Selenium in bovine plasma, soil and forage measured by neutron activation analysis

Levels of Selenium in Vegetables, Medicinal Plants and Soils from Selected Sites within the Lower Benue River Basin Development Authority Catchment, Nigeria

“…Low level of selenium that was observed in the sites might be due to leaching of essential minerals from soils and this could have resulted to losses of available selenium in the soil for plant uptake [51,38,39] [44,45,46]. Results from this study have indicated that Se in agricultural soils of LBRBDA project sites analyzed were below deficiency classification of 0.05 mg/kg [43,53]. To maintain good health, the World Health Organization (WHO) recommends minimum selenium oral intakes of 33-34 μg/day for adult males and 25-26 μg/day for adult females (35-42 μg/day for lactating females).…”

“…OFO, Oforachi (Idah LGA), site recorded the lowest soil Se concentrations with 1.0 x 10 -4 mg/kg. Low soil Se concentration observed, could due to the low soil Se in the site [43]. The low average soil Se concentration observed in the entire sites could be as a result of top soil erosions where Se partitioned itself.…”

Selenium Fertilization in Tropical Pastures

“…Cattle deficiencies have a likely relation between low Se in forage grass or supplements [26]. Thus, Se deficiency keeps as a concern, since this nutrient has been found in low levels in Brazilian diet.…”

“…When a mineral is deficient in soils, livestock needs to be supplemented. In the semiarid region, for example, a low concentration of selenium is observed [8]. Selenium is a cofactor of different enzymes such as glutathione peroxidase, which is involved in the antioxidant systems [9].…”
