  5. Biosecurity
    A set of management practices that prevent infectious diseases from being carried into a herd
  6. What are the 4 areas of biosecurity
    • Isolation/Quarantine
    • Testing
    • Vaccination 
    • Sanitation
  7. Isolation/Quarantine
    • Incoming animals held in isolation until health status is determined (usually 3 weeks)
    • Works well for short incubation period diseases 
    • Isolated animals should not share same air space, food, or water as established herd
  8. Isolation
    • Separate sick from healthy
    • Hospital pens
  9. Testing
    • Especially for imported animals (breeding stock)
    • Testing can establish disease free status 
    • Purchase semen from disease free herds only
  10. Vaccination
    • Are intended to safety expose animal to weakened infections agent so that immune system is prepared for future attack 
    • Contains killed or weakened infectious agent 
    • Animal reacts to vaccine by making protective substances called anibodies
  11. Sanitation
    • All visitors should wear clean boots and coveralls 
    • Disinfect boots between barns/rooms 
    • Prevent fecal contamination of feed supplies by dogs, cats, birds, rodents, and wildlife 
    • Separate equipment for manure and feed handling
  12. Health
    • Not merely the absence of disease s
    • State of optimal physical, mental, and social well being 
    • linked to welfare
  13. Health and Welfare
    • Stressed animals grow slower 
    • Stressed animals are more susceptible to pathogens 
    • Diseased stock may be rejected or docked at market
  14. Optimal health balance
    • Preventing injury 
    • Avoiding disease 
    • treating symptoms animal welfare
    • economics of production 
    • Individual with group industry
  15. Pathogens
    • disease causing micro-organism
    • Bacteria viruses and others
  16. Avoiding Pathogens
    • Eliminate from herd if present
    • Avoid altogether if absent 
    • Isolate and test incoming animals 
    • Control access of fomites
  17. Fomite
    • Objects or materials that are likely to carry pathogens 
    • People, boots, clothes, equipment, vehicles, pets, birds, wildlife
  18. Sanitation
    • Regular removal of manure from pens 
    • Clean and disinfect pens between groups
    • Clean and disinfect boots between rooms, barns
    • Shower-in-shower-out
  19. Cleaning livestock facilities
    • High pressure, hot water
    • Soup is often effective
    • Foaming agent will decrease time and total water use
    • Rooms and equipment must be dry before adding new livestock
  20. All-in, All-out
    • Isolate groups of animals that are managed similarly
    • Avoid maxing age groups and pigs between pens
    • Ideally pen dividers would be solid 
    • Industry standard today 
    • Requires coordination and planning 
    • 7-10% improvement in daily gain and feed conversion
  21. Multi-site production
    • Variation of all-in, all-out
    • Geographically isolate different age groups
    • gestation/farrowing, nursing, and finishing
    • Reduces risk of spread of airborne (and boot borne) pathogens between buildings
  22. Keys to maintaining pathogens
    • Clean facilities - remove pathogen's environment 
    • Avoid contact - dirty boots, nose to nose, air exchange
    • Isolate sick and treat
