Gumboro disease (IBD) is very important disease in poultry industry. The very virulent strains of IBDV can result in mortality of up to 40%. Control is best achieved by improved biosecurity and vaccination. With special regard to animal welfare, the important advantage of IgY is that large amounts can easily be extracted from the yolk of immunized laying hens without any bleeding procedure. Under appropriate immunization schedules which strictly avoid intramuscular administration, IgY antibodies with very high titers and a strong binding capacity comparable to rabbit hyperimmune. Oral administration with yolk containing high titer of IgY has been proved to prevent many diseases occurrence. The aim of this study was the production of specific IgY against infectious bursal disease virus (IBDV) during the lag period of vaccine administration.
