Newcastle - Infectious Bronchitis Disease Vaccine

  Bivalent inactivated oil emulsion vaccine for breeder hens to immunize against Newcastle - Avian Infectious Bronchitis Disease.


  • K Vac ND-IB is produced with high titering strain of Newcastle - Avian Infectious Bronchitis disease virus, derived from embryonated chicken's egg, suspended in a stable oil emulsion. A large amount of antigen is provided in a (1/2 ml) 0.5 ml dose.
  • Whereas there is very poor cross protection between the different bronchitis strains, this vaccine contains the Massachusetts strain of IB virus. These is the most serious and common strain that infect flocks.When injected, the oil emulsion controls the absorption of the virus and greatly enhances the development of high levels of immunity.


Each dose contains not less than a pre-inactivation titer of 109 EID50 of Newcastle disease virus and 106.9 EID50 of Avian Infectious Bronchitis disease virus.   


  • K Vac ND-IB has been developed for use in breeder hens to give broad protection against Newcastle disease and Avian Infectious Bronchitis disease. When injected, the vaccine produces a high level of circulating antibody (humoral immunity) which is maintained through out the production cycle.
  • It provides high level of immunity in the progeny. This is the only way to provide protection to the chick during the critical first few days of life.


  • K Vac ND-IB provides a broader range of IB protection than other commercial vaccines. This killed virus vaccine in oil emulsion provides more consistent high titers throughout the production period than the live virus vaccines.
  • The IB and ND viruses are contagious and can recycle within the flock. This can cause loss of egg production without symptoms. This vaccine protects the reproductive system against homologous strains and prevents such egg losses.
  • K Vac ND-IB is completely safe because it contains no living virus. It can safely be administered at any age.
  • It can not spread from vaccinated to susceptible flocks or be transmitted from dams to progeny. It provides high and persistent levels of antibody in the dams to provide parental immunity to the progeny.
  • Newcastle disease and Avian Infectious Bronchitis disease immunity are delivered to the farm with the chicks.

Dosage & Use

  • Birds should be "primed" with live virus Newcastle disease and bronchitis vaccine at least 4 weeks prior to the use of this vaccine.
  • Vaccinate with K Vac ND-IB at 16 to 20 weeks of age. If birds are held for a second year, revaccinate during molt.
  • Dosage is 1/2 ml (0.5 ml) per bird.
  • Vaccine should be brought to room temperature (+18°C to +20°C) before use.
  • Inject subcutaneously in the lower neck region using aseptic technique. Inject all birds in flock.


  1. Shake well before and during administration.
  2. Vaccinate only healthy birds.
  3. To avoid loss in efficacy and to prevent contamination, use entire contents of bottles when first opened.
  4. Do not vaccinate during 42 days before slaughter.
  5. All used bottles and unused content should be disposed safely.


Store between + 2°C ( 35°F) to 7°C (45°F). Do not freeze.


  • K Vac ND-IB is available in 500 ml polypropylene bottles. Each contains 1000 doses of vaccine.
  • 20 x 1000 dose.
