“…Nevertheless, in SeSP‐supplemented rats, plasma selenium concentration was slightly lower than Se‐supplemented rats. Interestingly, several studies obtained similar results (Cases et al, 2001; Suzuki et al, 2006; Takahashi et al, 2017), while others did not evidence any difference between sodium selenite‐ and spirulina‐enriched supplementation (Falk et al, 2020; Zhang et al, 2020). When observed, the reduction of plasma selenium concentration in the SeSp group could be explained by the selenium form.…”

“…Zhan et al [16] and Hu et al [30] reported that weaned body weight and weight gain were improved when sows were fed organic Se 0.3 ppm compared with inorganic Se 0.3 ppm during late gestation and lactation. A recent study by Falk et al [31] also showed that body weight of piglets was improved by organic Se and high level of Se. The results of the present study were…”

Objective: This study was conducted to evaluate the effects of selenium (Se) source and level on the physiological response, reproductive performance, serum Se level, and milk composition in gestating sows.Methods: A total of 54 multiparous sows (Yorkshire×Landrace) with average body weight (BW), backfat thickness (BF), and parity were assigned to one of five treatments with 10 or 11 sows per treatment using a 2×2 factorial arrangement with one additional treatment in a completely randomized design. Inorganic or organic Se (IS or OS) sources were added to the diet at 0.30 ppm and 0.50 ppm Se. A non-Se-fortified corn-soybean meal basal diet served as a negative control. Treatments were as follows: i) Control: corn-soybean based diet, ii) IS30: control+inorganic Se 0.30 ppm, iii) IS50: control+inorganic Se 0.50 ppm, iv) OS30: control+ organic Se ppm, and v) OS50: control+organic Se 0.50 ppm.Results: At day 21 of lactation, piglet weight and weight gain in the OS treatments were higher than those in the IS treatments (p<0.05). Meanwhile, adding 0.5 ppm Se also resulted in the same significant differences in piglet BW and weight gain (p<0.05). Colostrum and milk Se concentrations increased (p<0.05) with Se level for both Se sources but were greater when sows were fed organic Se (p<0.05). Except for 24 hours postpartum, the Se concentrations were higher when sows were fed organic Se (p<0.05). Sow serum Se content was greater as Se levels increased from 0.3 ppm to 0.5 ppm at day 110 of gestation, 24 hours postpartum and day 21 of lactation (p<0.05). The pig serum Se concentration increased as the dietary Se level increased (p<0.05) and was higher when the sow dietary Se source was organic (p<0.05). Organic Se 0.5 ppm also had the highest serum Se level at two measured points (p<0.05).Conclusion: Consequently, supplementation with organic Se or 0.5 ppm Se in a gestating diet could improve piglet performance, the Se status of sows and piglets and milk composition, but organic Se at 0.5 ppm is optimal.

Selenium is an essential trace element for pig growth; generally, inorganic or organic selenium is used for dietary selenium supplementation. Newborn piglets obtain all nutrients from the sow; thus, the sow absorption rate of different selenium sources significantly affects sow reproductive performance and piglet development. Therefore, a meta-analysis was performed to provide insights into whether organic selenium is better than mineral selenium for improving sow reproductive performance and piglet development. The present study investigated the effects of different selenium sources in sow feed using articles published between June 1, 1980, and December 31, 2020, from four databases. In the meta-analysis, 19 articles (347 sows) from seven countries were included. It was shown that feeding organic selenium to sows during pregnancy significantly increased newborn piglet weight (P < 0.05), piglet weight at weaning (P < 0.05), litter weight at weaning (P < 0.01), selenium content in sow colostrum (P < 0.01), milk (P < 0.01) and serum (P < 0.01); and selenium content (P < 0.01) and glutathione peroxidase activity (P < 0.05) in piglet serum. However, it had no effect on the number of liveborn piglets and litter weight at birth. Owing to study heterogeneity (I 2 > 50%), we hypothesized that the sow breed or weaning age were the influencing factors. Publication bias and sensitivity analyses indicate that the present results are robust. Further research is needed to better understand how different selenium sources affect sow reproduction and piglet development.
