ABSTRACT
Through determining the serum and egg yolk antibody titers in immunized laying hens to Pasteurella multocida regularly, the growth-decline trend of the egg yolk antibody levels was found to be similar to that of the serum antibody levels (r = 0.94), but the growth and decline of the egg yolk antibody seemed to be delayed 3-6 days compared with that of the serum antibody, and the egg yolk antibody titers were generally lower than those of the serum antibody (P < 0.01). Serum and egg yolk antibody levels declined 3 and 6 days, respectively, after booster immunizations. The higher the antibody levels were before booster immunization, the more they declined.
