HAN-IB 4/91 Vaccine (Infectious Bronchitis)

Han-IB 4/91 is recommended for vaccination against IBV.

Method of administration: Ocular-nasal, oral and via drinking water.

▪ Ocular-nasal: Reconstitute the vaccine with cooled accompanying diluent. The vaccine is dissolved in diluents on purpose to obtain each dose with volume equivalent 1 drop.

▪ Spray method: For day old chicks use 0.2–0.3 liter for 1000 chicks and for older chickens use 0.5–1 liter for 1000 birds. The vaccine medicated water should be sprayed evenly over the correct number of birds, at a distance of 40 cm to 50 cm.

▪ Drinking water: Dissolve vaccine in water for 1000 chicks according to the table below:
 

Age of chicken	7-days of age	14-days of age	28-days of age	> 56-days of age
Layers	4 liters	10 liters	25 liters	40 liters
Broilers	8 liters	20 liters	44 liters	-

Note:
- Ensure that the chickens are thirsty by withholding normal water supply from the chickens for 1–2 hours before vaccinating.
- Ensure that there are enough drinkers available to ensure that all chickens have access to the vaccine-medicated water within 1 hour to 2 hours.

Storage

Keep at 2–8°C. Do not freeze. Use reconstituted vaccine within 2 hours.
