    K99+ E. coli

    DUAL-FORCE has been shown to be effective for passive immunity against K99+ E. coli and bovine coronavirus when administered within 12 hours of birth.

    Specifically, DUAL-FORCE aids in the reduction of mortality and morbidity from both bacterial and viral scours caused by K99+ E. coli and bovine coronavirus.

    DIRECTIONS: Do not delay colostrum. For best results, DUAL-FORCE gel should be administered to calves orally, within 12 hours after birth. Remove the tube cap, placing the tip at the back of the throat, toward the cheek pocket. Initiate the plunger and squeeze the entire tube contents into the calf’s mouth, ensuring the calf swallows all of the gel.

    PRECAUTIONS: Store refrigerated (35-46°F, 2-8°C). Do not split dose between multiple calves. Use entire contents when first opened. Blue dye is non-digestible serving as a tracker through the system to ensure calf received treatment. First fecal stool after administration will be blue-green in color. For use in animals only. Do not mix with other products, except as specified on the label. Preservative: Thimerosal
