Comparison of two attenuated infectious bursal disease vaccine strains focused on safety and antibody response in commercial broilers.

ABSTRACT:

Background and aim

Infectious bursal disease (IBD) or Gumboro disease is one of the most detrimental diseases in the poultry industry worldwide. Previous scientific studies have shown that live IBD vaccination might induce transient immunosuppression, leading to suboptimal vaccine responses, and therefore lack of protection against other infectious diseases; therefore, selecting an IBD vaccine in commercial farms is a concern. This study aims to compare two commercially attenuated IBD vaccines (intermediate and intermediate-plus strains) in terms of safety and antibody response to IBD and Newcastle disease viruses (NDV) in commercial broilers.

Materials and methods

Overall, 216 Cobb broiler chickens were divided into three groups based on the IBD vaccine strain administered:
