  1. Biosecurity • “Protection from exposure to disease” • What? • Why? • How?

  2. Biosecurity “A set of management practices which when followed correctly reduce the potential for the introduction and spread of disease causing organisms onto, and between sites.” From the perspective of the animal rather than just the farm

  3. Disease Control Methods • Vaccination • Medication • Biosecurity

  4. Biosecurity Control of “Management Diseases” Calf Pneumonia Calf Scours High cost to the industry worldwide Mortality Poor growth Poor Feed conversion Cost of Medication

  5. Biosecurity Requirements of the Dairy Farm Maintenance of stock health Protecting the production potential Protecting the quality of the product

  6. Maintain Standards in all areas Cubicles Calving Facilities Calf rearing Collection Area Milking Parlour Dairy

  7. TYPES OF DISINFECTION • Terminal • Continuous

  8. STAGE 1REMOVAL & DRY CLEAN • Remove stock • Equipment • Bedding • Gross organic waste • Dust

  9. STAGE 2CLEANING & SANITIZATION • Reducing infective material • Removal of dried on matter • Use a Detergent / Sanitizer • Allow to dry afterwards

  10. STAGE 3AWATER SYSTEMS • Drainable • Drain • Clean • Disinfect • Flush • Non-Drainable • Clean • Sanitize

  11. STAGE 3BREMOVABLE EQUIPMENT • Soak • Scrub / Pressure Wash • Detergent Sanitizer • Disinfect • Dry

  12. STAGE 4DISINFECTION • To remove residual challenge • Use broad spectrum disinfectant • Cover all surfaces • Cover all cracks & crevices • Allow to dry.

  13. STAGE 5AERIAL DISINFECTION • Covers inaccessible areas • Replace movable equipment first. • Can be done after bedding is spread. • Fog / Fumigate • Safety required with formaqldehyde. • Rest period

  14. Control Access Foot & Wheel Dips Water Sanitization Aerial Disinfection Rodent Control CONTINUOUS DISINFECTION

  15. Cattle Biosecurity Calving Clean the building of all organic debris Pressure wash Spray broad spectrum ddisinfectant After each calving remove bedding, cleansing and discharges Clean and disinfect Clean and disinfect buckets and utensils

  16. Cattle Biosecurity Cow Cubicles Control of Mastitis Pathogens Regularly clear organic debris Pressure wash with detergent sanitiser Disinfect cleaned surfaces Scrape central channel at least daily Reguarly clean and disinfect equipment and utensils

  17. Cattle Biosecurity Collecting Area Prevention of Mastitis Disinfect after each cleaning

  18. Cattle Biosecurity Milking Parlour and Dairy High standards Practiced Use broad spectrum disinfectants after cleaning in the parlour

  19. Cattle Biosecurity Care of housed calves • Pneumonia and scours cost the industry vast sums • Effective hygiene can prevent these two diseases • Situation similar to other intensive species • Poor ventilation, overcrowding and stock movements contribute • Hygiene is essential

  20. Cattle Biosecurity Cattle vehicle Biosecurity • Only essential vehicles to enter farm • Keep visiting vehicles outside biosecurity perimeter if possible • Vehicles should be cleaned and disinfected before arrival at the farm • Wheels, tyres and Wheel arches should be disinfected on arrival • Personnel should use foot dips, protective clothing and observe hand hygiene

  21. Conclusion Freedom from Disease = Maximum Profits
