First Defense®

Currently the only USDA-approved colostrum derived product to defend against both K99+ E. coli and coronavirus, First Defense® can be delivered to the calf at birth, the same time as colostrum. First Defense® delivers Immediate Immunity when calves need it most. Maximal protection is achieved when administered in the first 12 hours after birth and used in conjunction with good colostrum feeding and calf nutrition programs. Available in bolus, gel and powder form.
