Administered orally to newborn calves within the first 12 hours of life, First Defense delivers targeted passive immunity directly to the GI tract, where it works locally to neutralize E. coli K99 and coronavirus before they can colonize and cause disease. Unlike colostrum, which provides systemic passive immunity, First Defense provides targeted local GI protection — making it a valuable complement to colostrum management in high-risk calving environments. Calf scours is the leading cause of death in beef and dairy calves, and E. coli K99 and coronavirus are two of the most significant infectious contributors. First Defense is the only USDA-licensed product of its kind proven to reduce the incidence of scours caused by these two pathogens. Sold in a 5-dose pack. Requires refrigeration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOral bolus delivering concentrated antibodies against E. coli K99 and bovine coronavirus\u003c\/li\u003e\n\u003cli\u003eProvides targeted local GI passive immunity — neutralizes pathogens before they colonize the gut\u003c\/li\u003e\n\u003cli\u003eAdminister within the first 12 hours of life for maximum effectiveness\u003c\/li\u003e\n\u003cli\u003eUSDA-licensed — the only product of its kind proven to reduce scours from E. coli K99 and coronavirus\u003c\/li\u003e\n\u003cli\u003eComplements colostrum management in high-risk calving environments\u003c\/li\u003e\n\u003cli\u003eEasy oral bolus administration — no injection required\u003c\/li\u003e\n\u003cli\u003e5-dose pack for calving season use\u003c\/li\u003e\n\u003cli\u003eRequires refrigeration — store between 35–45°F (2–7°C)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: ImmuCell \/ First Defense\u003c\/li\u003e\n\u003cli\u003eProduct: First Defense Scour Bolus\u003c\/li\u003e\n\u003cli\u003eCoverage: \u003cem\u003eE. coli\u003c\/em\u003e K99, Bovine Coronavirus\u003c\/li\u003e\n\u003cli\u003eAdministration: Oral bolus — within first 12 hours of life\u003c\/li\u003e\n\u003cli\u003ePack Size: 5 doses\u003c\/li\u003e\n\u003cli\u003eStorage: Refrigerate 35–45°F (2–7°C) — do not freeze\u003c\/li\u003e\n\u003cli\u003eSpecies: Beef and dairy calves\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eBest For\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eNewborn calf scours prevention in beef cow-calf and dairy operations\u003c\/li\u003e\n\u003cli\u003eHigh-risk calving environments where scours pressure from E. coli K99 and coronavirus is a concern\u003c\/li\u003e\n\u003cli\u003eOperations where colostrum quality or quantity is uncertain and additional GI protection is needed\u003c\/li\u003e\n\u003cli\u003eProducers looking for a USDA-licensed, proven scours prevention tool for newborn calves\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eAdminister within the first 12 hours of life per label directions.
