The Chicken House

Overview

General overview of C&D

·         Detailed review

·         Darkling beetle infestation

·         Rodent infestation

·          Water, a source of infection

The Objective

                   To clean and disinfect the poultry house so that all potential poultry and human pathogens are removed and to minimize the numbers of residual bacteria, viruses, parasites and insects etc. between flocks minimizing any effect on health, welfare and performance of the subsequent flock.

Clean out Stages

  1. Planning                                           2. Depletion

  3. Insecticide application                        4. Rodent control

  5. Remove dust                                    6. Pre-soak

  7. Remove equipment                        8. Remove litter – litter disposal

 9. Cleaning of water lines                       10. Reapply insecticide

11. Sweep                                               12. Washing

13. Drying                                               14. Disinfection

15. Reapply insecticide                            16. Fumigation

17. Rodent control

Planning

                               “Make a plan for depletion and next flock placement.”

Depletion

                             “Simply culling of breeders flock after the age of 64 weeks “

 Darkling Beetles and Disease

• IBDV, MDV                                         • NDV and AIV

• Reo viruses, ILT, Fowl Pox           • Salmonella

• Campylobacter                                     • E. coli 

• Aspergillus, Staphylococcus                • Coccidia

• Roundworms                                     • Fowl tapeworm

Facts Facts

                   There can be up to 2 million dark ling beetles and larvae in a broiler house

•               Average beetle size (≈6mm long, 100mg)

·              Assuming beetles convert feed as  well as broilers; bug load could cost 1 point of          FCR

•                In a complex killing 1 million birds/week, 1 point of FCR can cost up to an estimated       $300,000/year

Life Cycle

Life cycle of darkling beetles

Effective darkling beetle control program

• Identify darkling beetle infestation

• Keep litter moisture low (key nutrient    for larvae and beetles).

• Regular maintenance of water lines will prevent leaking and will help reduce beetle        numbers.

• Use a pesticide that is suitable for the type and location of treatment.

Follow label instructions for application procedures and rates.

• Rotate insecticides and the use of boric acid.

• Treat within 24 to 48* hours after birds are removed from the house.

• Apply treatments in a manner that can reach beetles and larvae that may be several        inches under the litter. Use the highest permitted rate.

• In some cases treating the house twice between flocks will ensure that the beetle            population is reduced significantly
   application and only mix it within a 2 to 3 inch depth.

Alphitobius diaperinus

Controlling Alphitobius diaperinus

In Broiler Houses

• Trials were conducted during one year under field    conditions

• Tested combined treatment

— Adulticide – cyfluthrin [sī-floo-thrǐn]

— Larvicide - triflumuron [trī-floo-mūrǒn]

• The combined insecticide treatment greatly reduced the adult and larval stocks throughout the different broiler growing periods, and control of A. diaperinus populations was achieved by the end of the second

 Darkling Beetles Eat Feed

·         There can be up to 2 million darkling beetles and larvae in a broiler house

·         Average beetle size (≈6 mm long, 100 mg) and assuming beetles convert feed  as well as broilers; bug load could cost 1 point of FCR

·         In a complex killing 1 million birds/week, 1 point of FCR can cost up to an estimated $300,000/year

Rodent Control

Estimating Rat Populations

• Rule of thumb:

—If you don’t see rats but see signs of them, there are ~1 to 100

—If you see them occasionally at night, there are ~100 to 500

—Occasional daytime and numerous night sightings indicate ~400 to 1,000

—Seeing several in the daytime may indicate a presence of as many as 5,000.

 Fill Gapes

Cats and Dogs Can Carry

Pathogens

• If it can’t be wet

Cleaned or removed-

Dry clean and cover it up!

• Environmental sensors etc!

Remove Litter

 • Remove all litter and debris

• Final dry brush of floor

• Avoid windy weather

• Use covered trailers

• Disinfect wheels

Litter Disposal

• > 2 km from the farm

• Method of disposal

— Spread and ploughed in arable land

— Landfill

— Composting

— Incinerating

— Nitrates

Washing

Internally and Externally

• Pressure washers-

100 bar min

• Preferably hot water > 40oC

• Suitable Chemicals

• Visual Check

Poultry Water Line Cleaning:

Overrated or Underappreciated?

“The evidence is growing that water sanitation can be a crucial tool in   addressing poor poultry flock performance”

When the poultry industry advanced from open drinkers and troughs to enclosed nipple lines, it was the perfect solution to both labor and contamination challenges. Yet the test of times has proven that while enclosing water supply in a poultry barns has greatly improved water sanitary qualities, it has not eliminate the risk of disease challenges.

Bio film Slime

 • Poor line sanitation _ bio film

• Bio film lives on very little nutrients

                        • Can cause health challenges, flock after flock

• Disease agents like E. coli and Salmonella

— Salmonella may be isolated from 7 to 8% of water samples collected from nipple   drinker systems.

• Once established is 10-1000x harder to remove

• Can return in 2-3 days after cleaning

— When we do a poor job of cleaning

— When we don’t keep water sanitized

— When we add food supply

What Influences Bio-films?

• Natural contaminants Iron, manganese, sulfur                

• Vitamins              • Electrolytes         • Organic acids

• Sugar water                                         • Vaccines and vaccine stabilizers

• Probiotics and Antibiotics               • Do you clean lines after product use?

• How often is water sanitation?

 sacrificed so water can be delivery route for products?

Water System

• Drain pipes and tanks        • Flush lines

• Cleanse header tanks                       • Scale / bio film removal

• Refill tanks and add sanitizer          • After 4-24hrs remove solution         

• Rinse with fresh water

• Run sanitizer solution through lines (check no air locks)

Feed System

• Ensure bulk bins and augers are free of feed

• Dry brush

• Do not introduce water to the bulk bins!!

• Wash and disinfect pans, tracks, auger pipes etc

Repairs and Maintenance

• Prior to final disinfection

• Gas and electrics

• Buildings and Equipment

• Concrete Repairs

• Vermin proofing

• Wild bird proofing

• Clear Drains

        Disinfection

         • Only when buildings are internally and                     externally clean

         • Repairs are complete

         • No organic matter

         • Correct dilution rates

         • Remember the sequence

!Disinfectant doses and cleaning schudle

 Fumigation                                                   Monitoring Effectiveness

• Damp Surface (not puddles)                                   • TVC’s Total Viable Counts

• Seal house tight                                                          • Salmonella

• Warm house to 21oC (70RH)                                   • Set Standards     

 • Seal gas in house for  24 hrs                                  • Monitor Trends

Summary

 • Adopt, develop standard operating procedures

• Clean and disinfect after every flock

• Monitor effectiveness

• Darkling beetles and rodents are potential sources of Salmonella, etc.

     • Water is often neglected

• Allow adequate down time between
