Biosecurity of a poultry farm.pptx

Poultry farm biosecurity

1. Biosecurity in Poultry Production

2. What is biosecurity Bio" refers to "life" and "security" implies some sort of protection. Hence , "biosecurity" refers to a type of program that is designed to prevent disease causing organisms coming in contact with birds on the farm.

3. Why We Need Biosecurity? To keep lethal, highly contagious diseases out of premises e.g. Newcastle disease (Fowl Pest), avian influenza, or acute Gumboro disease. To reduce challenge by common pathogens known to reduce productivity such as E.coli and coccidiosis.

4. There are three types of Biosecurity: Conceptual Biosecurity Structural Biosecurity Operational Biosecurity TYPES

5. It is best to build farm in isolated area. In the case of Breeders, the farm should be away from the major road ways. Maintain enough distance between Breeders and grow-out-farms, such as Hatcheries and Feed mills. CONCEPTUAL BIOSECURITY

6. Fencing of farm perimeter to prevent unwanted visitors. Test water source for Minerals, Bacteria and Pathogen load. Suitable location for storage feed bags. Facilities for safe scientific disposal of dead birds. STRUCTURAL BIOSECURITY

7. Maintain records for visitors and their purpose. In Breeder Farm, all visitors and workers require to shower and use clean farm clothes to prevent cross contamination between them. OPERATIONAL BIOSECURITY

8. Transmission of pathogens Pathogens are transmitted in the fallowing ways, Fecal to oral Aerosol Mechanical vectors Biological vectors

9. Fecal to oral Spread of pathogens when feces of an infected birds or visitor ingested by a susceptible chicken

10. Aerosol Transmission of disease due to design of poultry houses and their placement on the farm.

11. Mechanical vectors Transmission of disease through non living things that are belongings to humans such as Glasses Watch Mobiles Rings

12. Biological vectors Vermin are everywhere where poultry are. There is feed, places to hide and a suitable climate for multiplication. Control is very important; not just because of the direct damage, but perhaps especially because of the possibility of the carryover of micro-organisms.

13. Operation must have a written program to control of at least the following species: wild birds, mice and rats, flies, lice, mites, and fleas Pets are not allowed in the buffer zone or the clear area.

14. Main Components of a Good Biosecurity Program

15. Isolation Isolation refers to Time Distance Physical barriers

16. Time The time required between two connective flocks to prevent the transmission of pathogens. This is also called down time Under normal conditions two weeks is adequate for complete cleaning and disinfection of the poultry house.

17. Two main principles

18. Distance Distance refers to, the distance between farms or houses on a farm

19. Physical barriers Barriers are very effective at limiting the spread of pathogens. But for successful physical barriers you should know the source of disease causing agent and their modes of transmission.

20. Fecal to oral Spread of pathogens when feces of an infected birds or visitor ingested by a susceptible chicken. Fecal contamination of litter and water is common in chicken on the floor between chicken. Barrier : Cages limit this mode of spread because fecal material does not accumulate where other chicks can not consume it.

21. Aerosol Transmission of disease should be considered when determining the design of poultry houses and their placement on the farm . Barrier :The air intake of one poultry house should be located away from the outflow went of other house

22. Traffic and visitor control Traffic Control includes both the traffic onto your farm and the traffic patterns within the farm. It includes: Limit staff movements Avoid visitors Control site traffic Spray vehicles Adequate protective clothing BOOTS Hand washing Showers
