DOBLE-COATED VITAMIN C AND THE ANIMAL NUTRIENT CONTAINING THE SAME

摘要

A feed supplement containing a double coated vitamin C is provided to enable the double coated vitamin C to stably move to the lower digestive system without being decomposed by microorganisms, pH and moisture in the rumen and to be absorbed in the lower digestive system and thus increases weight and productivity of ruminant animals. A feed supplement containing a double coated vitamin C is obtained by the steps of: producing a first encapsulated vitamin C by mixing vitamin C and a binding/coating agent and extruding; and mixing the first encapsulated vitamin C, extremely hydrogenated fat and fatty acid with a melting point of 40deg.C or more and encapsulating them. The vitamin C is selected from ascorbic acid or ascorbic acid derivatives. The binding/coating agent is selected from the group consisting of a divalent soap comprising bees wax, PEG, surfactants, calcium stearate, zinc stearate and magnesium stearate; a monovalent soup comprising sodium soap and potassium soup; fatty acid comprising hydrogenated fat, extremely hydrogenated fat, palmitic acid and stearic acid; and water, PG, high fructose corn syrup, cellulose, silica and zeolite.
