Comparative study of a new organic selenium source v. seleno-yeast and mineral selenium sources on muscle selenium enrichment and selenium digestibility in broiler chickens.
Two experiments were conducted on broiler chickens to compare the effect of a new organic Se source, 2-hydroxy-4-methylselenobutanoic acid (HMSeBA; SO), with two practical Se additives, sodium selenite (SS) and Se yeast (SY). The relative bioavailability of the different Se sources was compared on muscle (pectoralis major) total Se, selenomethionine (SeMet) and selenocysteine (SeCys) concentrat...
متن کاملOptimization of soluble organic selenium accumulation during fermentation of Flammulina velutipes mycelia.
Selenium is an essential nutrient with diverse physiological functions, and soluble organic selenium (SOS) sources have a higher bioavailability than inorganic selenium sources. Based on the response surface methodology and central composite design, this study presents the optimal medium components for SOS accumulation in batch cultures of Flammulina velutipes, i.e. 30 g/L glucose, 11.2 mg/L so...
متن کاملSelenium Enrichment of Horticultural Crops.
The ability of some crops to accumulate selenium (Se) is crucial for human nutrition and health. Selenium has been identified as a cofactor of the enzyme glutathione peroxidase, which is a catalyzer in the reduction of peroxides that can damage cells and tissues, and can act as an antioxidant. Plants are the first link in the food chain, which ends with humans. Increasing the Se quantity in pla...
متن کاملComparing ORGANIC SELENIUM sources
wide range of products is available; from inorganic, sodium selenite or selenate coated or not, even nanoparticles to organic forms such as selenized yeasts, chelates of selenium methionine (SeMet), pure forms of SeMet or hydroxy-selenomethionine, and some complexes sources of Se based on mixing mineral Se with glycinates, proteinates, etc. It has been confirmed that, comparing with mineral sel...
متن کاملeffect of various types and levels of organic selenium on poultry production, egg quality and selenium enrichment of eggs
a eight-week trial was carried out to investigate the effects of various levels and type of organic selenium as compared to inorganic selenium. total of 81 layer hens (lsl) 35 weeks of age were used in a randomized complete blocks with 9 treatments, 3 replications of 3 birds per experimental unit. treatment diets included control 0/3 mg/kg sodium selenite and selenium yeast, (250 mg/kg, 500 mg/...
