Selenium Speciation Analysis Reveals Improved Antioxidant Status in Finisher Pigs Fed l-Selenomethionine, Alone or Combined with Sodium Selenite, and Vitamin E

Abstract: Conditions associated with selenium (Se) and/or vitamin E (VitE) deficiency are still being reported in high-yielding pigs fed the recommended amounts. Here, the dietary effects of Se source (sodium selenite, NaSe, 0.40 or 0.65 mg Se/kg; l-selenomethionine, SeMet, 0.19 or 0.44 mg Se/kg; a NaSe-SeMet mixture, SeMix, 0.44–0.46 mg Se/kg) and VitE concentration (27, 50–53 or 101 mg/kg) on the antioxidant status of finisher pigs were compared with those in pigs fed non-Se-supplemented diets (0.08–0.09 mg Se/kg).

“…Although many studies have been conducted on the tissue distribution of Se in various animal species [30,31], there is little data on how it is affected by dietary Se status in beef cattle [8,22]. The present study is the first to be carried out in Poland, an area known to suffer from Se deficiency.…”

“…Generally, the presence of selenium is determined by its concentration in blood serum [7,54,55]. For maintaining homeostasis, the human body cells require balanced nutrition and adequate micronutrients from trace elements [10,30,56]. Selenium is known to be part of the required micronutrients among the trace minerals utilized by the human body; others are antioxidants and vitamins, which are vital for performing various regenerative processes in the human body, such as immunity development for fighting pathogens and managing oxidative stress [10,32,51] (Figure 1).…”

“…Research shows that using selenium supplements higher than the recommended dose can be easily toxic, even when feeding as little as 5 to 10 mg/kg in the diet [45]. The main signs of selenium toxicity in swine that were recorded are hair loss, liver and kidney damage, edema, hoof loss, and disorders of the nervous system [56]. In poultry, the results have proven that eggshell-quality breaking strength is improved when selenium is added to the diet of laying hens [94,95].…”
