Tenosynovitis Vaccine

Modified Live Virus

ReoGuard L Indications

This vaccine contains the mild 1133 strain of avian reovirus. It is recommended for the vaccination of healthy chickens two weeks of age or older by drinking water as an aid in the prevention of tenosynovitis (viral arthritis). It is essential that the chickens be maintained under good environmental conditions and that exposure to disease viruses be reduced as much as possible.

Store vaccine at 2-7°C (35-45°F). Do not freeze. Do not vaccinate within 21 days before slaughter. Use entire vial contents when first opened. Burn this container and all unused contents. Contains streptomycin sulfate and penicillin as bacteriostatic agents and amphotericin B as a fungistatic agent.

Drinking Water Vaccination Using Pouring Application

Drinking water vaccination is recommended for healthy chickens two weeks of age or older.

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 29 g (one ounce) of non-fat dry milk per 3.8 liters (US gallon) of non-chlorinated water, or should contain milk product based stabilizer prepared according to the manufacturer’s instructions.

7. Reconstitute the vaccine in 11 liters (3 US gallons) of milk-water during cool weather or 15 liters (4 US gallons) 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 two weeks of age or older. Several types of medicator/proportioners are commercially available. Set proportioner to deliver 30 mL (one ounce) of vaccine concentrate per 3.8 liters (US gallon) 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 11 liters (3 US gallons) per 1,000 chickens in cool weather and 15 liters (4 US gallons) 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

5,000 chickens in cool weather x 11 liters (3 US gallons) = 55 liters (15 US gallons).

5,000 chickens in warm weather x 15 liters (4 US gallons) = 75 liters (20 US gallons).

6. Prepare vaccine stock solution as follows:

a. Determine the quantity of vaccine concentrate required by multiplying 30 mL (one ounce) x multiples of 3.8 liters (US gallons) of water needed for vaccine/drinking water.

Example

For 5,000 chickens: 15 volumes of 3.8 liters (1 US gallon) x 30 mL (1 ounce) = 450 mL (15 ounces).

b. Add 85 g (3 ounces) of non-fat dry milk per 480 mL (16 ounces) of cool water, or use a commercial milk product based stabilizer according to the manufacturer’s instructions. For 5,000 chickens add 75 g (2.5 ounces) non-fat dry milk to the 450 mL (15 ounces) of water.

c. Reconstitute the lyophilized 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.
