How should acidifiers, organic acids and feed preservatives be specified?

List each active acid or salt, concentration, carrier, physical form, assay range and intended technical function. Assess corrosivity, worker handling, equipment compatibility, buffering, mixing and the difference between preserving feed and influencing animal performance. Conditions of use and permitted claims vary by substance and market. The commercial specification should also control moisture, bulk density and relevant contaminants, with clear directions for the final feed application.
