Vaccination Programs

Many factors must be considered in determining the vaccination program for a particular farm or poultry operation. To be fully effective, the vaccine must be administered to healthy receptive birds held in proper environment under good management. In addition, the response may be modified by the age of the birds and their immune status. Seldom does 1 vaccination under fi eld 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.

Method Of Vaccination

1. For in ovo administration: inoculate each 18-day-old chicken embryo with a full dose (0.05 ml or 0.1ml).
   For subcutaneous administration: inoculate each day-old chicken with a full dose (0.2 ml).
2. Use entire contents of diluent bag within 1 hour after mixing.
3. After reconstitution, the vaccine should be kept cool and gently agitated frequently.
