Abstract

A P-type forage additive is an anionic exchange resin containing exchangeable radical of phosphoric acid. It is prepared through anionic exchange between phosphoric acid radicals and anionic exchange resin to carry the phosphoric acid radical by anionic exchange resin.

Description

technical field [0001] The invention relates to a phosphorus source feed additive based on anion exchange resin and a preparation method thereof. Background technique [0002] Phosphorus is one of the most abundant mineral elements in animals, its requirement is second only to calcium, and plays an important role in the growth and development of animals. Among them, phosphorus accounting for 85-88% of total phosphorus exists in bones and teeth, and maintains the normal hardness of bones and teeth together with calcium. Moreover, phosphorus is also used as a component of high-energy phosphate bonds and phosphocreatine to participate in the energy metabolism of the body. Phosphorus participates in the absorption of lipids and fat-soluble vitamins and the formation of cell membranes in the form of phospholipids, and is used as a component of genetic material and some enzymes. Components involved in many important life processes of the body. The lack or deficiency of phosphoru...
