Broiler Vaccination Schedule and Procedures

Broiler Vaccination Schedule and Procedures


A well-designed broiler vaccination program is crucial for protecting broilers from common poultry diseases and ensuring their long-term health and productivity. Vaccination plays a vital role in preventing disease outbreaks and reducing economic losses in broiler farming. In this article, we will discuss the importance of broiler vaccination, provide a general vaccination schedule, and outline key procedures for successful vaccination.

Importance of Vaccination

Vaccination is a proactive measure to safeguard broilers against infectious diseases. By vaccinating broilers, farmers can:

  • Reduce the risk of disease outbreaks.
  • Minimize mortality rates.
  • Improve flock performance and productivity.
  • Enhance the overall profitability of the broiler operation.
  • Vaccines stimulate the broilers’ immune system to develop immunity against specific pathogens, providing protection against diseases that can significantly impact broiler health and welfare.

General Vaccination Schedule

The following is a general broiler vaccination schedule. However, it is essential to consult with a veterinarian and consider regional disease prevalence, flock history, and specific vaccine recommendations:

1. Newcastle Disease Vaccine

Newcastle disease is a highly contagious viral disease that affects poultry, including broilers. Vaccinate broilers against Newcastle disease via eye drop, drinking water, or spray vaccination between 7 to 10 days of age.

2. Infectious Bronchitis Vaccine

Infectious bronchitis is a respiratory disease that can affect broilers. Vaccinate broilers against infectious bronchitis using eye drop, drinking water, or spray vaccination at around 14 days of age.

3. Gumboro (Infectious Bursal Disease) Vaccine

Gumboro, or infectious bursal disease, is an immunosuppressive viral disease that can cause severe economic losses. Vaccinate broilers against Gumboro using drinking water, spray, or eye drop vaccination at approximately 18 to 21 days of age.

4. Avian Influenza Vaccine

Avian influenza is a highly contagious viral disease that poses a threat to broilers and the poultry industry. Vaccination against avian influenza should be carried out according to regional disease risk and vaccination recommendations. Consult with a veterinarian to determine the appropriate timing and method of avian influenza vaccination.

Vaccination Procedures

Proper vaccination procedures are critical to ensure vaccine efficacy and broiler health. Follow these essential steps for successful vaccination:

1. Vaccine Storage and Handling

Store vaccines at the recommended temperature and protect them from direct sunlight and extreme temperatures. Follow the manufacturer’s instructions for vaccine storage and handling to maintain vaccine viability. Use vaccines before their expiration dates and avoid using damaged or expired vaccines.

2. Vaccine Preparation

Prepare vaccines according to the manufacturer’s instructions. Dilute vaccines with the appropriate diluent or mixing solution as recommended. Use sterile equipment and ensure proper hygiene during vaccine preparation to prevent contamination.

3. Vaccine Administration

Administer vaccines using the appropriate method, such as subcutaneous injection, eye drops, drinking water, or spray vaccination. Follow the recommended dosage and administration technique for each specific vaccine. Ensure proper needle size, vaccination equipment, and technique to minimize stress and discomfort to the broilers.

4. Record-Keeping

Maintain accurate vaccination records, including the type of vaccine, date of administration, dosage, and the identification of the flock or group vaccinated. Proper record-keeping helps track vaccination history, monitor flock health, and comply with regulatory requirements.

5. Post-Vaccination Monitoring

Monitor broilers after vaccination to assess their response and detect any adverse reactions. Observe broiler behavior, feed consumption, and overall health status. Promptly address any concerns or unusual reactions by seeking veterinary advice.


A well-planned broiler vaccination program is a critical component of broiler health management. By adhering to a comprehensive vaccination schedule and following proper vaccination procedures, farmers can protect broilers from infectious diseases and promote their long-term health and productivity. Consultation with a veterinarian, regional disease considerations, and proper record-keeping contribute to the success of broiler vaccination programs.
