STABILIZED COLISTIN PREPARATION

摘要

PURPOSE:To provide a new preparation of colistin sulfate stable in a formula feed as a feed additive. CONSTITUTION:Starch is admixed with colistin sulfate and the resultant mixture is gelatinized and solidified by heating, thus producing the objective preparation stable in a formula feed. If the particle size of this preparation is made uniform, this preparation is further improved in stability, especially in a pellet-shaped feed.
