Selenium in poultry nutrition: a review
Selenium has been known for two centuries and its biological activities have been studied for nearly a hundred years, however the problem of Se deficit has still been persisting both in humans and animals. The cause of Se deficit in animals may be low Se level in soil. This mainly applies to cattle and sheep with their direct link to soil via roughage. The risk of Se deficit in pigs and poultry...
متن کاملTrace mineral changes in response to organic and inorganic selenium supplementation
Twenty-one Lori–Bakhtiary sheep were randomly allocated into 3 groups to compare the effects of oral selenium nano particles (Se NPs) and sodium selenite (Na-Se) supplementation on serum selenium, copper, zinc, molybdenum, manganese and cobalt concentration. Groups 1 and 2 orally received Se NPs and Na-Se (1 mg/kg) for 10 consecutive days, respectively ...
متن کاملOrganic and inorganic selenium: I. Oral bioavailability in ewes.
Although the essentiality of dietary Se for sheep has been known for decades, the chemical source and Se dosage for optimal health remain unclear. In the United States, the Food and Drug Administration (FDA) regulates Se supplementation, regardless of the source of Se, at 0.3 mg of Se/kg of diet (as fed), which is equivalent to 0.7 mg of Se/d or 4.9 mg of Se/wk per sheep. The objectives of this...
متن کاملInfluence of Inorganic and Organic Selenium Sources on Broiler Performance and Meat Quality
An experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (Se) sources on broiler male birds (Ross 308). Uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental Se, negative control), 0.25 ppm of inorganic Se, 0.5 ppm of inorganic Se, 0.25 ppm of inorganic Se + 0.25 ppm of organic ...
متن کاملSelenium as a photoabsorber for inorganic-organic hybrid solar cells.
As an inorganic photoabsorber, selenium was used in a mesoscopic solar cell with a hybrid organic-inorganic structure of TiO2/Se/P3HT/PEDOT:PSS/Ag, in which the Se layer was prepared by vacuum thermal deposition and post thermal treatment. The microstructure, photoelectrical properties, as well as the rationality in structural design of the solar cell were illustrated in detail. Finally, the hy...
