Product Application
This product is feed nutrition fortifier.Livestock and poultry lack methionine, will cause dysplasia, weight loss, liver and kidney function weakened, muscle atrophy, fur metamorphism.Adding 1kg methionine to the feed is equivalent to the nutritional value of 50kg fish meal.The general additive amount in feed is 0,05%-0.2%.
Commercial methionine content ≥98.5%, is one of the essential amino acids for the growth of livestock, is the "skeleton" amino acid of biosynthesis protein, has a strong regulatory effect on the metabolism of animals, widely used in the fields of medicine, food, feed and cosmetics.In medicine, it can be used as the main component of amino acid infusion and compound amino acid, and can also be used to synthesize medicinal vitamins.In food, for food amino acid fortification and food health products processing, can be used as nutritional supplements, because of the special smell, it is only used for fish cake products;In the feed industry, methionine has the largest amount, which is used as the nutrient fortifier of the feed and the feed additive to make up the balance of amino acids. Among the varieties of nutritional feed additives of amino acids, methionine accounts for 60%, lysine accounts for 30%, and other amino acids account for about 10%.
