precautions

1. Birds should be vaccinated before they reach maturity since bronchitis virus may cause permanent damage to the reproductive tract of mature birds, resulting in eggs with poor interior quality and shell texture.

2. Infectious bronchitis is highly contagious when non-vaccinated birds are kept in close contact with vaccinated birds during the period of respiratory signs. The vaccine should be used with caution around non-vaccinated laying birds.

3. Mix only the amount of vaccine to be used immediately and use promptly. Use all at one time and do not stretch the dosage.

4. This vaccine is composed of live viruses in a lyophilized preparation sealed under vacuum. Improper storage or handling of the vaccine may result in loss of potency.

5. For veterinary use only.

Intraocular Vaccination

The vaccine used for intraocular vaccination is accompanied by diluent and is recommended for the vaccination of healthy chickens four days of age or older using the 1,000 dose or 2,000 dose vial.

1. Reconstitute each 1,000 doses of vaccine with 30 ml of diluent.

a. Remove aluminum seal and rubber stopper from vaccine vial and diluent vial. Avoid contamination of stoppers and contents.

b. Add diluent to half-fill the vaccine vial. Replace stopper in vial and shake it so that all contents are dissolved.

c. Pour the reconstituted vaccine into the diluent container. Replace stopper in diluent container and shake.

d. Remove stopper and fit drop-dispenser tip into diluent container.

2. Holding the diluent container with the dropper tip down, gently press the sides, dropping one drop of vaccine on the bird's eye. Be sure the vaccine spreads over the eye before releasing the bird.

Drinking Water Vaccination Using Pouring Application

Drinking water revaccination is recommended for healthy chickens at least 21 days of age.

1. Remove all medications, sanitizers and disinfectants from the drinking water 72 hours (three days) prior to vaccination.

2. Provide sufficient waterers so that all the chickens can drink at one time. Shut off water supply and allow chickens to consume all the water in the lines.

3. Raise water lines above the chickens' heads. Clean and rinse the waterers thoroughly.

4. Withhold all water from the chickens for a minimum of two hours in warm weather to four hours in cool weather prior to vaccination to stimulate thirst. Withdrawal time should be reduced if half-house brooding is in process.

5. Do not open or mix vaccine until ready to vaccinate.

6. Drinking water for vaccine delivery should contain one ounce (29 gram) of non-fat dry milk per gallon (3.8 liters) of non-chlorinated water, or should contain milk product based stabilizer prepared according to the manufacturer's instructions.

7. Reconstitute the vaccine in 3 gallons (11 liters) of milk-water during cool weather or 4 gallons (15 liters) of milk-water during warm weather for each 1,000 doses.

8. Distribute vaccine solution among waterers. Avoid direct sunlight.

9. Lower waterers and allow the chickens to drink freely. Add the remaining vaccine solution to the water lines as the chickens drink.

10. Do not provide additional drinking water until all the vaccine is consumed.

Drinking Water Vaccination Using Proportioner Application

Drinking water vaccination is recommended for healthy chickens at least 21 days of age. Several types of mediator/proportioners are commercially available. Set proportioner to deliver one ounce (30 ml) of vaccine concentrate per one gallon (3.8 liters) of water.

1. Remove all medications, sanitizers and disinfectants from the drinking water 72 hours (three days) prior to vaccination.

2. Clean all containers, hoses and waterers prior to vaccination.

3. Withhold all water from the chickens for a minimum of two hours in warm weather to four hours in cool weather prior to vaccination to stimulate thirst. Withdrawal time should be reduced if half-house brooding is in process.

4. Do not open or mix vaccine until ready to vaccinate.

5. Calculate to supply vaccine solution at a rate of 3 gallons (11 liters) per 1,000 chickens in cool weather and 4 gallons (15 liters) per 1,000 chickens in warm weather. The age of the chickens should be considered when calculating water supply. Always use non-chlorinated water when vaccinating chickens.

Example

1,000 chickens in cool weather x 3 gallons (11 liters) = 3 gallons (11 liters). 1,000 chickens in warm weather x 4 gallons (15 liters) = 4 gallons (15 liters).

6. Prepare vaccine stock solution as follows:

a. Determine the quantity of vaccine concentrate required by multiplying one ounce (30 ml) x gallons of water needed for vaccine/drinking water.

Example

For 1,000 chickens: 3 gallons x 1 ounce (30 ml) = 3 ounces (90 ml).

b. Add 3 ounces (85 gm) of non-fat dry milk per 16 ounces (480 ml) of cool water, or use a commercial milk product based stabilizer according to the manufacturer's instructions. For 1,000 chickens add 0.5 ounces (16 gm) non-fat dry milk to the 3 ounces (90 ml) of water.

c. Reconstitute the dried vaccine with the milk solution. Rinse the vaccine vial to remove all the vaccine.

7. Insert proportioner hose into the vaccine stock solution and start water flow. Continue until all solution has been consumed before changing water supply to direct flow.

8. Do not medicate or use disinfectants for 24 hours after vaccination.

Precautions

Do not vaccinate diseased chickens. Vaccinate all chickens on the premises at one time. Administer a minimum of one dose per chicken. Avoid stress conditions during and following vaccination. Do not place chickens in contaminated facilities. Exposure to disease must be minimized as much as possible. For veterinary use only.
