What is Our Philosophy?

At ImmuCell we have a desire to make life easier and business more profitable for dairy and beef producers.  We hate fluff so are committed to meeting USDA, CFIA, FDA, and OMRI standards for efficacy.  We also hate inflating prices to cover bureaucratic overhead which is why we run lean, logical, committed to our customers and results.

Why Choose ImmuCell?

ImmuCell holds a unique position, they are the only animal health company with the ability to concentrate, purify, and quantify specific colostrum antibodies (E. coli, coronavirus, and rotavirus) on a commercial scale. This has resulted in products to treat one of the two most frustrating problems within commercial beef and dairy operations – calf scours.
