QIE Wen-li(Office of Teaching Affaires,Binzhou Vocation College,Binzhou,Shandong 256603)  
High immunized vitelline antibodies were developed by the healthy high-yield layers immunized with duck viral hepatitis(DVH) attenuated live vaccine and DVH oil-emulsion inactivated vaccine in order to study the cure effect of high immunized vitelline antibodies against young duck DVH.Results showed that the cure effect of high immunized vitelline antibodies against young duck DVH depended upon neutralization titer,cured time and immunity approach.The immunity of young duck could get optimum effect when the vitelline antibodies should have neutralization titer over 28.5 and were injected into the muscle of young ducks infected by DVH within 24 h.
