Reducing mineral element antagonism

Reducing mineral element antagonism
Inorganic trace elements are characterized by instability and ease of binding, and the possibility of interaction is easier than other substances. These effects occur between the feed, in the digestive tract tissues and cellular metabolic process between trace elements and macronutrients in the absorption and excretion, transit metabolism, function and other processes there are many antagonistic. This antagonism occurs in the digestive tract in the form of: ① simple chemical reactions between elements. Such as dietary magnesium is too much, in the digestive tract can form magnesium phosphate, thus impeding the absorption of phosphorus. ② Adsorption by colloidal particles. Such as iron and manganese have the same electronic orbitals, configuration and coordination number, can be fixed in the non-soluble magnesium salt or aluminum salt surface, so that iron and manganese absorption in the digestive tract to reduce. (iii) Ions compete for carriers in the intestinal wall. Copper and zinc are both absorbed in the small intestine, and they can compete with each other for binding sites in the metallothionein or intestinal mucosa, leading to mutual absorption inhibition. The absorption of organic trace elements in the animal organism is different from that of inorganic salts. Amino acid and protein chelates utilize the absorption

mechanism of peptides and amino acids, and are absorbed in the form of amino acids or peptides. Therefore, there is no mutual antagonism, thus the dosage is more controllable and reasonable.
Avoiding antagonism with anti-nutritional factors in feeds
Inorganic trace elements can combine with fiber and phytic acid to form a stable structure in animal intestines, for example, neutral detergent fiber (NDF) can combine with divalent iron to affect absorption; phytic acid can combine with divalent copper, iron and zinc to produce precipitation, thus reducing absorption; while metal ions in organic trace elements are located in the center of chelates, and after combining with ligands through ligands and covalent bonds, their intramolecular charge tends to be neutral, forming a stable structure, which will not be absorbed by dietary fiber. After combining with the ligand through ligand and covalent bonding, its intramolecular charge tends to be neutral, forming a stable structure, which will not be combined with anti-nutritional factors in the diet and affect absorption.

Stronger antioxidant and immunity-enhancing ability
In recent years, a large number of studies have shown that organic trace elements are superior to inorganic salt trace elements in improving immune function, improving intestinal health and reducing stress. It can enhance the body’s ability to resist pain, maximize the body’s immune response, promote cellular immunity and humoral immunity, and play the role of anti-stress and anti-disease.
Stable chemical properties
Inorganic salt molecules, anions and cations through electrostatic formation of insufficiently stable ionic bonds, so it is very easy to have chemical reactions with other substances, the chemical structure is extremely unstable; while the organic trace to trace element ions as the center of the amino acid oxygen and nitrogen atoms wrapped in the outside of the trace element, the trace element closed, which makes it has a more stable chemical properties, but also to make the molecule within the charge tends to be neutral, in the The body can effectively protect the metal ions, so that the metal ions avoid adverse reactions with substances such as gastric acid in the gastrointestinal tract and other ingredients in the diet. In particular, amino acid chelates are bonded by ligand covalent bonds and are more stable than complexes bonded by ionic bonds.

Conclusion
Micronutrients are essential nutrients for dairy cows, and both excesses and deficiencies can have adverse effects on the organism. Compared with inorganic trace elements, organic trace elements can increase the feed intake of dairy cows, improve the growth rate and fertility, improve the quality of products and body immunity, antioxidant function, reduce stress, etc. Its better safety and stability can effectively avoid the destruction of other nutrients by trace elements, reduce the antagonism of trace elements, and improve the efficiency of the utilization of trace elements and the safety of farming.
