Contains a special formulation of lactic acid-producing bacteria, dried milk, protein, lactase enzymes and dried egg solids to aid in fighting disease, minimize intestinal infections and enhance appetite and digestion. Also helps increase energy levels. Calves become more active and vigorous resulting in increased nursing action and higher colostrum intake. Use in conjunction with high levels of antibiotics in feedlot or dairy cattle to establish naturally occurring beneficial bacteria in the gut. Non-medicated formula. No withdrawal. Contains 10 million CFU total lactic acid bacteria.
