Vitamin E and selenium plasma concentrations in weanling pigs under field conditions in Norwegian pig herds

Abstract

Background: The status of α-tocopherol (vit E) and selenium (Se) has been shown to influence disease resistance in pigs, and may be important for the health of weanling pigs.Methods: Plasma levels of both vit E and Se were followed in weanling pigs under field conditions in six Norwegian pig herds. Plasma vit E and Se were measured in 3 sows from each herd and 4 piglets in the litter of each sow at the day before weaning (day -1); and in the same piglets at days 4, 8 and 18 after weaning.Results: Mean plasma vit E was 4.0 µg/ml in the sows and 2.6 µg/ml in the piglets at day -1, fell to 1.6 µg/ml in the weanling pigs at day 4, and remained low. Mean plasma Se was 0.22 µg/g in the sows and 0.08 µg/g in the piglets at day -1, rose to 0.10 µg/g in the weanlings at day 4, and continued rising. Conclusion:The results suggest that vit E and Se supplementation to piglets and weanling pigs in Norway may still be suboptimal, but that levels of the two nutrients partially compensate for each other in the weaning period.

Selenium Distribution in Camel Blood and Organs After Different Level of Dietary Selenium Supplementation

“…However, in most of the case, the correlation coefficients were higher than our result. The lack of correlation between Se and vitamin E was also observed in pig [29] and calf [30].…”

“…The blood sampling was carried out weekly in the morning before feed distribution at days1, 8,15,22,29,36,43,50,57, and 64.…”

Effect of Different Selenium Supplementation Levels on Selenium Status in Camel

“…There was a slight negative effect of Se supplementation on vitamin E concentration in plasma, with a negative correlation between GSH-Px and vitamin E. In pig, a lack of correlation was observed between Se concentration in serum and vitamin E concentration in plasma, and no effect of dietary selenium was reported [26].…”

“…In our study, the relationship was highly significant, but the correlation coefficient was lower than those reported by Corbera et al [14], Abdel Rahim [18], and Bengoumi et al [10]: 0.88, 0.88, and 0.94, respectively. No data on correlation between Se and vitamin E were available in camel, but a similar lack of correlation was observed in other species [26,27].…”

Vitamin E and omega-3 fatty acids independently attenuate plasma concentrations of proinflammatory cytokines and prostaglandin E2 in Escherichia coli lipopolysaccharide-challenged growing–finishing pigs1

“…However, recent evidence suggests that dietary levels of Vit E found in commercial pig diets are suboptimal and may limit adequate immune function (Sivertsen et al, 2007;Lauridsen et al, 2011). Omega-3 fatty acids are known to competitively reduce PGE 2 biosynthesis under immune system stimulation by reducing availability of enzymes required for the conversion of omega-6 fatty acids to arachidonic acid, which is a precursor for PGE 2 production (Wall et al, 2010).…”
