Feed additive – sodium humate
The structure of sodium humate is relatively complicated. The humic acid molecule contains a benzene ring, a fused ring and some heterocyclic rings (such as pyrrole, furan, anthracene, etc.), and each aromatic ring has a bridge bond and various functions on the aromatic ring. The group is mainly a carboxyl group, a phenol group, a hydroxyl group, a methoxy group, a thiol group or the like. The content of humic acid dry base in sodium humate is more than 75%, which was originally produced as a farm animal companion. It is a good veterinary drug and feed additive for the production of green milk and egg food.
The main elemental composition of sodium humate is carbon, hydrogen, oxygen, nitrogen, sulfur, and is a polycondensate of a polyvalent phenolic aromatic compound and a nitrogen compound. The molecular weight distribution is wide, the molecular weight of small molecules is tens of thousands, and the molecular weight of macromolecules is tens of thousands to millions.
The structure is also quite complicated, and contains various functional groups such as phenolic hydroxyl group, hydroxyl group, alcoholic hydroxyl group, hydrazine hydroxyl group, enol group, sulfonic acid group, amine group, free sulfhydryl group, sulfhydryl group, decyloxy group, methoxy group and the like. . Each composition is entangled by chemical and physical interactions such as bonding, hydrogen bonding, and adsorption. Due to the presence of these reactive groups, the acidity, hydrophilicity, ion exchangeability, complexation and high adsorption capacity, buffering and catalytic ability of humic acid are determined.
The addition of sodium humate to the feed can effectively adsorb various toxic and harmful substances produced by the feed, and can also absorb toxic substances produced by digestion and metabolism during digestion and metabolism. Such as: amines, hydrogen sulfide and other substances, maintaining the normal microflora of the intestines.
Sodium humate is added to the feed and can also act as a drug, which has a significant therapeutic effect on intestinal ulcers and gastritis. Because sodium humate contains small molecules of fulvic acid, it can adhere to the surface of the ulcer, which can quickly stop bleeding and facilitate rapid healing of the tissue. Sodium humate has an immune-enhancing effect on animals, and promotes antigenic substance uptake, cellular immunity and humoral immunity in the immune process.
Sodium humate contains sulfhydryl groups to participate in the body’s redox reaction, maintain strong metabolism, and promote cell proliferation. Sodium humate can also act on the autonomic nervous system, inhibiting the stimulation of sympathetic nerves, making animals quiet and reducing consumption.
Because sodium humate is an organic acid, it can regulate the pH value of digestive tract, promote the secretion of digestive enzymes in young animals, activate the activity of various enzymes in the body, change the permeability of cell membrane, improve the absorption of feed nutrients, and improve The utilization rate of feed promotes growth and development. For biochemical fulvic acid, it not only contains humic acid, but also contains a certain amount of nucleic acid, amino acid, VB, VC, inositol, polysaccharide, in addition to having strong biological activity, it is also an important nutrient for animals.
According to clinical evidence, sodium humate has hemostasis, anti-inflammatory, analgesic, astringent, adsorption, anti-allergic, secretory secretion, regulating gastrointestinal function, improving immunity and enhancing animal disease resistance. At present, some feed manufacturers, in order to cater to the consumer psychology of the farmers, improve the growth of animals, the pursuit of feed effects, the addition of a large number of antibiotics in the feed, due to the residues of antibiotics, directly affect people’s health.
As a green product, sodium humate can be added to feed to replace antibiotics. Scientific research in recent years has shown that sodium humate, as a new type of feed additive, has a peculiar effect and plays a very important role in aquaculture, and will certainly promote the development of the feed industry.
