ABSTRACT:
This invention provides a method of reducing the output of Eimeria oocysts from a newborn chick which comprises administering to a laying hen at a suitable time prior to the hen laying a fertilized egg an amount of native or recombinant antigenic protein present in gametocytes of the Eimeria spp. effective to induce in the hen an immune response conferring protection via maternal immunity against infection or transmission by the Eimeria spp. in the offspring chick.
