摘　　要： 　用猪源大肠杆菌单价(K88)与三价(K88、K99、987P)灭活疫苗分别免疫产蛋母鸡,定期检测母鸡血清和卵黄的抗体效价。结果表明,两种疫苗免疫母鸡的卵黄抗体和血清抗体的消长规律基本一致,但前者比后者上升和下降期有所滞后;血清抗体水平比卵黄抗体水平平均约高21 8以上,两者间的差异极显著(P<0 01)。 Through determining the serum  antibody and yolk  antibody titers regularly in laying hens vaccinated with swine Ecoli (K88) or trivalent (K88, K99, 987P) inactivated vaccines, it was found that the growth  decline trends of yolk  antibody and serum  antibodies were generally similar, but the yolk  antibody titers inclined to delay at the beginning of ascending or declining period, and that the average of yolk  antibody titers decreased by 218 as compared with serum antibody titers ( P<001)
