    Spray Administration:

    1. Remove seal and stopper. Half fill vial with cool distilled water. Replace stopper and shake until dissolved.
    2. Pour rehydrated vaccine into a clean container and add cool distilled water to dilute the vaccine as indicated for your specific coarse spray vaccination machine. For example, use a total of 500 mL of water per 5,000 doses of vaccine. Mix thoroughly.
    3. Administer at a rate of 1 dose of prepared vaccine per bird.

    Drinking Water Administration:

    1. Discontinue use of medications or sanitizing agents (such as chlorine) in the drinking water 24 hours before vaccinating. Do not resume use for 24 hours following vaccination.
    2. Provide enough waterers so two-thirds of the birds may drink at one time. Scrub waterers with fresh, clean, nonchlorinated water and drain dry. Do not give vaccine water through medication tanks.
    3. Turn off automatic waterers 2 to 4 hours before vaccinating so that the only available water is the vaccine water. Do not deprive birds of water in extremely hot weather.
    4. Remove seal and stopper. Half fill with clean, cool nonchlorinated water. Replace stopper and shake until dissolved.
    5. Use a clean container two-thirds filled with cool, clean, nonchlorinated water. Add dried milk at a rate of 1 ounce per 2.5 gallons.
    6. Add the rehydrated vaccine. Stir thoroughly and add water to make final mixture at a rate of 5,000 doses per 12.5 gallons.
    7. Give 1 dose of vaccine per bird, distributing the final volume of vaccine water evenly among the clean waterers. Do not place the waterers in direct sunlight.
    8. Resume regular water administration only after all the vaccine water has been consumed.
