Bronchitis Vaccine (Mass. Type) Indications

These vaccines are recommended for the vaccination of healthy chickens as an aid in the prevention of bronchitis.

The frozen vaccine is recommended for use as a coarse spray in healthy one day old chickens.

The 5,000 dose size of the freeze-dried vaccine is recommended for the vaccination of healthy chickens seven days of age or older.

It is essential that the chickens be maintained under good environmental conditions, and that exposure to disease viruses be reduced as much as possible.

Dosage and Administration

Read directions carefully.

A. Frozen Vaccine: For one (1) day old chickens.

Preparation of Vaccine:

1. Dilute the vaccine only as directed, observing all precautions and warnings for handling.

2. Remove from the liquid nitrogen only the ampules that are going to be used immediately. Move quickly, but carefully.

3. Place the ampule(s) in a large, clean container of water at 68° to 86°F (20° to 30°C) to thaw ampule quickly. Thaw the entire contents. Gently swirl the ampule to disperse contents. Break ampule at its neck and quickly proceed as described below.

4. Mix the contents of the ampule with cool, non-chlorinated water using 10,000 doses of vaccine to 700 mL of water.

5. Use the vaccine mixture immediately as described below.

Use of Vaccine for Coarse Spray Administration: Coarse spray vaccination is recommended for healthy chickens at one day of age or older.

1. Each box of 100 chickens should receive approximately 7 mL of vaccine. The exact amount can be determined by spraying into a calibrated tube or container to arrive at the number of applications needed to deliver 7 mL of vaccine.

2. Take care to administer a full dose to each chicken.

3. Allow chicks to dry; avoid chilling.

B. Freeze-dried Vaccine (5,000 doses): For seven (7) day old chickens.

Drinking Water Vaccination - Pouring Application:

1. Do not open or mix the vaccine until ready to vaccinate.

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

3. Provide sufficient waterers so that all of the chickens can drink at one time. Shut off the water supply and allow the chickens to drink the troughs dry.

4. Raise the water troughs above chickens' heads. Clean and rinse the waterers thoroughly.

5. Withhold all water from the chickens for a minimum of two (2) hours in warm weather to four (4) hours in cool weather prior to vaccination to stimulate thirst. The water withdrawal time should be reduced if half-house brooding is in process.

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

Example:

10,000 chickens in cool weather x 3 gallons (11 L) = 30 gallons (114 L).

14,500 chickens in warm weather x 4 gallons (15 L) = 58 gallons (220 L).

7. Add one of the following to pouring water for vaccine distribution:

a. One (1) ounce (30 mL) of non-fat, dry milk per gallon (4 L) of water, or

b. Four (4) ounces (118 mL) of fresh skim milk per gallon (4 L) of water.

8. Prepare the vaccine concentrate as follows:

a. Prepare a container of milk/water figuring one (1) ounce (30 mL) of concentrate for one (1) gallon (4 L) of water to be used.

b. Add cool milk/water to the vial until the dried vaccine is dissolved. Add the vaccine to the container of milk/water to make the vaccine concentrate. Rinse the vaccine vial to remove all of the vaccine.

9. To make the vaccine solution, add one (1) ounce (30 mL) of concentrate for each gallon (4 L) of water needed.

10. Distribute the vaccine solution among waterers. Avoid direct sunlight.

11. Lower the water troughs and allow the birds to drink freely. Add the remaining vaccine solution to the troughs as the birds drink.

12. Do not provide any additional drinking water until all of the vaccine solution is consumed.

Drinking Water Vaccination - Proportioner Application: Several types of medicator/proportioners are commercially available. Set the proportioner to deliver one (1) ounce (30 mL) of vaccine concentrate per one (1) gallon (4 L) of water.

1. Do not open or mix the vaccine until ready to vaccinate.

2. Remove all medications, sanitizers and disinfectants from the proportioner 72 hours (three days) prior to vaccination.

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

4. Withhold all water from the chickens for a minimum of two (2) hours in warm weather to four (4) hours in cool weather prior to vaccination to stimulate thirst.

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

Example:

10,000 chickens in cool weather x 3 gallons (11 L) = 30 gallons (114 L).

14,500 chickens in warm weather x 4 gallons (15 L) = 58 gallons (220 L).

6. Prepare the vaccine concentrate as follows:

a. Add three (3) ounces (90 mL) of non-fat, dry milk per 16 ounces (473 mL) of cool water, or

b. Use undiluted, cool, fresh skim milk.

7. To make the vaccine solution, add one (1) ounce (30 mL) of concentrate for each gallon (4 L) of water needed.

8. Add the milk solution to the vial until the dried vaccine is dissolved. Rinse the vaccine vial to remove all of the vaccine.

9. Insert the proportioner hose into the vaccine concentrate and start the water flow. Continue until all of the concentrate has been consumed before changing the water supply to direct flow.

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

Coarse Spray Application: Coarse spray application is recommended for revaccination only and not as a primary vaccination. Use a sprayer delivering a coarse spray pattern to dispense the rehydrated vaccine quickly and evenly throughout a house of chickens.

1. Prior to spraying, reduce the air flow by raising curtains or stopping fans. Air movement should be limited for 15 minutes following vaccination.

2. Fill the vaccine container with cool, distilled, de-ionized water.

3. Pour the reconstituted vaccine into a clean container and add five (5) ounces (150 mL) of cool water for each 1,000 chickens to be vaccinated.

4. Place the vaccine solution into a spray canister and walk through the house spraying at the rate of 1,000 chickens per minute. Direct the spray directly above the heads of the chickens.

5. Avoid direct contact with the vaccine solution. Wear goggles and a face mask while spraying.

6. Do not use vaccinating equipment for any other purpose.

Precaution(s): A. Storage Conditions for Frozen Vaccine:

Ampules: Store in a liquid nitrogen container.

Diluent: Store at room temperature.

Liquid Nitrogen Container: Carefully observe all liquid nitrogen precautions, including wearing eye protection and gloves. Store in a cool, well-ventilated area. Check the liquid nitrogen level daily. Keep the container away from incubator intakes and chicken boxes. Do not hold ampule toward face when removing from a liquid nitrogen container. Never refreeze a vaccine ampule after thawing.

Liquid Nitrogen Precautions: The liquid nitrogen containers and vaccines should be handled only by properly trained personnel. These persons should be familiar with the Union Carbide publication “Precautions and Safe Practices - Liquid Atmospheric Gasses”, form #9888.

Liquid nitrogen is extremely cold. Accidental contact with the skin or eyes can cause serious frostbite. Protect the eyes with goggles or a face shield. Wear gloves and long sleeves when removing and handling frozen ampules or when adding liquid nitrogen to the container.

Storage and handling of liquid nitrogen containers should be in a well-ventilated area. Excessive amounts of nitrogen reduce the concentration of oxygen in the air of an unventilated space and can cause asphyxiation. If drowsiness occurs, get fresh air quickly and ventilate the entire area. If a person becomes groggy or loses consciousness while working with liquid nitrogen, get the person to a well-ventilated area immediately. If breathing has stopped, begin artificial respiration. Call a physician immediately.

Use the entire contents when first opened.

Burn the container and all unused contents.

B. Storage Conditions for Freeze-dried Vaccine:

Store the freeze-dried vaccine at 35-45°F (2-7°C). Do not freeze.
