Twenty-one women, lifelong residents of Xichang County, Sichuan Province, China, an area of very low soil selenium (Se), received tablets containing either 100 μg Se daily as Se-enriched yeast (+Se) or no additional Se (-Se), throughout the last trimester of pregnancy and the first three months of lactation. Diet was...
Numerous dietary factors have been shown to influence the fatty acid profiles (FAP)
in breast milk from lactating women. However, few studies have evaluated the effect of trace
minerals on milk FAP. Consequently, the purpose of this study was to determine the effect
of selenium status on the FAP in...
Although fish are a nutritious food source, they also are the main source of methylmercury exposure in U.S. populations. This research examined the risks from methylmercury and benefits from omega-3 fatty acids and selenium from fish consumption. The first study provided the first region-specific quantitative risk/benefit analysis for nine commonly...
The gray-tailed vole (Microtus canicaudus) demonstrated a
requirement for selenium and vitamin E. Animals deficient in both
nutrients suffered from liver necrosis and an unthrifty condition
characterized by inappetence, profuse diarrhea, and swollen eyes.
Vitamin E appeared less effective than selenium as a prophylaxis
against this syndrome.
Total body weights,...
Provides an overview of the role of selenium in the diet of livestock, and discusses selenium supplementation rates and supplementation methods. Lists guidelines for assessing livestock’s selenium status and summarizes research useful to Oregon livestock producers.
Two concurrent studies were conducted to evaluate the effect
of selenium (Se) supplementation on beef cows. Trial 1 was designed
to evaluate the safety and efficacy of two intrareticular Se supplementation
delivery systems. Trial 2 was designed to evaluate the
transfer of Se across the placenta and through the colostrum...
The plasma concentrations and the dietary intakes of vitamin E
were determined in 20 elderly and ten young subjects. Five subjects
in the older group were known to take supplements of vitamin E. The
mean concentration of tocopherols (determined chemically) in the
plasma of all unsupplemented subjects was 1.12 ±...
Whole blood selenium levels were measured in 207 horses, representing 41 ranches and 11 regions throughout Oregon. Age, sex,
diet, and history of disease were recorded. Diet was divided into
three categories; local feed only, commercial feed, and Se supplemented feed. Region (p<.01), diet type (p<.01), and a region x...
