First Defense Technology 90-Dose Bulk Powder, Nutritional Health Supplement for Newborn Calves, 375gm

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.
