1. A dry whey protein powder fortified with polyclonal antibodies against preselected infectious intestinal disease antigens made according to a method comprising the steps of:

  • a. immunizing a pregnant ungulate by administration to the ungulate of the preselected infectious intestinal disease antigens in a non-pathogenic condition;

    b. collecting and maintaining the milk from the ungulate after parturition, the milk containing a higher than normal concentration of antibodies against the preselected infectious intestinal disease antigens because of the immunization step;

    c. producing unfractionated whey fortified with naturally occurring polyclonal antibodies against the preselected infectious intestinal disease antigens from the milk by removing milk casein; and

    d. concentrating and drying the unfractionated whey to produce a whey protein powder fortified with naturally occurring polyclonal antibodies against the preselected infectious intestinal disease antigens.
