Selenium, thiobarbituric acid reactive substances, and thyroid hormone activation in broilers supplemented with selenium as selenized yeast or sodium selenite.
The objective of this experiment was to compare the efficiencies of sodium selenite (SS) and selenized yeast (SY) supplemented at different doses (0.05 and 0.30 mg Se/kg feed) with respect to plasma glutathione peroxidase (Gpx) activity, extent of oxidative lipid injury, and thyroid hormone activation in broilers during the first four weeks of growth. Results indicate a significant increase in ...
متن کاملDetermination of Proteinaceous Selenocysteine in Selenized Yeast
A method for the quantitation of proteinaceous selenocysteine (SeCys) in Se-rich yeast was developed. The method is based on the reduction of the Se-Se and S-Se bridges with dithiotretiol, derivatization with iodoacetamide (carbamidomethylation), followed by HPLC-ICP MS. The chromatographic conditions were optimized for the total recovery of the proteinaceous selenocysteine, the minimum number ...
متن کاملEffects of Dietary Supplementation of Sodium Selenite and Selenized Yeast on Selected Qualitative Parameters of Laying Hens Eggs
In this experiment the effects of supplementation of the diet of laying hens with sodium selenite (SS) or selenized yeast (SY) on quality of eggs were studied. The chickens of Shaver Starcross hybrid were randomly divided at the day of hatching into 4 groups (n=12 in each group). The birds were fed from Day 1 of life till 9 months of age with diets differing in amounts and/or forms of selenium....
متن کاملPerformance and Egg Quality of Laying Hens Fed Diets Supplemented with Herbal Extracts and Flaxseed
In this experiment, the effects of fennel and thyme extracts with and without flaxseed were investigated on performance and egg quality of Leghorn-type laying hens (Hy-Line W-36). 200 laying hens from 26 to 38 weeks of age were assigned to five dietary treatments with five replications. The treatment groups were: 1) Control (a diet without any additives); 2) control diet plus fennel (40 mg/kg f...
متن کاملMetabolic and bioprocess engineering for production of selenized yeast with increased content of seleno-methylselenocysteine.
Specific Se-metabolites have been recognized to be the main elements responsible for beneficial effects of Se-enriched diet, and Se-methylselenocysteine (SeMCys) is thought to be among the most effective ones. Here we show that an engineered Saccharomyces cerevisiae strain, expressing a codon optimized heterologous selenocysteine methyltransferase and endowed with high intracellular levels of S...
