POULTRY PRODUCTION and Flock Health Management.pdf

Poultry vaccination is a critical component in the management and health maintenance of poultry flocks. It involves the administration of vaccines to chickens, turkeys, ducks, and other avian species to protect them from infectious diseases. Effective vaccination programs help prevent outbreaks of diseases, ensuring the health and productivity of the poultry, which is essential for food security and economic stability.

3. Vaccination Tips

4. 1. Purchase recommended
strain/type of vaccines from
reliable sources.

5. 2. Keep vaccines cool at all
times. They are best stored in
the refrigerator at 4C where
they
are kept cold, but not subjected
to freezing and thawing.

6. 3. Put vaccines in an icebox
during transport.

7. 4. Take note of the expiry date, which is
stamped on each packet of vaccine.
Vaccines lose potency slowly even when
stored under ideal conditions. Vaccines
should be purchased as required, stored
properly, and used within the expiry
period.

8. 5. Follow strictly vaccination schedule and
proper use of vaccines as indicated by the
manufacturer.

9. 6. Administer the correct dose.
Dosages should not be decreased
nor increased unnecessarily.

10. 7. Vaccinate healthy chickens
only. Do not vaccinate the flock
when there is an outbreak of
disease in the farm (e.g.,
infectious coryza, coccidiosis,
CRD, etc).

11. 8. Administer live vaccines within
1 hour after reconstitution. Keep
vaccines cool during
vaccination time.

12. 9. Avoid unnecessary stress during
vaccination. Anti-stress supplement may
be given via the drinking water at least 2
days before and 3 days after vaccination
that requires individual handling of
chickens (e.g, intraocular or intranasal
route of administration).

13. 10. Destroy unused reconstituted
live vaccines. Burn or bury empty
vials/bottles and leftover live
reconstituted vaccines.

14. 11. Check or monitor the immune response
to NCD or IBD live vaccines by using the
hemagglutination-inhibition (HI) test of
ELISA, 10-14 days after each NCD or IBD
vaccination. These tests are conducted in
most diagnostic laboratories. Revaccinate
flock if the protection or antibody titer is
low.

15. Vaccination Failure

16. Occasionally, vaccines may
fail to immunize or adequately
protect chickens from field
pathogens due to the following
reasons:

17. 1. Administration of vaccines
that do not contain the
appropriate strain or
serotypes of the
pathogen causing the disease

18. 2. Decreased vaccine potency
due to improper storage
and/or handling, or use of
expired vaccines

19. 3. Improper method of
administering the vaccine or
giving of inadequate dosage

20. 4. Presence of high levels of
maternal antibody that
interferes with the
immunization process,
particularly in very young
chicks

21. 5. Stress, incomplete development of
immuno-competence, poor nutrition,
mycotoxin, presence of concurrent
immunosuppressive infections (e.g., IBD,
CRD, coccidiosis) that tend to cause less
effective or incomplete immune
responsiveness to vaccines
