Downtime
Downtime is the time between the end of
disinfection and day zero
Downtime•No Animals•No Activity•Pathogens are exposed to dryness• Time varies based on pathogen
• Three times expected incubation period
•Block of area

IB مرض األلتھاب الشعبى
كيف ينتشر الفيروس
البراز
األفرازات من األنف و الفم
جيد ) ممھد تطھير(معظم الفيروسات يمكن القضاء عليھا باستخدام منظف
فيروس األلتھاب الشعبى يعيش جيدا فى الماء و :لذلك
الغسيل بالماء يساھم فى نشر العدوى
يجب زيادة الفترة الزمنية ما بين الدورات•• )يوم على األقل 10-15(
• من الطيور داخل المزرعة الواحدةعمر واحد يتم تربية • و ال ممھد تطھير قلوى / منظف بعد نھاية الدورة يتم التنظيف باستخدام

Cleaning and Disinfection
“CLEANING”
• Scientific definition:A process combining the physical input of energy with surfactant/detergent activity to remove organic material and associated micro‐organisms.
• Practical definition:Physical action with detergent giving the removal of organic material and99‐99.9% of organisms present.
Chemical Action
•Soils are electro‐chemically bonded to the surface. We must break that bond to remove the soils
•Cleaning “happens” at Neutral (pH = 7)
Cleaning With Chemistry
1‐ Identify the relative pH of the soil
2‐ Apply a product with the opposite pH
3‐Wait for some time for the chemistry to work

Clostridia
Beetles
Floor Treatments Of Poultry HousesCompound Application Rate Uses
Boric Acid Dust ‐ Baits Beetles
Salt (Sodium Chloride) 0.25 kg/m2 Clostridia
Sulphur Powder 0.01 kg/m2 pH reduction
Lime (Ca oxide, Ca hydroxide)
As necessary Disinfection
Caustic Soda (Sodium Hydroxide)
As Necessary Coccidia
Commercial Bleach (Sodium Hypochlorite)
As Necessary Disinfection
Water Line Treatment
Poorly Maintained Water Lines.
•1) Antibiotics and vaccines are not as effective.•2) Supplements such as vitamins and electrolytes are not as effective.
•3) An added stress due to higher bacterial counts •4) Poor performance.

Litter Management
Potential causes of wet litter
• • Improper ventilation• • Drinker type, management and maintenance• • Poor drainage, condensation and moisture seepage into litter• • High moisture bedding• • Poor bedding quality• • Inadequate bedding/litter depth• • Bird health• • Diet and water quality• • High bird density
Detrimental Effects of Ammonia
Ammonia Level Effects
20 ppm (Continuous for 6 weeks)
‐ pulmonary edema, congestion, and hemorrhage‐ increased susceptibility to respiratory disease due
to ciliostasis
40 ppm ‐ deciliation and decreased clearance ofE. coli from lungs and airsacs
25 – 50 ppm ‐ reduced body weights , feed efficiency andincreased airsacculitis in birds exposed to Infectious
Bronchitis Virus
50 – 100 ppm ‐ keratoconjunctivitis, corneal ulceration, and blindness
Litter Temperature (Brooding)
• The environmental conditions present when the chick arrives on the farm sets the pattern for the rest of the grow‐out
period.
• Chilled chicks undergo vasoconstriction to retain heat.This interferes with the passage of maternal antibodies into the chick through yolk sac absorption.
Litter Temperature (continued)
•Retained yolks play a factor in determining the presence of E. coli,
Salmonella, and Campylobacter on processed carcasses.
• The temperature of the litter at placement should ideally be 32 ‐ 35°C at the time the chicks are placed;
Foot Dips (Foot baths)
FootbathLocation
• Solid Surface (Concrete)•Close to the point of entry• Less clean >>>>> Dipping Clean• It may prove useful to have a tap and brushes nearby so that boots can be washed off before using the footbath.
FootbathLocation
• The area around the footbath should be disinfected at appropriate intervals to reduce the risk of disease transmission.
• The area around the footbath should remain as dry as possible as organisms can and will migrate and disperse in water.
FootbathDesign
‐ Long enough to walk through it.(Not to jump or stride over it)
‐ Easy drainage and cleaning.‐ Depth: at least 10 cm.‐ Should be protected from weather.
FootbathUse
• footbath is not designed as a footwear washing point!
•Boots should first be cleaned and then disinfected.
•Use smooth sole footwear (boots).
