Abstract
    The present study was designed to follow up the immune status of lambs born from ewes vaccinated with Alhydragel Bivalent Foot and Mouth Disease FMD vaccine 3 months before parturition. Estimation of antibody titer before parturition; at parturition and in colostrums of dams in addition to the acquired maternal antibodies in new born lambs was performed weekly till such titers declined to the nonprotective level using serum neutralization test (SNT) and enzyme linked immunosorbent assay (ELISA). The study suggested that it is necessary to vaccinate newly born lambs to ewes vaccinated with alhydragel bivalent Foot and Mouth Disease FMD vaccine on the second month of age to protect them against infection with FMDV strains "O" and " A".
