The method of producing a microbial adherence inhibitor for administration to food animals to control the incidents of acidosis in food animals by preventing the adherence of colony-forming lactic acid producing bacteria in the rumen or intestinal tracts of the food animals. The method includes inoculating female birds in or about their egg laying age with a lactic acid producing bacteria that colonizes in the intestinal tract of the food animal to be treated. Allowing a period of time sufficient to permit the production in the birds of antibody to the lactic acid producing bacteria and harvesting the eggs laid by such birds. The antibody-containing contents of the eggs are then separated by the shells.
