Title: Calcium phosphate and calciumchlorophosphate compositions

Abstract: Novel feed grade calcium phosphate compositions are provided which contain calcium chlorophosphate in varying amounts. This novel composition and other heretofore known varieties of feed grade calcium phosphates are prepared by low temperature drying steps (spray drying or crystallization-evaporation) of solutions or slurries which have been partially defluorinated to the extent that the solution P/F ratio is at least 30-35 but less than 100. The novel compositions described above have adequate levels of phosphorus availability to animals thereby permitting their usage as an animal feed supplement.
