Maintaining a healthy herd begins with robust traceability and recordkeeping. With cattle often moving between birth, stocker, and finishing operations, maintaining detailed records of animal health status, movement history, and treatment events is essential. Even without electronic ID, good paper or software-based records support early detection and rapid response during disease events.

Before introducing new animals into the herd, producers should implement strict test-and-quarantine procedures. Testing for diseases like BVDV, Johne's, and trichomoniasis is recommended, followed by a 30-day isolation period. This reduces the risk of introducing pathogens into a stable herd environment.

A well-designed vaccination protocol-developed in collaboration with a veterinarian-is another key layer of defense. Vaccines help build herd immunity, reducing vulnerability to viral and bacterial infections. Proper nutrition and low-stress handling further support immune system performance, especially in young or transitioning animals.

In the event of illness, segregation of sick animals is critical. Designated "hospital pens," proper treatment sequences (tending to sick animals last), and rigorous sanitation of clothing, boots, equipment, and facilities limit the spread of pathogens. Antimicrobial treatments should only be used under veterinary guidance, and hygiene between pens should be non-negotiable.

Finally, biosecurity works only when integrated into day-to-day operations. All employees should be trained to follow established protocols. Partnerships with veterinary services, extension agents, and programs like Beef Quality Assurance (BQA) or Secure Beef Supply (SBS) can enhance protocol design and implementation across operations of all sizes.

Why It Matters for U.S. Agriculture

• Disease outbreaks result in major economic losses, halted movement, and reputational damage.

• Strong biosecurity safeguards commodity prices and maintains consistent livestock yields.

• Healthy herds are more resilient to environmental stress, enabling integration with feed supply chains and crop-livestock systems.

• Participating in federal programs like livestock insurance or emergency response initiatives often requires documented biosecurity measures.

From traceability and testing to vaccination and staff training, biosecurity is a manageable, affordable insurance policy for U.S. livestock producers. As animal health becomes increasingly central to supply chain stability and food security, producers must make biosecurity a top priority-not only to protect their herds, but to strengthen the entire ag economy.
