“…Likewise, Sun et al (2017) found no effect of Se sources (hydroxyselenomethionine and sodium selenite) and Se supplementation (0.1, 0.3, or 0.5 mg of Se kg -1 DM) compared to a basal diet containing 0.06 mg of Se kg -1 DM in mid lactation cows. Additionally, milk yield and composition in the present study were supported by other (Calamari et al, 2010;Gong et al, 2014;Heard et al, 2007;Juniper, Phipps, Jones, & Bertin, 2006;Ran et al, 2010;Salman et al, 2013) reporting dietary Se source did not markedly affect milk yield or composition in lactating cows.…”

“…They reported a higher BW for supplemented cows with selenite compared to yeast Se which might be due to differences in BW at enrollment. In according to the present study results, other studies investigating the effects of dietary Se source in lactating cows did not observe any change in DMI (Heard et al, 2007;Ran et al, 2010;Salman et al, 2013;Sun et al, 2017).…”

The aim of this study was to determine the effects of supplementing close-up and fresh dairy cows' diets with sodium selenite or organic sources of selenium (Se) on the dry matter intake (DMI), milk production and composition. Based on their body condition score (BCS), previous lactation milk yield and expected calving date, 24 multiparous Holstein dairy cows were balanced and randomly assigned to 4 experimental treatments. Experimental treatments were: control (basal diet without Se supplementation with 0.10 and 0.15 mg of Se kg-1 DM in close-up and fresh diets, respectively), sodium selenite supplementation (0.50 mg of Se kg-1 DM; Se-S), selenium yeast supplementation (0.50 mg of Se kg-1 DM; Se-Y) and selenomethionine supplementation (0.50 mg of Se kg-1 DM; Se-M). Neither Se supplementation nor Se source affected DMI pre-and postpartum. Milk production and composition were not different across Se sources, but concentrations of Se in milk were 14 and 10% greater for cows fed Se-M and Se-Y than for those fed control, respectively. Cows fed Se-M had lower somatic cell count than control (SCC; 173.11 vs. 318.89 cells × 10 3 Ml-1). The changes of BW and BCS pre-and postpartum were not affected by treatments over experimental period. The results of present study showed that selenomethionine supplementation compared to other sources decreased SCC in transition cows. In addition, milk Se concentrations increased in Se-Y and Se-M groups more significantly compared to the Se-S group. This indicates that organic Se had better replace inorganic Se for transition dairy cows.

“…Dietary supplementation with Se yeast in lactating dairy cows increased Se milk concentrations in Australia [147]. In China, supplementation of diet with Se-enriched yeast was more effective than sodium selenite in producing favorable cow milk with high polyunsaturated fatty acids and Se concentrations [67]. In a similar study, Holstein cows' diet was supplemented with either Se yeast or selenite.…”

“…Selenium supplementation in diets usually results in an increase of the selenium content and GSH-Px activity in the blood of calves [64], heifers [65] and fattening bulls [66]. Such positive effects become more pronounced when Se is supplemented in organic form as compared to inorganic form [65,67]. Generally, organic Se supplementation resulted in an estimated 20% increase Se level and 16% increase in GSH-Px activity in blood [68].…”

Selenium (Se) dependent enzymes play important roles in physiological functions such as thyroid hormone metabolism, strengthens anti-oxidant defense system and immune system. However, about 800 million people worldwide are believed to be deficient in Se which is attributed to low Se levels in the soil. This is because Se in plant and animal products in human diet depends upon the available Se in the soil. Deficiency of Se can be prevented or treated by adequate dietary intake or through direct supplementation. There have been reports that patients with dilated cardiomyopathy, HIV viral loads and cancer have responded to Se supplementation. However, food fortification has been found to be more efficient than supplementation. Both agronomic biofortification and genetic biofortification have been used to increase Se content of food crops and animal products. Genetic engineering makes use of key genes of Se hyperaccumulators to increase Se accumulating potential of food crops. Agronomic biofortification increases Se content of food crops by adding Se rich fertilizers to the soil or foliar application of Se. Selenium can also be added to animal diets or feedstuff to increase Se content of meat, eggs, and milk. Although inorganic forms of Se are approved as feed additives, they are less efficient than organic sources such as selenomethionine (SeMet) which is the dominant form in plants and animals. Animal products have been found to have higher Se content than plant products with fish having the highest Se content. Fruits and vegetables have a low content of Se probably because of their low protein content. Recommendations for dietary intake of Se vary with country, age and sex. There are concerns that the present recommended Se daily allowance may not be adequate due to discovery of other selenoenzymes with higher Se requirements than gluthathione peroxidase. There may be a need to review the current recommended daily allowance for Se in order to improve human health.

“…It is one of the last proteins to be affected in the event of Se deficiency. Selenium supplementation may reduce the incidence of metritis and ovarian cysts during the postpartum period [17,18], reported that adding Se to cows diet significantly increased Se content and percentage of polyunsaturated fatty acids (PUFA) in milk. Several studies have demonstrated the beneficial effects of supplemental selenium or iodide in maintaining thyroid gland and immune competence, and reducing ovarian cysts Mehdi, Dufrasne [19].…”
