Abstract

Effective control of infectious bursal disease (IBD) is largely dependent on attainment of high level of maternal antibody in chicks. However, outbreaks still occur, and variable antibody titres and duration of immunity have been reported in chicks. Rates of maternal antibody transfer from parent stocks to progeny were determined and decay rates in chicks were evaluated. Four chicken breeder flocks (A, B, C and D) were bled and IBD antibody titers were determined using ELISA. Antibody titres in yolk of eggs laid on the same day of bleeding and chicks hatched from the same batches of eggs at days one and seven, were also determined. Mean titres were compared for significant differences using ANOVA and LSD test of multiple comparisons at p < 0.05. Rates of maternal antibody transfer from parent stocks A and B (administered one dose of inactivated vaccine) to their respective progenies were 77.4% and 89.9%, while it was 51.1% and 50.4% in C and D (administered two doses), respectively. However, the rates of decay of maternal antibody from one-day-old to seven-day-old chicks were 58.9%, 48.7%, 24.4% and 54.9% in chicks A, B, C and D, respectively. A negative correlation (r = -0.9878) was observed between antibody titres in parent stocks, yolk as well as chicks’ sera and maternal antibody decay rates. Multiple administration of inactivated IBD vaccine by point-of-lay caused low rate of maternal antibody transfer to progeny and low maternal antibody titer at 1-day-old caused higher rate of decay in chicks.
