Tri-Shield First Defense Paste

Built for operations that want the widest possible protection. Tri-Shield is made from hyperimmune bovine colostrum, providing immediate antibodies against the three most common scours pathogens: E. coli, coronavirus, and rotavirus. One oral gel tube given at birth binds and neutralizes pathogens in the gut, delivering instant immunity during the calf’s most vulnerable first days. Tri-Shield also includes a non-digestible blue dye protocol marker and is CFIA-approved.
