General Recommendations

Vaccination is an important way of prevent-

ing diseases. Different regional epidemic situ-

ations require suitably adapted vaccination

programmes. Therefore, please be guided, by

the advice of your local veterinarian and poul-

try health service. Only healthy flocks should

be vaccinated. Check the expiration date of

the vaccine. The vaccine must not be used

after this date. Keep records of all vaccinations

and vaccine serial numbers.

Drinking Water Vaccinations

are not la-

bour intensive but must be carried out with

the greatest care to be effective. The water

used for preparing the vaccine solution must

not contain any disinfectants. During the

growing period, the birds should be with-

out water for approximately 2 hours prior

to vaccination. During hot weather reduce

Special Recommendations

Mycoplasmosis Vaccinations

are only

advisable if the farm cannot be kept free

of mycoplasmosis. Infections with virulent

mycoplasma species during the produc-

tion period lead to performance depression.

The best performance is achieved by flocks

which are kept free of mycoplasmosis and

are not vaccinated.

Vaccination against Coccidiosis

is the

most reliable method to develop immunity

against this disease. Never use coccidiostats

in the feed when pullets are vaccinated.

Applying Vitamins

in the first two to three

days after vaccination can help to reduce

stress and prevent undesired reactions. To

what extent depends on the specific situa-

tion on each farm.
