INDICATIONS

Prevention of the Infectious Bronchitis. The immunity installs after 21 days from the inoculations and lasts for 45 days. The further inoculations are determined by the category of poultry, by the epizootological situation of the farm and by its immunization program.

 

POSOLOGY, ADMINISTRATION WAY AND MODE

Intake 1 dose/ poultry.

The vaccine may be administered starting from the age of 1 day, after which it is made the maintenance inoculation, according to the prevention program of the farm.

Oculo-nasal:

Once the lyophilized tablet is dissolved in the included solvent (sterilized purified water), take a drop of vaccine (0,33 ml) per poultry, in the eyes or the nasal slit, use a standard quickloader (usually 30 ml per 1000 doses).

Oral way:

Dissolve the lyophilized tablet by filling to half of the phial where it is with water, agitate and pour in an adequate recipient with drinking water, which may be consumed within a half an hour or maximum one hour, taking into account the following:

 

 

Age of the poultry

Approximate quantity of water

For 1000 poultry

1-3 weeks 5-10 liters
4 – 9 weeks 12 – 23 liters
10 – 16 weeks 27 – 37 liters

 

 

Powdering:

The necessary quantity of water depends on the type of host, on the number of poultry, age, aeration, temperature and the used equipment. The quantity varies between 250 and 1,000 ml/1,000 poultry.

General rule: as the particle is smaller, the viral suspension will reach deeper in the respiratory tract.

  • For the first inoculation, use apparatuses that generate particles with the size > 50 µm.
  • From 3, 4 weeks, the size of particles must be < 50 µm.

As diluting agent, it is used the clean drinking water, entirely lacked of disinfecting substances and especially chlorine.

  • Powder on all the poultry.
  • The aeration must be stopped both during the inoculation and 20-30 min. after it.
  • Decrease the light intensity to appease the poultry.
  • Use a face and eyes protection.
  • The equipment must only be used on inoculation and must not include traces of disinfectants and detergents.

 

For the inoculation with aerosols, it must only be used a tested equipment. The following table provides a few examples:

 

  Inoculation with big particles Inoculation with fine particles
Size of the drop > 50 µm < 50 µm
Pressure 500-600 ml/min; 2-3 bar 50 ml/min
Volume/ 1000 poultry 500-1000 ml 100-200 ml
Period/ 1000 poultry 1-2 min 5 min

 

For the chickens grown on the bed, the vaccine is reconstituted in a volume of 1,5 – 2 ml/dose.
