Dicalcium Phosphate （DCP）, chemical formula is CaHPO4·2H2O, It is a poultry and livestock feed additive rich in phosphorus and calcium. Because its phosphorus-calcium ratio (1:1.29) is closest to the phosphorus-calcium ratio in animal bones and it can be completely dissolved in animal gastric acid, it can easily enter the animal body to participate in its metabolism, forming important life substances such as hormones, enzymes and vitamins required by the animal body, maintaining the phosphorus-calcium ratio in bones, promoting the rapid growth of the animal body and preventing various diseases caused by phosphorus and calcium deficiency. Feed-grade DCP is currently recognized as one of the best feed mineral additives at home and abroad.
