Product is currently on manufacture backorder. Orders placed for this product will be added to the fulfillment queue when stock becomes available.

Provides immediate and lasting immunity for newborn beef and dairy calves. It is a single-dose gel tube and the only veterinary biologic with a guaranteed dose of immunity against E.coli, coronavirus and rotavirus.  

A single-dose gel tube of Tri-Shield administered at birth, along with maternal colostrum, has been proven effective in third-party research to provide passive immunity against K99+ E. coli, bovine coronavirus, and rotavirus infections.

Approved by the USDA Veterinary Center for Biologics, Tri-Shield immediately delivers a guaranteed dose of passive antibodies to newborn calves. Unlike a dam- or calf-level vaccine that works to create an antibody response, Tri-Shield antibody therapy provides direct immunity.
