Newcastle disease is one of the most significant poultry diseases worldwide because of its wide distribution, high mortality rates and meat export restrictions.

With a huge distribution, it is known in South Africa as a disease controlled by vaccination programmes in layers, broiler breeders and broilers.

 

As shown in this trial, animals vaccinated against Newcastle disease (ND) and challenged with a common Infectious Bronchitis (IB) strain located in a country, in this case South Africa, do not show differences with other birds not vaccinated and challenged with the same kind of IB isolate or with birds not vaccinated against ND and not challenged with an IB isolate.
