Abstract
A supplemented animal feed composition comprising (a) an animal feed that is deficient in a trace metal admixed with (b) a diet-supplementing effective amount of a polyvalent metal cation propionate having the formula M(CH.sub.3 CH.sub.2 COO.sup.-).sub.x, wherein M is a polyvalent metal cation form of said deficient metal that is selected from the group consisting of Zn.sup.+2, Cu.sup.+2, Fe.sup.+3, Fe.sup.+2, Mn.sup.+2, Co.sup.+2 and Cr.sup.+3, and x is an integer equal to the cationic charge of M. The metal propionates are used as biologically available and economical sources of trace metal for supplementation in animal diets.

A supplemented animal feed composition comprising (a) an animal feed that is deficient in a trace metal admixed with (b) a diet-supplementing effective amount of a polyvalent metal cation propionate having the formula M(CH.sub.3 CH.sub.2 COO.sup.-).sub.x, wherein M is a polyvalent metal cation form of said deficient metal that is selected from the group consisting of Zn.sup.+2, Cu.sup.+2, Fe.sup.+3, Fe.sup.+2, Mn.sup.+2, Co.sup.+m and Cr.sup.+3, and x is an integer equal to the cationic charge of M.
A process for the nutritional supplementation of animals that comprises feeding animals whose feed is deficient in a trace metal selected from the group consisting of zinc, copper, iron, manganese, cobalt and chromium using a supplemented feed comprising that deficient feed admixed with a diet-supplementing effective amount of a polyvalent metal cation propionate having the formula M(CH.sub.3 CH.sub.2 COO.sup.-).sub.x wherein M is a polyvalent metal cation selected from the group consisting of Zn.sup.+2, Cu.sup.+2, Fe.sup.+3, Fe.sup.+2, Mn.sup.+2, Co.sup.+2 and Cr.sup.+3, and x is an integer equal to the cationic charge of M.
