The immune responsiveness to infectious bursal disease virus (IBDV) in four native and crossbred chicken lines was compared. ELISA IBDV antibody titers in hen serum samples, yolk from matched eggs and sera from matched 1-day-old chicks from each chicken line with an identical vaccination program were measured, and plotted. There was considerable variation between lines in the measured IBDV specific antibodies, in vaccinated parent hens and in the amounts of inherited maternally derived antibodies in both yolk and progeny chicks. Differences in ratios of the inherited antibody level from hen to 1-day-old chicks were also found among different chicken lines. Breed differences in regressions of IBDV antibody levels in yolk to that of hen or progeny chicks' sera were also found, so prediction of serum titer of hen and/or progeny chicks from yolk are varied among chicken lines.
比较了四个本地和杂交鸡品系对传染性法氏囊病病毒（IBDV）的免疫反应性。对每个鸡品系具有相同疫苗接种程序的母鸡血清样本、匹配鸡蛋的蛋黄以及匹配的1日龄雏鸡的血清中的IBDV抗体滴度进行了测量，并绘制了图表。在接种疫苗的亲代母鸡中，所测量的IBDV特异性抗体以及蛋黄和子代雏鸡中母源抗体的含量在品系之间存在相当大的差异。不同鸡品系之间还发现了母鸡与1日龄雏鸡遗传抗体水平比率的差异。还发现了蛋黄中IBDV抗体水平与母鸡或子代雏鸡血清抗体水平回归的品种差异，因此不同鸡品系中根据蛋黄预测母鸡和/或子代雏鸡血清滴度的情况各不相同。
