First Defense Technology® Calf Scours Prevention

A 90-dose bulk powder with a guaranteed dose of immunity against E. coli and coronavirus.

First Defense Technology uses the same hyper-immunized colostrum antibodies as our USDA-approved First Defense bolus. It contains the same active ingredient at the same dose rate as our bolus. Its antibodies bind to, and neutralize, E. coli and coronavirus disease antigens, delivering instant immunity without putting vaccination stress on the newborn.

Watch our sales and marketing team answer the seven questions we get asked the most.

“Prior to adding First Defense to our regimen, our calves would always run into problems with salmonella after having scours seven to 10 days after birth. We have been using First Defense at Cal Poly State University’s dairy unit and have seen calves getting through the first two weeks of life stage really successfully. We would recommend First Defense to anyone. This product is simple to administer and produces results.”
