First Defense Technology® Bulk Powder
ImmuCell’s Functional Feed line is built on hyperimmunization technology. Colostrum is collected from cows hyperimmunized against either E. coli and coronavirus or rotavirus, resulting in concentrated colostrum powders containing powerful bioactive proteins.
First Defense Technology® Hyperimmune Colostrum – Concentrated Bovine Bioactive Proteins and Colostral Fat
The powders are designed for easy administration to large groups of calves through addition to the milk, making them especially practical for larger calf operations.
Products can be fed individually based on the specific needs of the farm or blended together to provide the broadest spectrum of coverage.
Available in 25-pound bags or 5-pound pails
Administration options
For progressive operations using a phase-feeding approach, 30 grams of E+C can be followed by 30 grams of R. Alternatively, the two products can be combined in a single 60-gram feeding or titrated over multiple days.
This flexibility allows you to tailor the feeding program to deliver the right targeted protection at the right time.
Research presented at the 2026 International Colostrum Symposium:
30 grams of E+C administered to calves upon arrival at a calf ranch resulted in more uniform health outcomes in calves with inadequate passive transfer while providing an additive effect for calves with adequate passive transfer including 50% lower pre-weaning removal rates and 25% fewer pneumonia treatments.
