| Abstract: | The day old broiler chickens possessing IBD precipitating maternal antibody when exposed either to IBD contaminated environment or challenged intrabursally with virulent virus at weekly intervals indicated 100% susceptibility around 4–5 weeks of age. However, chickens lacking maternal antibody upon intrabursal challenge were found susceptible by 2 weeks of age. |
