Vaccination of laying hens is a fundamental element to guarantee their health and productivity. A well-structured vaccination programme helps prevent diseases that can affect poultry performance. Here is a practical guide for Ivorian farmers on the vaccination programme for laying hens, from day 1 until the start of laying.
1. Vaccination at day 1: Early protection
From birth, it is crucial to vaccinate the day-old chicks against Marek's disease. This viral disease is highly contagious and can lead to significant losses. Vaccination should be carried out on the first day of life to ensure optimal protection.
2. Vaccination at 7 days: Infectious bronchitis
At 7 days old, the chicks should be vaccinated against infectious bronchitis, a respiratory disease that can severely affect the growth and production of hens. This vaccination helps to strengthen their immune system from the beginning of their lives.
3. Vaccination at 14 days: Newcastle disease
At 14 days, it is recommended to administer a vaccine against Newcastle disease, which is another widely prevalent viral disease. This vaccination is essential to protect poultry against severe symptoms and economic losses.
4. Vaccination at 21 days: Infectious coryza
At this age, the hens should also be vaccinated against infectious coryza. This bacterial disease can lead to respiratory problems and affect the productivity of layers. Preventive vaccination is therefore necessary.
5. Vaccination at 28 days: Boosters and other vaccines
At 28 days, it is advisable to give a booster for Newcastle disease. Additionally, depending on the sanitary conditions and risks present in your area, you may consider other vaccines such as that for infectious laryngotracheitis.
6. Vaccination as laying approaches: Preparation for production
About two weeks before the start of laying, it is important to vaccinate the hens against salmonellosis. This vaccination is crucial to ensure food safety and the quality of the eggs produced.
Practical tips for successful vaccination
- Follow a strict vaccination schedule: Ensure that you adhere to the recommended ages and intervals for vaccination.
- Use quality vaccines: Choose reliable vaccines that are suitable for local conditions.
- Monitor the health of the poultry: Observe the birds closely for any potential side effects or signs of disease.
- Train the staff: Ensure that anyone involved in vaccination is well trained in vaccine administration techniques.
Conclusion
Vaccination is an essential step to ensure the health and productivity of your laying hens. By following this vaccination programme, you will help reduce the risks of diseases and optimise egg production. Do not hesitate to inquire about vaccine prices and consult veterinarians for advice specific to your farm. Take action now to ensure the success of your poultry farming in Côte d'Ivoire!
