Bovine Biosecurity: Disease Prevention as Welfare Priority

Key Welfare Facts

Biosecurity failures are the primary route for introduction of new pathogens causing welfare emergencies in herds.
Purchased cattle are the single highest risk factor for disease introduction including PRRS, BVD, and Johne's disease.
Testing incoming cattle before introduction and isolating for 3-4 weeks dramatically reduces disease transmission.
Visitor protocols, vehicle disinfection, and vermin control reduce environmental disease introduction risk.
Farm-specific biosecurity plans developed with a vet identify and address the highest-risk pathways for each unit.
Biosecurity investment prevents disease outbreaks that cause mass suffering and require extensive antibiotic use.

Welfare Assessment

Farm biosecurity is fundamentally a welfare investment that prevents the acute welfare emergencies caused by introducing new diseases. Developing a farm-specific biosecurity plan with a vet and implementing it consistently represents one of the highest-return welfare investments available.

What You Can Do

Develop a farm-specific biosecurity plan with your vet identifying the highest-risk introduction pathways
Test all purchased cattle for key pathogens including BVD and Johne's before introduction to the herd
Implement at least 3-4 week isolation protocols for all purchased stock before herd contact
Establish visitor, vehicle, and vermin control protocols as part of routine farm management
