Abstract

Serum antibody titers for avian encephalomyelitis virus of vaccinated breeding hens were correlated with the resistance of the hens' progeny embryos to viral challenge. All of the embryos from hens that had enzyme-linked immunosorbent assay titers greater than 400 were resistant to challenge, and two-thirds of the embryos from hens that had titers greater than 300 were resistant. About one-half of the embryos from hens that had titers from 100 to 300 were immune to challenge. /// Los títulos de anticuerpos séricos contra el virus de la encefalomielitis aviar de gallinas reproductoras vacunadas se correlacionaron con la resistencia al desafío de los embriones progenie. Todos los embriones provenientes de reproductoras con títulos ELISA de màs de 400, dos tercios de los embriones de reproductoras con títulos de más de 300 y la mitad de los embriones de reproductoras con títulos de 100 a 300 fueron resistentes al desafío.
