MYCOVAC-L®
Mycoplasma Gallisepticum Vaccine
Product Description
Mycovac-L is a live vaccine, prepared from the Merck Animal Health 6/85 strain of Mycoplasma gallisepticum in a freeze dried preparation sealed under vacuum. The 6/85 strain is unique in that it is highly immunogenic for chickens and non-pathogenic for turkeys, does not readily spread to adjacent houses of chickens and is biologically stable. This vaccine has been propagated under exacting standards. The immunizing capability of this vaccine has been proven by various procedures including the Master Seed Immunogenicity Test.

- Highly immunogenic, with very mild reaction
- Not pathogenic to turkeys
- Does not spread to adjacent chicken houses

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 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.
Coarse Spray Administration
FOR CHICKENS SIX WEEKS OF AGE OR OLDER
Calculate the water volume needed. For example, a machine which dispenses 21 ml to a box of 100 chickens – total volume for 2,000 doses is 420 ml of non-chlorinated water. For coarse spray in chicken houses, follow manufacturer’s direction for the particular spray machine. Add rehydrated vaccine and mix thoroughly.
