Biosecurity “Protection from exposure to disease” What? Why? How?
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
Disease Control Methods Vaccination Medication Biosecurity
Control of “Management Diseases” Calf Pneumonia Calf Scours High cost to the industry worldwide Mortality Poor growth Poor Feed conversion Cost of Medication
Biosecurity Requirements of the Dairy Farm Maintenance of stock health Protecting the production potential Protecting the quality of the product
Maintain Standards in all areas Cubicles Calving Facilities Calf rearing Collection Area Milking Parlour Dairy
STAGE 4 DISINFECTION To remove residual challenge Use broad spectrum disinfectant Cover all surfaces Cover all cracks & crevices Allow to dry.
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
CONTINUOUS DISINFECTION Control Access Foot & Wheel Dips Water Sanitization Aerial Disinfection Rodent Control
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
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
Cattle Biosecurity Collecting Area Prevention of Mastitis Disinfect after each cleaning
Cattle Biosecurity Milking Parlour and Dairy High standards Practiced Use broad spectrum disinfectants after cleaning in the parlour
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
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
Conclusion Freedom from Disease = Maximum Profits
