1
DISEASE PREVENTION
There are basically 2 types of diseases that
must be considered in poultry production:
•diseases of detriment to bird health
•diseases of potential human health
concerns
2
CAUSES OF HEALTH ISSUES
• Pathogens
• bacteria, viruses, parasites, protozoa, fungi
• Nutritional deficiencies
• Chemical poisons
• Overmedication
• Poor management
3
BIOSECURITY
What is “Biosecurity”?
• Protecting your birds from disease
• Preventing or controlling disease transmission by
vectors
What is a vector?
• Something that may transmit a disease
• Rodents, birds, insects, shoes, car tires, shared
equipment, best friend, pet, feed, water, dust, air….
4
BIOSECURITY
•
Preventative strategies to control disease
causing organisms and their carriers
(vectors).
•
Protection of poultry flocks from any type of
infectious agent.
•
Control transmission of disease from flock to
flock.
Biosecurity is the cheapest, most effective
means of disease control available.
5
WHO SHOULD PRACTICE GOOD
BIOSECURITY?
Everyone!
• Commercial producers
• Small flock/backyard poultry owners
• Hobbyists/breeders
• Youth poultry project owners for livestock
shows (4-H and FFA members)
6
WHY SHOULD I BE CONCERNED
ABOUT BIOSECURITY?
Because of what might happen:
• Disease and high mortality in flocks
• Infected flocks euthanized
• Loss of income for producers
• Higher prices of poultry meat and eggs
• Quarantines and restricted
movement/sale of birds
• Cancellation of poultry shows
7
MAJOR COMPONENTS OF
BIOSECURITY
• Flock Management
• Traffic Control
• Isolation
• Cleaning/
Sanitation
8
BIOSECURITY MONITORING POINTS
• Humans
• Equipment
• Environment
• Animals
• Contaminated eggs and chicks
• Contaminated feed
9
ENVIRONMENTAL ROUTES OF
DISEASE TRANSMISSION
Environmental contaminants:
• wind
• water
• dust
• feathers
• manure
Drying and sunlight are very effective at
killing many disease causing organisms.
10
GOOD BIOSECURITY
PRACTICES
• Keep pets, wild birds and animals and other
livestock away from the flock
• No trading or purchase of untested birds –
quarantine new birds
• Use dedicated footwear/clothing or disposable
coveralls and boot covers when checking your
birds
• Hand washing before and after handling birds,
manure, coops, eggs, etc.
11
ISOLATION MEASURES
• Confine flocks to controlled environment
• Screen houses to protect flock from wild
birds
• Avoid contact with migratory waterfowl
and other birds
• Restrict visitors
• Do not share equipment, coops or
leftover feed
12
REDUCE EXPOSURE RISKS
• Control vector habitat and attractants
•
•
•
•
birds
rodents
varmints
insects
• Make sure pen is animal and bird proof
13
MAINTAIN FLOCK HEALTH
Minimize stressors to prevent increased
susceptibility to disease
• Fresh feed
• Clean water
• Clean, dry litter
• Good ventilation
• Provide an overall comfortable environment
14
CLEANING AND SANITATION
Five steps to cleaning and disinfection (C&D)
1. Dry Clean (remove all organic matter)
2. Soap
3. Rinse
4. Dry
5. Disinfect
15
DISEASE/HEALTH CHECKS
•
Watch for symptoms such as:
• Coughing, sneezing, watery eyes,
ruffled feathers, loss of feathers,
excessive picking, labored breathing
and sudden drops in production and
feed or water consumption
•
Eliminate unhealthy or
nonproductive birds
•
Check birds periodically for
lice, mites, and worms
