Selenium status in adult cats and dogs fed high levels of dietary inorganic and organic selenium.
Cats (Felis catus) maintain greater blood Se concentrations compared with dogs (Canis familiaris) and, unlike dogs, show no signs of chronic Se toxicity (selenosis) when fed dietary organic Se (selenomethionine) concentrations of 10 μg/g DM. This study investigated the response of cats and dogs to high dietary concentrations of sodium selenite and organic Se to determine differences in metaboli...
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 کاملEffect of organic and inorganic selenium sources and levels on sow colostrum and milk selenium content.
A study was conducted to evaluate the short-term effects of feeding two dietary Se sources at various Se levels on the transfer of Se to the dam's milk and nursing pig. Six dietary treatments were arranged in a 2 x 2 factorial arrangement with two additional treatments in a randomized complete block designed experiment. Inorganic (sodium selenite) or organic (Se-enriched yeast) Se sources were ...
متن کاملDistribution of selenium in zebrafish larvae after exposure to organic and inorganic selenium forms.
Selenium is an essential micronutrient for many organisms, and in vertebrates has a variety of roles associated with protection from reactive oxygen species. Over the past two decades there have been conflicting reports upon human health benefits and detriments arising from consumption of selenium dietary supplements. Thus, early studies report a decrease in the incidence of certain types of ca...
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...
