Live lyophilized vaccine against avian infectious bursal disease
Active substance: Avian infectious bursal disease virus (BIA), I-93 strain with minimum titer of 103 DIE50 and maximum titer of 106 DIE50 / dose.
Other ingredients: peptone, lactose.
It is intended for fowl vaccination against death, clinical symptoms and/or lesions specific to avian infectious bursal disease in areas and farms with medium infective pressure.
The immunity induced by BIAROMVAC I-93 takes place 2 weeks after administration and lasts for 65 weeks.
The vaccine does not cause postvaccinal reactions.
DOSAGE FOR EACH SPECIES, ROUTE(S) AND METHOD OF ADMINISTRATION
- by oculo-conjunctival or nasal route: reconstitute each vaccine dose in 0.1 ml diluter (in order to administer the recommended dose, check as to provide 20 drops/ml from the reconstituted vaccine); apply a drop in each eye or two drops in the mouth.
- by intramuscular route: the dose is 0.2 ml/chicken
Mass administration, in the drinking water: reconstitute each vaccine dose in 10-40 ml drinking water depending on the age and breed of chickens. The drinking water must be clear and disinfectant-free (especially chloride). To immunize 1000 chickens, reconstitute the vaccine (1 vial x 1000 doses) and administer in 20-30 liters of drinking water. To protect the vaccine virus, add 0.2-0.5% powder milk in the water.
The age when chickens can be vaccinated depends on the amount of maternal antibodies based on the determination of the immunological status and this is why the vaccination is carried out according to the chicken category and the way the breeding flocks have been vaccinated. If the parents have been vaccinated with live vaccines against BIA, vaccinate the broilers at the age of 7-14 days, and the replacement youth at the age of 14-21 days. If the parents have been vaccinated with killed vaccines against BIA, vaccinate the broilers at the age of 7-14 days, and the replacement youth at the age of 21-28 days.
ADVICE ON CORRECT ADMINISTRATION
2-3 hours hydrous diet according to the season and an appropriate watering system are recommended. Use the reconstituted vaccine at 3 hours interval. The appropriate vaccination period depends on the epizootic condition of the flocks and area where fowls are reared, evaluated under the direct coordination of the veterinarian providing the sanitary veterinary supervision based on the determination of the immunological status. Carry out one, two or more booster vaccinations according to these results. The correlation between the vaccination date and titer of antibodies against BIA virus and the infective pressure in the farm provide good immunity (specific protection).
