Abstract
QUISIRUMBAY-GAIBOR, Jimmy and VILCHEZ PERALES, Carlos. Selenium and glutathione peroxidase in swine nutrition. Ces. Med. Vet. Zootec. [online]. 2019, vol.14, n.1, pp.57-69. ISSN 1900-9607. https://doi.org/10.21615/cesmvz.14.1.5.
Selenium (Se) is a mineral that fulfills important functions in the organism, one of which is to favor oxidative balance by being part of the enzyme glutathione peroxidase. There are two sources of Se that can through the diet be supplemented to animals, organic and inorganic. The oldest form of It has been the inorganic usually the sodium selenite and the organic is the Se-methionine which is the main component of the Se-yeast and recently the hydroxylated form known as 2-hydroxy-4-methyl acid-butane butane. The administration of Se-organic presents higher levels of retention in the organism, higher tissue concentration in the liver, muscle, serum and greater transfer to newborn piglets through colostrum and milk. In pigs in stages of completion it has been shown to reduce drip losses by favoring water retention. The most recommended levels of selenium in swine nutrition are between 0.15 and 0.3 ppm and as a Se-organic source of choice.
