Based on the ND titre levels, we have to vaccinate in regular intervals to the breeder flock will be safe for us to maintain the flock against ND

Incase of vaccine failure, when not certain about the potency of the vaccine

[Bello Bashir]

Yes 👍

[Hope Iloka]

The potency of the vaccine can be tested before use.

Repeating the Newcastle Disease (ND) vaccine in breeder birds can have several impacts on egg production, fertility, and hatchability:

1. Egg Production:

   • Positive Impact: Vaccination helps maintain the health of breeder birds, leading to consistent egg production.
   • Potential for Drop: If the timing of vaccination coincides with the production phase, there may be a temporary drop in egg production due to stress from the vaccination.

2. Fertility:

   • Improved Fertility: Healthy breeders with effective vaccination programs tend to have better fertility rates, as vaccination reduces the risk of ND, which can negatively affect reproductive performance.
   • Stress Effects: If vaccinations are not timed properly, they could stress birds and temporarily lower fertility.

3. Hatchability:

   • Enhanced Hatchability: Vaccinated breeder flocks are generally healthier, leading to improved hatchability rates as healthy eggs are more likely to develop into viable chicks.
   • Possible Risks: Excessive vaccination or poor management practices around vaccination timing may lead to reduced hatchability if it impacts the health of the hens or causes stress during critical laying periods.

Overall, a well-planned ND vaccination program is essential for maintaining the health of breeder birds, which ultimately supports optimal egg production, fertility, and hatchability.
