Cysteamine is A component of Coenzyme A, containing active sulfhydryl and amino groups, which are used in the body of animals. Bioactive substances with important physiological effects. In order to play a better role, it is usually made into coated cysteamine and added to the feed.
What is the mechanism of action of encapsulated cysteamine?
1, increase growth hormone levels: somatostatin (SS) is a substance produced by the nervous system and gastrointestinal tract. It has a wide range of effects on the gastrointestinal system. It inhibits the secretion of hormones in the digestive tract and disrupts the ability of the small intestine to stimulate glucose, xylose and amino acids. And absorb various ions, inhibit animal growth. Cysteamine can selectively reduce the bioactivity and immune activity of central and peripheral somatostatin, increase the level of growth hormone (GH), and promote the rapid growth of animals.
2. Cysteamine encapsulation can enhance the immune function of animals, relieve the inhibitory effect of somatostatin on the body immunity, and stimulate the release of lymphokine; The amino mercaptan group in the structure of cysteamine has antioxidant and cell protective effects. Reduce the release of inflammatory cytokines and the phagocytosis of macrophages.
3, cysteamine is a small molecule containing sulfhydryl compounds, itself has a certain antioxidant effect, can clear free radicals produced by the body, improve the concentration of glutathione and superoxide dismutase in the blood.
4, cysteine can replace methionine and cystine to synthesize taurine. Taurine is an essential nutrient and cell protector that protects the integrity of cell membranes.
5, cysteamine can be involved in amino acid transport, protein metabolism, hormone and neurotransmitter synthesis, liver detoxification, antioxidant damage and protection of embryonic development.
What is the role of encapsulated cysteamine in aquaculture?
1, encapsulated cysteamine has a certain impact on the intestinal environment of aquatic animals, improving digestive function. The intestinal mucosal structure of tilapia could be improved by adding appropriate amount of coated cysteamine in the diet. It can also improve the activities of trypsin, amylase and lipase in tilapia's hepatopancreas, improve the ability of tilapia to digest nutrients, and meet the nutritional needs of the body's rapid growth.
2. Encapsulated cysteamine can promote protein deposition in fish. The encapsulated cysteamine can promote the catabolism of grass carp fat, and the released energy can be used for protein synthesis and promote growth. Encapsulated cysteamine also promotes amino acid anabolism and bone growth, converts adipose tissue into protein deposits, and improves the quality of fish.
3. Adding coated cysteamine to the feed of common carp and yellowfin bream can improve the contents of oxidation dismutase, total protein, albumin and globulin, such as relative body weight, body length, growth rate and growth performance.
