Effects of Dietary Nano-Selenium on Tissue Selenium Deposition, Antioxidant Status and Immune Functions in Layer Chicks

Effects of organic, inorganic, and nano-Se on growth performance, antioxidant capacity, cellular and humoral immune responses in broiler chickens exposed to oxidative stress

“…Mohapatra et al, (2014) supplemented nano-Se and inorganic Se in layer chicks up to 8 weeks. The results showed that antibody titers against SRBC, immunization CBH response, gluthation peroxidase activity and superoxidase dismutase of layer chickens were significantly higher in groups with different amounts of nano-Se compared to control group and group with sodium selenite.…”

“…Puvadolpirod and Thaxton (2000) used ACTH (Adrenocorticotropic hormone) to induce oxidative stress in broiler chickens which decreased relative weights of the major immunobiological organs (i.e., spleen, thymus, and bursa) and increased liver weight (Cai et al, 2012). Mohapatra et al (2014) indicated that the range between optimal and toxic dietary levels of nano-Se was more than that of sodium selenite. Zhang et al (2001) demonstrated that bioavailability of nano-Se was higher than that of inorganic forms (sodium selenite).…”

Antioxidant status of rats’ blood and liver affected by sodium selenite and selenium nanoparticles

“…Howeover, the biological nature of this reaction is not known yet (Chen et al 2016b). In an organic form, selenium is used as a component of amino acids (e.g., selenomethionine) (Horky et al 2013;Mohapatra et al 2014). Selenium in a low dose is an essential element important in several physiological processes, such as synthesis of selenocysteine, coenzyme Q, glutathione peroxidase and thioredoxin reductase.…”

“…Thus, alternative nanotechnological solutions are searched instead of conventional alternatives as nanoparticles show new promising properties, which could supress toxicity with maintaining the positive effects of selenium on an organism (Arruda et al 2015;Fernandez-Llamosas et al 2016;Mohapatra et al 2014;Skalickova et al 2017). The synthesis and application of selenium nanoparticles (SeNPs) attracted increased attention due to several benefits, such as low toxicity, biocompatibility and chemical stability (Zhang et al 2001).…”

FINCTIONAL EGG PRODUCTION. II. THE ROLES OF SELENIUM, ZINC, AND IODINE (review)

“…Organic preparations of Se diacetophenonyl selenide, or bis-(benzoylmethyl)-selenide (DAFS-25), and 9-phenyl-sym octahydro selenoxanthene (selenopyran) have been developed and are being used in Russia. Se nanopreparations ensure more precise delivery of the element to the target organs and tissues and have a low toxicity, which increases the bioavailability and effectiveness of Se application [27][28][29].…”
