Since the initial occurrence of Infectious Bursal Disease (IBD) in the US, the disease has spread globally. By 1976, mortality caused by IBD was under control following extensive vaccination and increased biosecurity. The US poultry industry currently follows several approaches to combat the impact of the disease on their flocks.
The US poultry industry is to a large extent fully integrated, in which many efforts are made to build a strong immunity in the breeder stock to prevent disease in both the breeder production cycle and in the broiler offspring. As IBD is a resident disease, the virus can easily survive in litter and other organic materials. A common practice is to immunise breeders by including one or two inactivated IBD strains in the vaccines.
Generally, these vaccines contain both classic and variant IBD strains and are available in combination with Newcastle Disease (ND) and IB strains.
