First Defense Dual-Force 12 Dose

Dual-Force gel has been proven effective for passive immunity against K99+ E.coli and Bovine Coronavirus when administered orally within 12 hours of birth. Feed entire tube contents to calf and do not split dose between multiple calves. Blue, non-digestible dye serves as a tracker through the system to ensure calf received treatment and therefore, first fecal stool after administration will be blue-green in colour. Store refrigerated (2-8 degrees C).
