BIOSECURITY FOR POULTRY
Commercial flocks and small flocks:
Use same techniques to prevent
disease
Same diseases threaten both
Objectives:
 Disease prevention through effective
biosecurity practices- keep diseases
out!
 If breakdown in biosecurity and disease
challenge occurs, ensure chickens are
immune competent to limit losses
Disease organisms get to other farms by one
of the above ways 90% of the time. Break
the cycle!

organism, common in layer
industry
FOWL POX
Viral disease, spread by
mosquitoes and direct contact,
controlled by vaccination
MAREK’S DISEASE
Viral disease, causes tumor
formation, controlled by
vaccination
CANNIBALISM
Genetics predisposition,
management factors, controlled
by trimming beak, reduced light
intensity,…
ASCARIDS AND
TAPEWORMS
Common, litter management,
treatment as needed
---Be on the lookout!---
AVIAN INFLUENZA
Viral disease, severity varies from
LPAI to HPAI, common,
vaccination may be practiced in
some situations
Conclusions
Take home message:
Goal: to prevent entry of diseases into your
flocks by use of biosecurity practices
Plan: develop and implement a common
sense disease prevention program
