The term “residue prevention” most often conjures up thoughts of oral and injectable pharmaceutical products, but they aren’t the only culprits.

According to the Dairy Animal Care and Quality Assurance program manual, it’s important to follow the on-label guidelines for all feed additives, too.

Remember these key tips:

  • Use only FDA-approved medicated feed additives in rations.
  • Use any medicated feed additives in accordance with Food and Drug Administration Good Manufacturing Practices regulations. This applies to both suppliers and on-farm ration formulation.
  • Follow Judicious Antimicrobial Use Guidelines (found on page 26 of the manual).
  • Avoid extra-label use of feed additives, which is illegal and strictly prohibited.
  • Strictly follow withdrawal times to avoid violating residues, keeping in mind that withdrawal times for meat are often longer than the withholding time for milk.  Ensure that all additives are withdrawn at the proper time to avoid volatile residues.
  • Keep complete records when formulating or feeding medicated feed rations. Records are to be kept a minimum of 24 months from date of transfer of ownership.

Remember, every dairy animal eventually becomes a beef animal and the time to consider withdrawal times is before a product is used.
