A PHOSPHORIC ACID/LYSINE/MAGNESIUM COMPOSITE SALT AND ITS USE AS AN ANIMAL FEED ADDITIVE

摘要

Subject A process for producing a phosphoric acid/lysine/magnesium salt which is excellent in slurry properties and which can industrially be produced. Means for Solution Lysine, phosphoric acid and magnesium hydroxide or magnesium oxide are added simultaneously to a slurry containing a desired phosphoric acid/lysine/magnesium composite salt while the slurry temperature is maintained at 50 C or higher and the pH constantly in an alkaline region respectively, whereby spherical aggregate crystals are formed which were not obtained by the conventional process. Since the aggregate crystals having the uniform shape and size are formed, the slurry properties are markedly improved.
