The importance of dietary selenium in animal nutrition and its bioavailability

Popis výsledku v původním jazyce

Selenium(Se) is an essential trace element, which plays an important role in animal's and human's nutrition required to maintain health and growth. Se is a part of the structure of at least 25 selenoproteins, including the iodothyronine deiodinases and thioredoxin reductases. It is involved in the synthesis of the thyroid hormone and influences overall body metabolism. Selenium being a component of the glutathione peroxidase enzyme also plays a key role in the antioxidant defense system of animals. Dietary requirements of Se in dairy animals depend on physiological status, endogenous Se content, Se source, and route of administration. Most of the dietary Se is absorbed through the duodenum in ruminants and also some portion through the rumen wall. Inorganic Se salts such as Na-selenate and Na-selenite have shown lower bioavailability than organic and nano-Se. Selenium deficiency has been associated with reproductive disorders such as retained placenta, abortion, early embryonic death, and infertility, together with muscular diseases (like white muscle disease and skeletal and cardiac muscle necrosis). This paper aims to provide a review on the nutritional importance of dietary Se in cattle, and the usage of its different forms in animal husbandry, its effect on bioavailability and absorption.
