vitamin E to feed (grower and finisher). Our results show that the addition of organic Se to inorganic Se commonly used in pig feed caused a significant increase in hepatic Se and muscle. This indicates the possibility of using these products as functional foods to improve Se status in humans residing within regions which are deficient in this trace element. We found no beneficial effect of supplementation with vitamin E and Se on the quality of the meat.
