COMPLEX SALT OF PHOSPHORIC ACID AND AMINO ACID, MANUFACTURING PROCESS THEREOF AND AN ADITIVE COMPOSITION FOR USING INTO FODDER FOR RUMINANTS

摘要

A novel phosphoric acid-amino acid complex salt is provided which manifests insolubility in a neutral or alkaline aqueous solution and solubility in an acidic aqueous solution and has a basic amino acid, an alkaline earth metal, and phosphoric acid as main components thereof. An additive composition containing the complex salt and used in a feed for ruminant mammals excels in protection in the first compartment of the stomach of a ruminant mammal and solubility in the fourth compartment of the stomach. This additive composition improves the nutrition of the feed with respect to such a basic amino acid as lysine, a substance frequently missing in the feed for ruminant mammals.
