  • Antibody-containing blend obtained from eggs
    Publication number: 20040120944
    Abstract: The invention relates to blending eggs from lots produced over the course of the egg laying cycle of immunized avians, to form an antibody-containing blend containing both early-stage antibodies and late-stage antibodies. The administration of an effective amount of such an antibody-containing blend to a subject increases the efficacy of the antibody blend its ability to bind antigen over that of a substance containing the same amount of antibody obtained from eggs containing either early-stage antibodies or late-stage antibodies only.
