As such, phosphorus is a key ingredient in animal feeds, namely Monocalcium Phosphate (MCP) and Dicalcium Phosphate (DCP). While only about 5% of global phosphate consumption goes toward animal feed production, the production of phosphate animal feeds plays a critical role in maintaining livestock health and overall food security.
