Vaccination of laying hens is a crucial step to ensure their well-being and maximise their egg production. A well-structured vaccination programme helps prevent many diseases that can affect the health of poultry and, consequently, the profitability of your farming. Here is an overview of the vaccinations to consider, from day 1 until the start of laying.
Days 1 to 7: The first vaccinations
Upon their arrival at the hatchery, the chicks must be protected against certain diseases. On day 1, it is recommended to vaccinate against Marek's disease, a common viral infection. This vaccine is administered by subcutaneous injection.
On day 7, vaccination against infectious bronchitis is often advised. This virus can cause respiratory problems and affect the growth of the birds. There are different strains of vaccines, and it is important to choose one that is suitable for your region and the circulating strains.
Week 3: Strengthening immune defences
At three weeks of age, it is advisable to vaccinate the chicks against Newcastle disease. This viral disease is highly contagious and can cause significant losses. Vaccination is generally done intranasally or by drops in the water.
Week 6: Additional vaccines
At six weeks, a booster vaccination against infectious bronchitis may be carried out, depending on the chosen vaccination programme. Additionally, it is possible to introduce a vaccine against infectious coryza, which can affect the respiratory health of poultry.
Weeks 8 to 12: Preparation for laying
About a month before the start of laying, it is essential to vaccinate the hens against salmonellosis. This bacterial disease can be transmitted to humans through the consumption of contaminated eggs. Vaccination is generally done by injection.
Week 16: Final vaccinations
Before the start of laying, vaccination against avian influenza may be considered, especially if you are in a high-risk area. This helps protect your farm against potential outbreaks.
