A feed additive for ruminant prepared by dispersing an active substance such as amino acids or vitamins in a protective substance mainly comprising metallic salts of fatty acid mixtures and granulating the dispersion and employed to allow the active substance to bypass the rumen to be digested and absorbed in the abomasum and the subsequent stomachs. It now becomes possible to well balance the active substance between the capability of bypassing the rumen and the digestibility and absorbability in the abomasum and the subsequent stomachs. |
