Abstract
A method of preparing a near-neutral homogeneous mineral composition containing an excess of strong anions over strong cations for supplementing ruminant animal feeds, wherein magnesium and calcium chlorides are admixed with a molecular excess of ammonium sulfate and water and heated until a liquid phase is formed in which a metathetical chemical reaction occurs to substantially form homogeneous particles of magnesium and calcium sulfates, ammonium chloride and excess ammonium sulfate. Addition of granule binders and conditioning clays allows preparation of minigranules from damp agglomerates formed during the reaction. The minigranules exhibit a high degree of strength, palatability and storage stability. The minigranular anionic salt composition prepared by the new method was found to be an effective mineral feed supplement for ruminant animals, particularly for preparturition cows.
