Compared with the prior art, the present invention has the following beneficial effects:

Arginine (Arginine, Arg) is a component with important physiological functions in the ornithine cycle. It mainly plays the role of immune regulation and immune defense through the two metabolic pathways of "arginase" and "NO". In the NO pathway, M1 macrophages secrete pro-inflammatory factors to induce an increase in the expression of inducible nitric oxide synthase (iNOS), Arg generates citrulline and NO under the action of iNOS, and NO regulates T cells, Macrophage activity and NK cell activity, inhibit antibody response and mast cell response ability, and play an important role in the body's defense against intracellular pathogen infection. Arginase I (Argina_se I) secreted by M2 giant cells decomposes Arg It is urea and ornithine, promotes cell division and collagen formation, performs cell regeneration and wound repair on tissue damage caused by inflammation, and at the same time generates polyamines, thereby regulating the function of macrophages.

Moreover, arginine is the precursor of NO, polyamines and glutamine, which can be catalyzed by NOS to generate biologically active NO in animals, and NO can activate focal adhesion kinase (FAK) on the intestinal mucosa, while Proteins such as talin and actin on the mucosa can be activated by FAK, and then participate in the migration of epithelial cells, form new epithelial cells, promote mucosal repair, increase the villi height and crypt depth of the duodenum, jejunum and ileum, Significantly increased the number of goblet cells in the jejunum and ileum.

Tryptophan (Trp) is the only amino acid in animals that binds to serum proteins through non-covalent bonds. It is widely involved in the synthesis of proteins and nucleic acids. Two metabolic pathways of acid (kynurenine, Kyn) and 5-hydroxytryptamine (5-hydroxytry-ptamine, 5-HT): the rate-limiting enzyme of the Kyn pathway --- indole 2,3--dioxygenase (indoleamine 2,3-dioxygenase, IDO) plays an important role in the immune function of Trp. Threonine is the second or third limiting amino acid in pigs or poultry, and plays an important role in maintaining animal intestinal morphology, mucus secretion, brush border enzyme activity and growth performance.

The antioxidant activity of curcumin can effectively reduce or eliminate the damage caused by free radicals, protect liver cells damaged by H ₂ O ₂ oxidative stress, and enhance the total antioxidant capacity of cells, and its metal complexes are effective against O ₂ and OH All have obvious clearing effect.

Sodium butyrate can promote animal growth, improve feed conversion rate, improve animal intestinal microflora, adjust the ecological balance of animal intestinal flora, and significantly increase the number of mast cells, intraepithelial lymphocytes and goblet cells in the small intestine of broilers. Thereby improving the body's immunity.

No antibiotics are added to this premixed feed, but it is rich in minerals, various vitamins, various amino acids and functional green additives. It mainly increases the immunity of broilers by adding tryptophan and arginine, which can effectively improve The resistance of broiler chickens to viruses reduces the occurrence of diseases. At the same time, threonine, curcumin, sodium butyrate and arginine are added to regulate intestinal flora and improve intestinal health.
