Biosecurity in poultry farm, How to keep healthy , Part-1


 Biosecurity in poultry farm


  • Biosecurity is a set of management procedures that aim to limit the introduction and spread of disease – causing microorganisms into a poultry farm.
  • In simple say, bio-security means protection (security) of bird from harmful biological (bio) organisms.

 Infectious agents:                                    

  • Viruses (Avian Influenza, Gumboro, ND etc.)
  • Bacteria (Colibacillosis, Pasteurellosis, Salmonellosis etc.)
  • Fungi (Aspergillosis etc.)
  • Protozoa and Parasites

(Coccidiosis, Intestinal worms etc.)

Objectives of Biosecurity:

  1. have To keep lethal, highly contagious diseases out of premise
  2. To reduce challenges by common pathogens known to reduce productivity- e.g. E coli, Coccidiosis etc.
  3. have To eliminate immunosuppressive agents such as – MD, CA, IBD etc.
  4. Must be  reduce contamination with agents of public health significance such as- Salmonella or Compylobacter.

Three key levels of Biosecurity:

  • Conceptual Bio-security
  • Structural Bio-security
  • Operational Bio-security

Conceptual Bio-security:

  • Involves sites planning
  • Location e.g. proximity to other farm’s transport etc.

Almost impossible to change once committed without very high cost.

Structural Bio-security:

  • Concerns the design of the farm and buildings.
  • Includes house design (easy to clean), site layout and security.

Operational Bio-security

  • Minimize the no. of visitors to the poultry farm by locking the entry gates.
  • All persons entering the farm should follow

Bio-security  procedures.

    – taking of showers

– wearing clean farm clothes

  • Quarantine restriction (3 to 5 days) since visitation must be mandatory for all individuals
  • Follow all in all out system.
  1. General procedure
