The document outlines the importance of vaccination in poultry to enhance immunity, prevent diseases, and improve flock health and production efficiency. It details various types of vaccines, including modified live, inactivated, and recombinant vaccines, and provides a specific vaccination schedule for chicks. Additionally, it describes the procedures for administering vaccines, especially for Gumboro disease, including preparation and administration instructions.

1. Vaccination

2. WHY DO WE VACCINATE?
 To enhance the immunization of the chicks.
 Prevent from many contagious & deadly
diseases.
 Improve the flock health
 Improve the production efficiency

3. HOW DO VACCINES WORK?
 Vaccines contain different types of antigens.
 Depending on the type of antigen in the
vaccine, antibodies were created by immune
system of the bird
 Created antibodies fight against the causal
antigen

4. VACCINES & VACCINATION
Poultry vaccines come in 3 forms:-
I. Modified/ Live vaccines
 Strains that are naturally or genetically modified
II. Inactivated/ Killed vaccines
 Whole viruses or bacteria inactivated during production
 Supply as injectable form
III. Recombinant vaccines
 Use live viruses or bacteria as a vector to transport the
gene coding

6. Spray vaccination
Eye drop vaccination
Water vaccination Injectable vaccination

7. INJECTABLE VACCINES
Two major injection methods
I. Intramuscular (IM) – into the muscle
II. Subcutaneous (SC) – under the skin
Subcutaneous Intramuscular
Neck Breast
Inguinal fold Thigh
Leg
Wing
Tail head

8. HOW WE VACCINATE GUMBORO?
Before Vaccination
 Birds must be water restricted for approximately
one hour.
 Always administer the vaccine in the water early
in the morning.
 Waterers must be cleaned with suitable
disinfectants.

9. Vaccine Preparation
 Mix 200 doses with skim milk powder and
they apply to 10l of clean and boiled water.
Vaccine Administration
 Pour 500ml of vaccine mixture into the
drinkers of each replicate.

10. IF CHICK INFECTED BY INFECTIOUS BURSAL
DISEASE (IBD)
 Inflammation
 Subsequent atrophy of the bursa of fabricius
 Feathers around the vent are stained with
feces
 Ruffled feathers with droopy appearance
