Biosecurity in Dairy Farms: Practical Strategies for Disease Prevention

Biosecurity is a fundamental component of dairy herd health management, aimed at minimizing the introduction, establishment, and spread of infectious diseases within and between farms. Effective biosecurity encompasses animal movement control, quarantine protocols, hygiene and sanitation, visitor management, equipment disinfection, feed and water safety, pest and wildlife control, carcass disposal, and vaccination programmes. Farm design, employee training, surveillance, and disease reporting also play critical roles in maintaining herd health. Implementing practical, risk-based biosecurity measures reduces disease incidence, improves animal welfare, enhances milk production, minimizes antimicrobial use, and strengthens the sustainability and profitability of dairy farming operations.
