“…GPx activity in liver and muscle can be increased when supplementing Se to a Se-deficient control (Zhan et al, 2007). Interestingly, we found higher GPx activity in liver raising inorganic Se from recommendation to maximum dietary EU level, indicating, that no plateau was yet reached in liver.…”

“…Higher GPx activity in liver or Cu/Zn-SOD in muscle should go in line with a decrease in TBARS concentration, as marker of lipid peroxidation, resulting in improved oxidative stability (Lu et al, 2006;Zhan et al, 2007). However, there is no correlation neither in our study (GPx v. TBARS: r = 0.042, P = 0.747; Cu/Zn-SOD v. TBARS: r = 0.248, P = 0.056) nor in the trial of Ahmad et al (2012).…”

“…Se concentration in LTL was not as markedly elevated due to Na-selenite supplementation as can be seen when Se-deficient diets serve as control (Zhan et al, 2007). Livestock does not accumulate high dietary Mn concentrations (National Research Council, 2005) as absorption and elimination via bile/faeces are well regulated.…”

“…Dietary Se or Mn can improve stability of meat, for example, during retail display (Apple et al, 2005;Zhan et al, 2007). This can be observed in reduced lipid peroxidation, weight loss or improved colour stability.…”

Data are scarce regarding combined high Se and Mn supplementation in livestock diets, however, as Se and Mn are functionally related as cofactors of glutathione peroxidase (GPx) and Mn-superoxide dismutase (SOD), respectively, beneficial synergistic effects on oxidative stability of tissues may result. This experiment evaluated the effect of an oversupply of Se and Mn within European legal limits compared with recommendations on performance, oxidative stability of the organism and meat quality in a randomised complete block design. A total of 60 crossbred gilts were fed maize-barley-soya bean meal diets formulated in a 2 × 2 factorial approach with inorganic Se (0.2 v. 0.5 mg/kg Se dry matter (DM)) or inorganic Mn (20 v. 150 mg/kg Mn DM) from 31 to 116 kg BW. Se supplementation reduced feed intake, whereas high Mn diets impaired average daily gain ( P < 0.05). Qualitative carcass characteristics were impaired by Se and Mn predominantly in the semimembranosus muscle. Activity of GPx in liver was increased by high Se diets ( P < 0.05). Mn supplementation increased catalase (CAT) activity in liver, GPx in plasma and total antioxidative capacity (TAC) in muscle, whereas it decreased CAT activity in plasma ( P < 0.05). Cu/Zn-SOD in muscle showed higher activity in high-Se-low-Mn diets but lower activity when both high Se and Mn were combined (Se × Mn P < 0.05). Mn supplementation increased Mn concentration in longissimus thoracis et lumborum, but simultaneously reduced Se concentration ( P < 0.05). Upon retail display, Mn increased lipid oxidation more pronouncedly (higher thiobarbituric acid reactive substances; P < 0.05) than Se ( P < 0.10). Despite some positive effects (Mn increased TAC, Se increased GPx, Se and Mn increased tenderness), no synergistic effects of high Se and Mn diets or an overall beneficial impact on meat quality, especially during storage, could be observed. Including the negative effects on performance, feeding Se and Mn up to the maximum legal level cannot be recommended.

“…Mateo et al (2007) reported that the drip loss of loins in 48 h in growing-finishing pigs was reduced only by SY supplementation not by SS supplementation. Zhan et al (2007) found out that SeMet was more effective in decreasing the drip loss of loin muscle than SS in finishing pigs. A possible reason for the more significant decrease in drip loss by organic Se may be that organic Se was superior to inorganic Se in increasing the antioxidant property of animals.…”

This study was conducted to investigate the effects of selenomethionine (Se-Met) and sodium selenite (SS) supplementation on meat quality, selenium (Se) distribution, and antioxidant status in broilers. A total of 360 seven-days-old Ross 308 broilers of an average body weight 162 ± 0.59 g were randomly allotted to three treatments, each of which included three replications of 40 birds. The treatments included a control diet containing 0.04 mg Se/kg and other two diets that contained 0.15 mg Se/kg supplemented by SS or Se-Met. The experiment lasted for 42 days. Selenium supplementation improved (P < 0.05) the Hunter a value of breast muscle in 8 and 16 h and decreased (P < 0.05) the drip loss of breast muscle in 24 and 48 h. Both Se sources and exposed time significantly influenced (P < 0.01) the drip loss of breast muscle. Selenium and glutathione concentrations in serum and in the studied organs were significantly higher (P < 0.05) after dietary Se supplementation while the Se-Met group showed the highest value (P < 0.05). Glutathione peroxidase activity in serum and in the studied organs was also significantly elevated (P < 0.05) by dietary Se supplementation while SS increased the glutathione peroxidase activities in pancreas and breast muscle to a larger extent (P < 0.05) than did Se-Met. The addition of Se from either source caused a significant increase (P < 0.05) in superoxide dismutase activities in tissues (except for kidney) whereas the Se-Met group was more effective (P < 0.05) than the SS group in breast muscle. Selenium supplementation increased (P < 0.05) the total antioxidant capability in serum, liver, kidney and breast muscle while the Se-Met group proved to be more effective (P < 0.05) than the SS group except for kidney. The Se-supplemented diets had a lower (P < 0.05) malondialdehyde concentration in serum and in the studied organs but the effect was more pronounced (P < 0.05) when Se-Met was used except for the serum. These results indicated that Se-Met supplementation was more effective than SS supplementation for depositing Se in serum and tissues, enhancing the antioxidant status and reducing the drip loss of breast muscle.
