Effect of Different Selenium Sources on Productive Performance, Serum and Milk Se Concentrations, and Antioxidant Status of Sows

Abstract

The experiment was conducted to study the effects of different selenium (Se) sources on productive performance, serum and milk Se concentrations, and antioxidant status of sows. A total of 12 sows (Landrace×Yorkshire) with same pregnancy were randomly divided into two groups; each group was replicated six times. These two groups received the same basal gestation and lactation diets containing 0.042 mg Se/kg, supplemented with 0.3 mg Se/kg sodium selenite or selenomethionine (i.e., seneno-DL: -methylseleno), respectively. The feeding trial lasted for 60 days, with 32 and 28 days for gestation and lactation period, respectively. Compared with sodium selenite, maternal selenomethionine intake significantly increased (P < 0.05) the weaning litter weight and average weight of piglet. The Se concentration in the serum, colostrum, and milk of sows were significantly higher (p < 0.05) in the selenomethionine-treated group. The antioxidant status was greatly improved in sows of selenomethionine-treated group and was illuminated by the increased total antioxidant capability (T-AOC; P < 0.05) and decreased malondialdehyde (MDA; P < 0.01) level in the serum of sows, increased T-AOC (P < 0.05), glutathione (GSH) peroxidase (P < 0.05), superoxide dismutase (P < 0.05) and GSH (P < 0.05), and MDA (P < 0.05) level in the colostrum and milk of sows. These results suggested that maternal selenomethionine intake improved Se concentration and antioxidant status of sows, thus maintain maternal health and increase productive performance after Se was transferred to its offspring.

“…The effect of Se sources addition on plasma total Se concentration appeared dose dependent when organic forms (SY or SO) were supplied, whereas the inorganic form (SS) to provide beyond 0.1 mg/kg of feed failed to increase plasma Se level. Mahan et al (1999) also reported that 0.05 mg/kg supplemental Se from SS allowed plasma Se increase, but that plasmatic Se concentration elevation was greater when the organic Se source was provided (Hu et al, 2011;Zhan et al, 2011).…”

Effects of Inulin Supplementation in Low‐ or High‐Fat Diets on Reproductive Performance of Sows and Antioxidant Defence Capacity in Sows and Offspring

“…The serum T‐AOC was assayed by the reduction in Fe 3+ ‐tripyridyltriazine to Fe 2+ ‐ tripyridyltriazine and expressed as U/ml according to the method of Hu et al. (). The serum CAT activity was measured by analysing the rate at which it caused the decomposition of H 2 O 2 at 240 nm as reported by Zhang et al.…”

“…The serum MDA concentration was measured by reaction with thiobarbituric acid at 95°C and expressed as nmol/ml as previously described by Shen et al (2015). The serum T-AOC was assayed by the reduction in Fe 3+ -tripyridyltriazine to Fe 2+ -tripyridyltriazine and expressed as U/ml according to the method of Hu et al (2011). The serum CAT activity was measured by analysing the rate at which it caused the decomposition of H 2 O 2 at 240 nm as reported by Zhang et al (2014), and was expressed as U/ml for CAT activity.…”

“…The MDA concentration in plasma and milk was measured by reaction with thiobarbituric acid at 95 °C and expressed as nmol/ml as previously described by Grotto et al [21]. The T-AOC in plasma and milk were assayed by the reduction of Fe 3+ -tripyridyltriazine to Fe 2+ -tripyridyltriazine and expressed as U/ml according to the method of Hu et al [22]. The measurement of GSH-Px activity of plasma and milk was based on the oxidation of NADPH and expressed as U/ml in accordance with the method of Hernández et al [23].…”
