Presence and levels of maternal antibody (MA) in broiler chicks derived from hens vaccinated with a live infectious bursal disease (IBD) vaccine were investigated by a quantitative agar-gel precipitin test. At day old 100% of the chicks tested had MA; by 17 days of age it was present in only 10%. The mean MA level at day old was 337.5 UK units/ml but decreased to 6.3 UK units/ml at 17 days of age. Randomly selected chicks from the pool studied were challenged at weekly intervals from day old for 29 days with an IBD virus obtained from a natural outbreak. Subclinical and clinical disease were observed in chicks challenged at eight and 29 days of age respectively.
