1. BIO-SECURITY

2. What is Bio-security?
Bio-security
is securing
protection
from micro-
biological
organisms

3. •Helps keep out diseases
•Reduces the risks
•Limits the spread of disease
•Improves overall health of the flock
•Reduces mortality losses
•Improves profitability
Benefits of Biosecurity

4. Protection – Cheaper than
cure
•Proper cleaning and
disinfection are the most
important factors for hygiene
in poultry farms and
hatcheries

5. The infection pressure increases in :
•Regional density
•Farm density
•Poor sanitation
•Poor management
•Multi-age production
•Concurrent diseases
•Other species on farm

6. PROFIT versus LOSS
•A flock receiving good
health security care is a
delight and a source of
both pride and profit.
Failure to concentrate on
planned disease prevention
often leads to personal
disappointment and sometimes
disastrous financial loss.

7. Raising poultry
•Most broilers are
raised indoors on a
mud or concrete floor
that is covered with
litter (straw, sawdust,
or some other
material that absorbs
moisture), keeping the
birds clean.
Note - Litter care

8. Poultry Feed
•Poultry feed is
designed to
promote rapid
growth and
production.
•The main
ingredients are
maize and soya.
•And clean water

9. •Poultry farmers vaccinate their birds
against diseases
•Certain chemicals are added to the
drinking water to control growth of micro
organisms
•Respiratory ailments of poultry include
Newcastle disease, infectious bronchitis,
and laryngotrachetis, Marek's disease etc.
which kill many birds

How Disease is Spread

11. Understanding Microbial Control
•Sterilization - The
destruction of all infective
and reproductive forms of
microorganisms
•Disinfection - The
destruction of all vegetative
forms of microorganisms.
Spores are not destroyed
•Sanitation - The reduction of
pathogenic organism numbers
to a level at which they do
not pose a disease threat to
their host.

14. E.coli in Water



The dreaded Escherichia
coli belongs to the family
of Gram negative group
of anaerobic bacilli. It is
a non-spore forming rod
shaped bacteria. It
grows well on simple
artificial media at
temperatures of 15 to 40
C at pH 6.5 to 8.0. E.coli
is the index organism of
contamination.

15. Advantages of the Index
organisms:

i) E.coli survives in water
longer than most pathogens.
This makes it possible to detect
recent as well as earlier pollution.

ii) The presence of E.coli can
be easily detected in a short
period of time at low cost in
contrast to the more tedious,
costly and time consuming
identification of a specific
pathogen.

16. Limits
Properly filtered
water should have
total aerobic bacterial
counts < 1000 cfu.
Coliforms should be <
3 per 100 ml. E.coli
should be absent.

17. Factors affecting sanitized
hatchery
•The type of surface being treated.
•The cleanliness of the surface.
•The type of organisms being treated.
•The durability of the
equipment/surface material.
•Time limitations on treatment
duration.
•Residual activity requirements.

18. How can you prevent and control diseases
•In decreased order of efficacy
1. Implementing Biosecurity
2. Vaccination program
3. Medication
Often we use these three in combination
•Remember! - Prevention is always cheaper
than cure

19. •Post warning signs
•Lock buildings (check on company access)
•Log book of visitors to the farm
•Do not be afraid to ask where they have been
•Take measures to prevent contamination (boots
are the minimum)
•Family and friends are visitors
Control the Facility

20. Maximizing disinfectant
benefits
»Selecting disinfectants, considering their
effectiveness on organisms that are of
greatest concern
»Satisfy all efficacy requirements demanded
of disinfectants
»Allow adequate contact time (usually 30
minutes is sufficient)

21. Selection of Disinfectants
•Every farm has it’s unique problems
•No single molecule based
disinfectant is effective by itself
•Hence, a selective synergistic
combination formulated for
practical field conditions are most
effective

39. Current Biosecurity Situation

40. •The only animal that needs to be in a
chicken house is a chicken
•Active rodent control (bait stations and
fresh bait)
•Clean up spilled grain and feed
•Mow around the houses and weed control
•Keep your dogs and cats out of the poultry
houses
•Insects carry disease
Rodents, Animals and Insects

41. •Be aware of changes in mortality patterns
•Observe the birds
•Collect dead birds frequently
•Dispose of them in a proper way
•A pile of rotting birds is not composting: make
sure adequate temperature is reached
•Keep animals out of the composter
Mortality

42. •Clean and Disinfect shared equipment between
farms
•Establish a wash area away from the poultry
buildings
Shared Equipment and Vehicles

43. Some Tips on Biosecurity

44. Keep Distance
 
1.Restrict access to your property & your
birds.
2.Allow only people who take care of birds to
come into contact with them.
3.Do not allow your caretakers to attend
poultry exhibition & other farms.
4.Look for migratory birds/waterfowl & do
not let them near farm at all.
 

45. Know Warning Signs
• Sudden increase in mortality of your flock.
•Sneezing, gasping ,coughing and nasal discharge.
•Watery & green diarrhea.
•Lack of energy & poor appetite.
•Drop in egg production or soft or thin-shelled
misshapen eggs.
•Swelling around the eyes, neck & head.
•Purple discoloration of the wattles, combs & legs.
•Tremors, dropping wings, circling, twisting of the
head

46. Keep Clean
• Keep a pair of shoes and a set of cloths to wear
•Clean & disinfect shoes & laundry cloths
•Scrub shoes with long-handled scrub brush and
disinfectant .
•Wash your hands thoroughly with soap and
disinfectant before entering.
•Trolley-car, Truck tires must be cleaned with
disinfectant before entering.
•Keep cages, feeder water supply chain clean on daily
basis.
 

47. Biosecurity plan should focus on
•Preventing disease agents from entering the
farm
•By keeping potentially infected animals and
contaminated objects away from healthy
poultry.
•This requires formation of barriers –
Physical and/or Conceptual

48. Report sick birds!
 
–Call your local Veterinarians.
–Contact Regional Veterinary
Laboratory for detail disease
investigation.
–Early detection & reporting is the most
important step in eradicating
contagious disease outbreak. Do not be
afraid of “Crying Wolf”.

49. REMEMBER
If you take care of the
birds,
the birds will take
care of you!
