Description

This vaccine contains a live virus vaccine containing a carefully selected strain of bursal disease virus grown in chicken embryos and combined with stabilizing agents. The product is supplied as a lyophilized vaccine contained in sealed vials.

Bursa-Vac 51 Indications

For use in chickens as an aid in preventing infectious bursal disease at two weeks of age or older by drinking water.

Vaccination Programs

Many factors must be considered in determining the proper vaccination program for a particular farm or poultry operation. To be fully effective, the vaccine must be administered to healthy receptive chickens held in a proper environment under good management. In addition, the response may be modified by the age of the chickens and their immune status. Seldom does one vaccination under field conditions produce complete protection for all individuals in a given flock. The amount of protection required will vary with the type of operation and the degree of exposure that a flock is likely to encounter. For these reasons a program of periodic revaccination may be required.

When To Vaccinate

Vaccinate healthy chickens at two weeks of age or older by drinking water. Good management practices should be followed to reduce exposure of birds to virulent infectious bursal disease virus during the first weeks of life.

Precautions

Only Vaccinate Healthy Chickens

Consult your poultry pathologist for further recommendations based on conditions existing in your area at any given time.

Chickens should not be placed on contaminated premises. Exposure should be avoided immediately after vaccination, because it takes up to 10 days to develop resistance.

All susceptible chickens on the same premises should be vaccinated at the same time. If this is not possible, then strict isolation and separate caretakers should be employed lot non-vaccinated units. Efforts should be taken to reduce stress conditions at the time the vaccine is administered.

Warning

Care should be exercised to prevent contaminating your hands, eyes and clothing with the vaccine.

Preparation Of The Vaccine

Do Not Open And Mix The Vaccine Until Ready To Begin Vaccination.

Use Vaccine Immediately After Mixing.

Assemble the vaccine and equipment needed to vaccinate the entire flock at one time.

Drinking Water Administration

Drinking water for vaccination should be mixed with powdered milk to prevent inactivation from chlorine or other water additives and also to stabilize the vaccine virus. The powdered milk should be added to the water at the rate of 3 grams per 11 liters (one heaped teaspoon per 3 U.S. gallons or 2.5 Imp. Gallons); or 90 grams per 300 liters (one heaped cupful per 80 U.S. gallons or 66 Imp. Gallons).

1. Do not open and mix the vaccine until ready for use.

2. Remove the tear-off aluminum seal from the vaccine vial without disturbing the stopper.

3. Remove the rubber stopper from the vaccine vial and rehydrate the vaccine by filling the vial about half-full with clean non-chlorinated tap water to which powdered milk has been added.

4. Holding vial submerged in a pail of water or under a running stream of water, lift the lip of the rubber stopper so that the water (milk added) is pulled into the vial.

5. Reseat the stopper and shake the vial to thoroughly dissolve the vaccine.

Drinking Water Administration

FOR CHICKENS 2 WEEKS OF AGE OR OLDER

Withhold water for a couple of hours before vaccinating so the birds are thirsty. Thoroughly clean and rinse all watering containers so that no residual disinfectants remain. Dilute the vaccine immediately before use with cool, clean, nonchlorinated water (milk added). Pour the dissolved vaccine material into the following amounts of water and mix thoroughly.

Distribute diluted vaccine so that all birds 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.
