The American Society of Agricultural and Biological Engineers (ASABE) has
initiated a project to revise the current testing procedures for
Solids-Mixing Equipment for Animal Feeds.
The use of salt (sodium chloride), the tracer primarily
referenced in the existing standard, has limitations in validating mixer
performance, particularly in validating the mixing of microingredient (drug)
feed additions and in validating "augmentation" or cross-contamination control
Colored iron particles
In these situations, alternate
tracers may be required, but their reference in the standard is vague and
unclear. It is therefore revised to specifically reference the use of
colored iron particles or colored iron powder as tracers.
Revising the standard to permit the use of colored iron
particles will allow US and Canadian feed manufacturers to satisfy both domestic
regulatory and non-regulatory testing requirements while also satisfying
requirements of trading partners in Europe.
