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

3. 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

4. Disease Control Methods Vaccination Medication Biosecurity

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

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

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

8. TYPES OF DISINFECTION Terminal Continuous

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

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

11. STAGE 3A WATER SYSTEMS Drainable –Drain –Clean –Disinfect –Flush Non-Drainable –Clean –Sanitize

12. STAGE 3B REMOVABLE EQUIPMENT Soak Scrub / Pressure Wash Detergent Sanitizer Disinfect Dry

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

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

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

16. 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

17. 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

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

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

20. 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

21. 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

22. Conclusion Freedom from Disease = Maximum Profits
