First Defense Bolus

An immediate guaranteed dose of immunity against E. coli and coronavirus infections, in a bolus form.

• Instantly deliver the passive antibodies newborn calves need to prevent scours.
• Jump straight to antibody protection while removing reliance on the common variable vaccine response of dam- and calf-level vaccines.

One dose, a single bolus or gel tube, administered at birth gives each calf a guaranteed level of protection from E. coli and coronavirus infections.
