Physiological Functions of Selenium
Selenium is inserted into selenocysteine in the form of selenophosphate in the body, and then synthesized into selenoproteins, which exert biological functions through selenoprotein.
Selenium mainly exists in organisms in the form of selenocysteine and selenomethionine.
Selenium Deficiency
Cause diseases such as degeneration and necrosis of animal organs and tissues. The symptoms are as follows:
Hepatodystrophy in pigs
Mulberry heart disease in piglets
Encephalomalacia or exudative diathesis of chicken
Nutritional muscle degeneration of duck
Retention of the placenta of cattle and goat/sheep
White muscle disease of calf and lamb
Sawdust liver of cattle
Selenium Deficiency - Selenium from Three Different Sources
Selenite/Selenate
Selenite/Selenate
Mineral source
First licensed supplementation in 1979
Only prevent selenium deficiency
Low cost
0% Selenium is from selenomethionine

Generation: Se-Yeast
Organic selenium source, produced by fermentation
Since 2006, there have been
many brands on the market, but their quality
varied significantly
Selenium methionine accounts for about 60%
60% Selenium is from selenomethionine
Synthetic Selenomethionine
Generation: OH-SeMet
Organic selenium source, chemical synthesis

Application Effects of Selenomethionine
Improve the Growth Performance of Animals
Improve Antioxidant Capacity and Enhance Immunity
Supplementing different selenium sources can effectively increase the content of GSH-Px in serum, muscles and liver
Supplementing different selenium sources can effectively improve the content of T-AOC in serum and muscles
Supplementing different selenium sources can effectively reduce the content of MDA in muscles and liver
The effect of Se-Met is better than that of inorganic selenium sources
Reproductive Performance
Preproductive Performance - Dam
Supplementing an appropriate amount of Se-Met can not only promote the secretion of reproductive hormones in dams, but also increase the weaning litter weight and daily gain of young animals.
Improve Meat Quality
Supplementing the diet for growing-finishing pigs with0.3-0.7 mg/kg SM can improve meat color, reduce cooking loss, and increase meat pH and carcass yield, and 0.4 mg/kg is the optimal addition level.
Improve Selenium Deposition
Compared with sodium selenite and Se-yeast, dietary supplementation of Se-Met can increase the content of selenium in liver, kidneys and muscles, produce selenium-enriched meat, and reduce MDA in longissimus dorsi.
Egg Quality
A total of 330 ISA brown layers were divided into three groups: control group, 0.3 mg/kg sodium selenite group, and 0.3 mg/kg Se-Met group. The content of selenium in eggs was analyzed. The results are as follows:
Milk Quality - Selenium Deposition
Se-Met can effectively pass through the breast barrier to form milk, and the selenium deposition efficiency in milk is significantly higher than that of sodium selenite and Se-yeast, which is 20-30% higher than that of Se-yeast.
Application Solutions of Sustar's Selenomethionine
Recommended application solutions (take 0.2% L-selenomethionine, for example)
1. Supplementing 60 g/t L-selenomethionine to replace 100 g/t Se-yeast directly;
2. If the total inorganic selenium in the diet is 0.3 ppm: inorganic selenium 0.1 ppm + L-selenomethionine 0.1 ppm (50 g);
3. If the total inorganic selenium in the diet is 0.3 ppm: L-selenomethionine 0.15 ppm (75 g) is completely substituted;
4. Produce selenium-enriched products:
Basal inorganic selenium 0.1-0.2 ppm + L-selenomethionine 0.2 ppm (100 g) can make the selenium content in meat and eggs reach 0.3-0.5 ppm, forming a selenium-enriched food;
Supplementing L-selenomethionine 0.2 ppm (100 g) alone can meet the requirements of selenium-enriched meat and egg food (≥0.3 ppm).
The livestock and poultry formula feed or aquafeed can be supplemented with 0.2-0.4 mg/kg (based on Se); the formula feed can also be directly supplemented with 200-400 g/t of this product with a content of 0.1%; 100-200 g/t of this product with a content of 0.2%; and 10-20 g/t of this product with a content of 2%.
