Gumboro vaccine is a prophylactic regimen containing the intermediate strain of infectious bursal disease (IBD) virus. This vaccine is presented in freeze-dried form packed in vials and is generally well-tolerated by poultry birds.
- By well-tolerated, we mean the vaccine will not damage the bursa, will not impair the immune response, and will not cause significant vaccinal side effects.
- This vaccine protects against infectious bursal disease, a disease that causes morbidity and mortality in poultry birds.
- This product is the small-dose vial variety and can be 100- or 200-dose.
- Store this vaccine in a refrigerator or cold chain at 2⁰C up to 8⁰C.
Gumboro vaccine: Reconstitution
- Store the diluent in the refrigerator overnight to chill before use.
- Reconstitute by drawing a small quantity of diluent using a sterile syringe and then transferring this diluent into the freeze-dried vaccine vial.
- Allow the pellet to dissolve completely with diluent, gently shake the vaccine vial, and then transfer it to the diluent bottle.
- Rinse the vaccine vial twice with the diluent a similar manner.
- Reconstituted vaccine should be stored in ice and used completely within one hour.
- Ensure to follow strict aseptic techniques during reconstitution.
Administration of Gumboro vaccine
EYE DROP METHOD
- This method should be used for primary vaccination. Use reconstituted vaccine immediately.
- Hold the chick with one eye turned up. Take the vaccine mixture using a sterile syringe.
- Using blunt needle of 15 gauges or calibrated dropper, instil one drop into the eye per chick.
- Ensure that the vaccine drop is completely absorbed in the eye.
- Some people administer the vaccine with this method using the nasal opening. This is also an acceptable practice.
DRINKING WATER METHOD
- For drinking water method, before giving the vaccine, withhold the birds from drinking water for at least two hours. This ensures that the birds are thirsty and will eagerly consume the vaccine-containing water.
- Do not use a disinfectant in the drinking water for a period of 48 hours prior to and 24 hours after vaccination. If a chlorine pump is used, switch it off for the same period of time.
- The drinkers should be thoroughly cleaned before vaccination.
- Prepare the required volume of water that will be consumed by the chicken in 2 hours. This volume may however change according to the weather and environmental conditions.
