Selenium in Ruminant Nutrition: A Review
TL;DR: The current nutritional status of ruminant animals in many geographical areas and involving various feeding programs with this element has not been established, and the recent widespread deficiency problems with nonruminants suggest that such an assessment should be made.

TL;DR: The interface between nutritional science and reproductive physiology provides considerable potential for optimizing reproductive efficiency in dairy cattle and it attempts to provide a basis for further investigation of specific mechanisms by which reproductive function is affected.

TL;DR: A negative effect of statin on selenoprotein synthesis does seem to explain many of the enigmatic effects and side-effects of statins, in particular, statin-induced myopathy.

TL;DR: Nine well-managed dairy herds were monitored for 1 yr to determine if bulk tank SCC and rate of clinical mastitis were associated with dietary and plasma Se and vitamin E status, confirming earlier findings that Se anditamin E status of dairy cows are related to mammary gland health.

TL;DR: The relationships between foetus Se metabolism and pregnant dam Se status are critical for productivity and need further research.
187 citations
TL;DR: Gene knock-out studies of selenoproteins revealed that their absence during spermatogenesis results in abnormal spermatozoa, which in turn affects semen quality and fertility and should be in optimal quantity to maintain reproductive function in males and to avoid infertility.

Cites background from "Selenium in Ruminant Nutrition: A R..."
...Ruminants generally require Se at 0.1 mg/kg (Ammermann and Miller, 1975; James et al., 1991), poultry at 0.05–0.15 mg/kg (NRC, 1994), and swine at 0.1–0.3 mg/kg of ration (NRC, 1998; Polish Norm of Pigs Nutrition, 1993)....

TL;DR: When hemolyzates from erythrocytes of selenium-deficient rats were incubated in vitro in the presence of ascorbate or H2O2, added glutathione failed to protect the hemoglobin from oxidative damage.
Abstract: When hemolyzates from erythrocytes of selenium-deficient rats were incubated in vitro in the presence of ascorbate or H(2)O(2), added glutathione failed to protect the hemoglobin from oxidative damage. This occurred because the erythrocytes were practically devoid of glutathione-peroxidase activity. Extensively purified preparations of glutathione peroxidase contained a large part of the (75)Se of erythrocytes labeled in vivo. Many of the nutritional effects of selenium can be explained by its role in glutathione peroxidase.
