COMPOSITION
1 dose of vaccine contains: not less than 1500 PFU
TARGET SPECIES
Poultry.
PROPERTIES
BIO-MAREK HVT is prepared using the FC-126 strain of Turkey Herpesvirus (HVT), cultured on fibroblasts tissue-cultures obtained from SPF embryonated eggs.
The viral suspension obtained from the cell by sound waves in a proper stabilizer, is freeze-dried and vacuum-sealed.
The freeze-dried vaccine induces a high degree of immunity, about the same as or even higher than that obtained by vaccine with cell-associated virus offering, at the same time, more practical utilization.
Only one vaccination, properly performed in the very first days of life, is sufficient to protect the animal.
Immunity reaches a significant level 15 days after inoculation of the vaccine, and it is complete after 20-25 days. The vaccination results are positively influenced if chicks are placed in a clean and disinfected environment and, obviously, kept out of contact with older animals during the first 2-3 weeks of life, in order to avoid early exposure to the Marek’s disease virus.
INDICATIONS
Prophylaxis of Marek’s disease.
ADMINISTRATION
IM.
DOSAGE
Put a small quantity of diluent (4-5 ml) into the vial containing the freeze-dried matter by means of a sterile syringe; once the contents are completely dissolved, pour it into the diluent vial; shake the vial carefully, then the vaccine is ready for use. BIO-MAREK HVT is inoculated only once, at a dose of 0.2 ml per animal, by intramuscular administration, preferably in the leg, using an automatic syringe. The recommended age for inoculation is 1-2 days.
NOTE
Once the vaccine has been diluted, it must be used within 2 hours.
The vaccine and diluent vial must be burned or disinfected after use.
