Minimum vacant time before arrival of chicks is 2 weekDepopulate the house Take out all removable equipments and repair themRemove all feed i.e. harden and stuck to the equipment,

floor and wallsRemove cobwebs and dust from walls, ceiling etc

Remove the litter and dump it in remote parts of the farmScrub walls, floor and equipments with hot lye lotion (1/2

kg per 20 gallon water), apply it on equipments for 2 hours then wash

With a blow lamp/gas burner, burning of ceiling if it is made of concrete, walls, crakes, crevices, wire netting and floor

White wash the house (20g/drum of water) also add CuSO4 @2g/gallon. The walls , roof and floor all should be white washed if not possible then the walls should be white washed at least 3 feet upto from the floor.

Fumigate the house at least 1X concentration

Apply insecticides on floor, walls and junctions Vacant the farm for at least one weekProper cleaning and disinfection of equipments with

potassium permegnateflush and sanitiz drinker lines prior to arrival of chicksThe water quality, purity, and temperature must be

checked in advance. Water should be within the correct temperature range

(65–75ºF; 18–24ºC).

The hover and the wire netting should be nice clean and disinfectedStore the required spare equipments

Note:Disinfectants

Formalin (10% spray) is good disinfectant especially for respiratory diseases

Hot boiling water…………… washing equipment and

wall (round about 2 feet)

Phenyle (5% solution) ……….in case of IBD

Other disinfectants which may be used Lysol (1-2%)Novan (1.5-2%)Negavon (15g/gallon water)Adicol spray 1%

Plan (Time frame)

5-6 days

Organic material removal

Rodents control

Insecticide

Pre flock managementSimple water washing

Washing with detergents and use H2O2 for bio-film

removal

Chemical treatment

Acid treatment (Virorcid 0.5%)

Base treatment (KOH)

Pre flock management

• Burning

• Fogging

• Fumigation

What is Disinfection???The destruction of harmful micro-organisms.ButNot the destruction of all micro organisms.

Reduction in number to an acceptable level.To a level not harmful to health.

CleaningCleaning is the physical removal of organic matter. Detergents are used for cleaning.

Disinfectants don’t clean, they disinfect.

What is organic matter?

Old litter, droppings, feathers etc.

Types of CleaningTYPES OF CLEANINGDry cleaningWet cleaning

Removal of Equipment & Old Litter

Remove any residual feed from the feeder system and

silo.

Remove all movable equipments from shed.

Remove all old litter from the house.

Dry CleaningBrush and Blow all surfaces to remove dust from

ceilings, floor, walls, water lines, fan, boxes, inlets,

electrical motors and silo. Use broom stick, brushes

and blowers etc.

Surrounding area is also dry cleaned.

It is utmost important to remove feathers and old

litter etc. from the vicinity of the shed.

Wet Cleaning

Soaking, washing & scrubbing.

SoakingSoak all surfaces including

o Floor o Roof o Walls

o Feeding Line o Drinking Lines o Fans

o Pads o Inlets o Partitions

o Pillars

Scrubbing of ShedScrub the floor, walls and pillars with brush/ scrubber

machine.Use floor washer to remove any dirt or organic matter

from the floor by jet pressure of water.

Hot Water Washing & DryingWash all surfaces with hot water (90°C) using high

pressure washer machine.

After washing, dry out whole shed before disinfectant

application.

Cleaning of Drinking System1. Main water tank cleaning2. Drinking lines cleaning

Use appropriate disinfectants/sanitizers in right dilution & give proper contact time.

Flush out with clean water to remove any debris or bio film.

Disinfectant ApplicationPlace removable equipment in the shed after proper

cleaning.

Seal the shed properly.

Apply disinfectant in right dilution and in proper way.

Spray into the apex of the roof and work down the walls to

the floors.

Ensure that every part of the shed be covered with

disinfectant solution.

Disinfectant Application Give proper contact time (8 to 12 hours) after

applying disinfectant in the shed.

Upon completion of the disinfectant process, place

disinfectant foot dips at all entrances.

Broad spectrum: should have a wide antimicrobial spectrum

Fast acting: should produce a rapid kill

Not affected by environmental factors:should be active in the presence of organic matter (e.g., blood, sputum, feces) and compatible with soaps, detergents, and other chemicals encountered in use

Nontoxic: should not be harmful to the user or patient

Surface compatibility:should not corrode instruments and metallic surfaces and should not cause the deterioration of cloth, rubber, plastics, and other materials

Residual effect on treated surfaces:should leave an antimicrobial film on the treated surface Easy to use with clear label directions

Odorless: should have a pleasant odor or no odor to facilitate its routine use

Economical: should not be prohibitively high in cost

Solubility: should be soluble in water

Stability: should be stable in concentrate and use-dilution

Cleaner: should have good cleaning properties

Environmentally friendly: should not damage the environment on disposal

Swab TestingTake Swab samples to evaluate the disinfection

procedure.

Cleaning & Disinfection of Feed Room

Same procedure of dry cleaning, wet cleaning and disinfectant application is carried out as for shed.

Swab tests taken for fungal count.

Addition of Bedding in ShedAdd litter in shed ( might be rice husk or wood

shaving) in proper thickness.

Before input of bedding, take fungal count.

Fogging Fogging is done to control organisms introduced to the house during

the setting up procedure and to disinfect the air and other

inaccessible areas of the building.

1. Thermal fogging

2. Cold fogging

After doing fogging of shed, we take litter samples for fungal count.
