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

First Defense is the only USDA- and CFIA-approved colostrum-derived product that protects newborn dairy and beef calves against K99+ E. coli and bovine coronavirus. With a single dose, it provides immediate immunity, is OMRI-listed for organic use, and contains antibodies from hyperimmune bovine colostrum for protection against bacterial and viral scours.

It is easy to administer orally with a bolus gun or mixed into colostrum, involves no vaccination stress, and requires no withholding time. Ingredients meet NOP/USDA standards, offering natural protection to reduce death loss and improve calf health.

Directions: Administer 1 capsule to neonatal calves within 12 hours of birth. The capsule dissolves in the calf's stomach, delivering antibodies that block E. coli adherence and prevent coronavirus infection, reducing scours-related morbidity and mortality. For best results, use alongside good colostrum feeding and calf nutrition programs.
