Tri-Shield Gel Tube
Tri-Shield First Defense® Calf Scours Prevention
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.

Proven to provide passive immunity against the three most common scours-causing pathogens and reduce rotavirus shedding.
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.
Reduces Rotavirus Shedding
A recent study by Skidmore et al* demonstrated that Tri-Shield significantly reduced rotavirus shedding in calves during the height of the disease, including those that achieved successful passive transfer from a quality colostrum feeding. As a result, you can limit the rotavirus pathogen in the calf environment, reduce the level of disease challenges herd mates are exposed to, and reduce the frequency and severity of scours outbreaks.
“You can just compare calves that you have on First Defense compared to calves that aren’t. There’s definitely a big difference. Maybe not day one, but as they’re in their first three weeks when they’re in the calf hutches and they’re on milk. Once they start grain, we noticed a big difference on their milk and grain intakes, as well as just being healthier all around.”
