DIRECTIONS FOR USE – USE ONLY AS DIRECTED
WHEN TO VACCINATE
Vaccinate 18 to 19 day old embryonated chicken eggs by the in ovo route using an in ovo system or subcutaneously at 1 day of age or by drinking water at 1 week or older. Good management practices should be followed to reduce exposure of chickens to virulent infectious bursal disease (Gumboro) virus during the first few weeks of life.
PREPARATION OF THE VACCINE
In ovo and subcutaneous routes of administration
- Do not open and mix the vaccine until ready for use.
- Open only 1 vial at a time and use entire contents within 2 hours.
- Remove the tear-off aluminium seal on the vaccine vial to expose the rubber stopper. Using a sterile needle and 5 mℓ or 10 mℓ syringe, remove a small amount (5 mℓ) of the diluent from the diluent bottle and transfer this to the vaccine vial. The vacuum in the vaccine vial will rapidly pull in the diluent. Release the vacuum remaining in the vial.
- Shake the vaccine vial with transferred diluent to rehydrate the vaccine.
- Using the same sterile needle and syringe, completely transfer the rehydrated vaccine to the remaining diluent in the diluent bottle. Rinse syringe and vaccine vial by withdrawing additional diluent and repeating the process.
- Shake final rehydrated vaccine for 20 to 30 seconds to mix thoroughly.
- The vaccine is now ready for use.
Drinking water method
- Assemble the vaccine and equipment needed to vaccinate the entire flock at one time.
- Do not open and mix the vaccine until ready for use.
- Remove the tear-off aluminium seal from the vaccine vial without disturbing the rubber stopper.
- Use cool, clean, non-chlorinated water.
- Holding the vial submerged in a bucket of water or under a running stream of water, lift the lip of the rubber stopper so that the water is sucked into the vial.
- Reseat the stopper and shake the vial to thoroughly dissolve the vaccine.
HOW TO VACCINATE
- In ovo route of administration
- Follow the in ovo system operator’s manual before attempting any in ovo vaccination.
- Sanitise the in ovo system according to the operator’s manual.
- The in ovo system should be calibrated accurately to deliver 0,05 mℓ into each embryonated egg.
- Subcutaneous route of administration
- Insert a filling tube (large, sharpened transfer tube) into the vaccine vial.
- Connect the filling tube by means of rubber or plastic tubing to an automatic vaccinator fitted with a 22 gauge, ½ inch needle.
- The automatic vaccinator should be calibrated ahead of time to accurately deliver 0,2 mℓ.
- Drinking water method
- Do not mix Univax-BD® into the drinking water until ready for use.
- Withhold water for 1 to 2 hours depending on the ambient temperature before vaccinating to ensure that chickens are thirsty.
- Thoroughly clean and rinse all watering containers so that no residual disinfectants remain.
- Dilute Univax-BD® immediately before use with cool, clean, non-chlorinated water.
- Pour the dissolved vaccine material into the following amounts of water and mix thoroughly;
Each 1 000 chickens:
1 week 6,5 ℓ
2 to 4 weeks 10 ℓ
4 to 8 weeks 20 ℓ
Over 8 weeks 40 ℓ
- Distribute diluted vaccine so that all chickens are able to drink within a 1 hour period and do not add any more water until the vaccine is consumed.
- Avoid placing water in direct sunlight.
- Use only as indicated.
