DCP vs MCP vs MDCP: How to Choose a Feed Phosphate

Feed phosphates supply the phosphorus (and calcium) that livestock, poultry and aquaculture cannot get from plant ingredients alone. The three standard choices — DCP, MCP and MDCP — differ mainly in phosphorus content and solubility. This guide explains how to choose.

The Basic Difference

DCP (dicalcium phosphate, CaHPO₄) typically contains about 16.5–18% phosphorus and is the long-standing standard feed phosphate. MCP (monocalcium phosphate, Ca(H₂PO₄)₂) contains about 22–23% phosphorus with a high share of water-soluble phosphorus. MDCP (mono-dicalcium phosphate) is a combination of the two, at about 21% phosphorus — between DCP and MCP in both content and behavior.

Solubility and Animal Fit

Water-soluble phosphorus is absorbed more readily by poultry, pigs and aquatic animals, which is why MCP and MDCP are often preferred in poultry, piglet and aqua feeds. Ruminants (cattle, sheep) use DCP efficiently, making DCP the economical standard for ruminant rations. TCP (tricalcium phosphate) is another option used in premixes where a high calcium-to-phosphorus ratio is needed.

Quality Points to Check

Whichever product you choose, check total phosphorus, calcium, and the safety limits — fluorine is the critical one (typically ≤0.18%), along with arsenic and lead. These are standard COA items for feed grade material; our feed grade catalog lists each product's typical specification.

Cost per Unit of Phosphorus

Compare prices per unit of phosphorus, not per ton: MCP costs more per ton than DCP but delivers roughly a third more phosphorus, in a more available form. The right choice is the one that meets your ration's available-phosphorus target at the lowest total cost. Tell us your species, target specification and quantity for a matched quotation.
