First Defense protects calves from scours by giving them antibodies directly. Calves receive an instant dose of immunity from the most common scours pathogens. There’s no reliance on dam- or calf-level vaccines to stimulate an antibody response. Your calves can jump straight to guaranteed levels of immunity from E. coli, coronavirus and rotavirus.
