Location Selection

  • Farm should be minimum 500 meter away from the main road and from the hatchery and processing plant
  • Young birdshouse and hatchery should not be in down wind direction
  • Avoid construction in lowland which is prone to water stagnation andfrequented by migratory birds

All In All Out Program:

  • Rearing birds of different age groups should be avoided
  • If birds of different age groups are present in the farm, young flock must be visited first

Structural Biosecurity:

  • Physical barriers like gate, fencing & biosecurity board to ensure restricted entry
  • Farm entrance should have single gate with all facilities of disinfection and vehicle wash
  • Clean and dirty area of farm should be separate with restricted traffic
  • Facilitieslikemandatory disinfection tunnel, wash basin and shower room are recommended
  • Houses should have functional foot bath and Vermin free design
  • Proper facility for feed storage, necropsy examination and dead bird disposal should be made
  • There should be a gap of minimum 30 meters between the sheds having birds of different age groups
  • Farm Premises should not have fruit bearing plants, tall vegetation and water-logging issue

Operational Biosecurity:

  • Restricted entry of person, vehicle and animals inside the farm premises
  • No animal or bird ( Pet/ Wild/ Desi) should be allowed inside the farm premises
  • Equipments and other materials should not be exchanged among farms
  • Labors should be exclusive to the farm/ shed and must practice all hygienic practices
  • Separate footwear and dress should be provided at farm entrance for visitors
  • Visitor should be preferably not exposed to poultry houses for at least 12 hours
  • Chick boxes, vaccine vials, bedding material and dead birds should be disposed as per procedures
  • Sick birds should always be visitedlast after visiting healthy birds and clean area

Cleaning & Disinfection:

  • Proper cleaning is a necessary step before disinfection
  • During empty shed cleaning, insecticide spray, dry cleaning, disinfectant pre-spray, detergent wash, white wash and fumigation/ thermal fogging should be followed
  • Triple salts or Quaternary Ammonium Chloride (QAC) + Glutaraldehyde combinations are preferable for pre-spray and regular spray while Phenol group or Aldehyde groups should be used for terminal disinfection
  • Water tank should be properly scrubbed and cleaned using detergent followed by bleach
  • Biofilm and lime scales from pipeline should be removed using hydrogen peroxide and peracetic acid (Acid)(empty shed)
  • Water acidifiers and sanitizers should be used regularly to reduce thebuild up of scales, biofilms and microbial load (Chlorine, Iodine or Ammonium compoundslike bromochlorodimethylhydantoin- BCDMH, sodium dichloroisocyanurate- NADCC, didecyldimethylammonium chloride- DDAC, hydrogen peroxide- H2O2 can be used)
  • Minimum 10-15 days rest period should be practiced in between flocks and it should be utilized for efficient cleaning and disinfection
  • Well designed shed cleaning and disinfection program should be strictly followed

Biosecurity Monitoring:

  • The farm and hatchery should be periodically monitored for biosecurity efficiency
  • Touch plates, air exposure plates, chick fluff and swabs are the efficient means for monitoring
