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

摘要

Phosphoric acid- aminoacid-polyvalent metal complex salts of formula RaMgbMcHdPO4.nH2O (I) and RaaMgbaMcaHdPO4(PO3)m.n1H2O (II) are new. R = cation of a basic amino acid; M = m-valent metal, but not Mg; m = 2 or 3; a = 0.05-1.0; b = 0.85-1.43; c = 0.02-0.6; d = 0-0.3; a+2b+mc+d = 3; n = 0-20; aa = 0.05-0.4; ba = 0.9-1.47; ca = 0.01-1.4; d = 0-0.3; aa+2ba+mXca+d = m+3; m = 0-1.12. Also claimed is a powder or granular feed additive composition for ruminants containing a complex (I) which is insoluble in neutral and alkaline water, and soluble in acidic water.
