Vaccination is the backbone of poultry disease prevention. The diseases that cause the heaviest losses in Kenya — Newcastle disease, Gumboro and fowl typhoid — are largely preventable with a timely vaccination programme.
This article outlines typical schedules for broilers and layers. Always confirm the exact programme with your local veterinarian, as it varies with disease pressure in your area.
Why vaccinate?
Vaccines train the bird's immune system to resist specific diseases before exposure. In high-density poultry areas, an unvaccinated flock can be wiped out by a single Newcastle disease outbreak.
Vaccination is far cheaper than treatment — and for viral diseases like Newcastle and Gumboro, there is no cure once birds are infected.
Typical broiler schedule
Because broilers live only 6 weeks, their programme is short and focused on the highest-risk viral diseases.
- Day 1 (often at hatchery): Marek's disease
- Day 7: Newcastle disease (NCD) + Infectious Bronchitis
- Day 14: Gumboro (IBD)
- Day 18–21: Gumboro booster (per local advice)
- Day 21: Newcastle booster (per local advice)
Typical layer/pullet schedule
Layers live much longer, so they receive additional vaccines and boosters to protect them through the laying period, including fowl typhoid and fowl pox.
- Day 1: Marek's disease
- Day 7 & repeat: Newcastle + Infectious Bronchitis
- Day 14 & 21: Gumboro and booster
- Week 6–8: Fowl typhoid and fowl pox
- Before lay (~16 weeks): Newcastle booster
How to administer vaccines
Vaccines are given by eye/nose drop, drinking water, injection or wing-web stab depending on the product. Handle them carefully — keep them cold, use clean equipment, and use drinking-water vaccines within a couple of hours.
When vaccinating via water, withhold water briefly beforehand so birds drink the vaccinated water promptly, and avoid chlorinated or treated water that can inactivate the vaccine.
Frequently Asked Questions
What is the most important poultry vaccine in Kenya?
Newcastle disease vaccine is the most critical, as Newcastle is endemic and causes the heaviest losses. It is given early and boosted regularly.
Can I vaccinate poultry myself?
Many farmers administer water and eye-drop vaccines themselves, but it is best to get training and confirm the schedule with a veterinarian, especially for injectable vaccines.
