COMPOSITE SALT OF PHOSPHORIC AND AMINO ACIDS WITH POLYVALENTMETALS AND FEED ADDITIVE COMPOSITION FOR RUMINANTS

摘要

A powdery or granular feed additive composition for ruminants comprising as the active ingredient a composite salt of phosphoric and amino acids with polyvalent metals (a final composite salt) which is obtainable by treating a composite salt formed from a basic amino acid, magnesium, and orthophosphoric acid (an intermediate composite salt) either with a salt of a di- or trivalent metal other than magnesium or with a combination of the salt and either a condensed phosphoric acid ingredient alone or both the condensed ingredient and an orthophosphoric acid ingredient, and which is insoluble in neutral to alkaline water and soluble in acidic water. The final salt has a better stability in neutral to slightly acidic water, i.e., a lower solubility therein, than the intermediate salt, and combines a better insolubility of the basic amino acid in the rumina of ruminants and an excellent solubility in the digestive organs following the abomasa.
