Method of producing antibody-fortified dry whey

A method of preventing an intestinal disease in a human or animal comprising prophylactically administering to the human or animal an effective oral dose of a dry whey powder fortified with polyclonal antibodies against antigens associated with the intestinal disease made according to a method comprising the steps of:

• a. immunizing a pregnant ungulate by administration to the ungulate the antigens associated with the intestinal disease 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 polyclonal antibodies against antigens associated with the intestinal disease because of the immunization step;
• c. producing unfractionated whey fortified with naturally occurring polyclonal antibodies against the 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 intestinal disease antigens.
