Poly Serum contains protective antibodies required to prevent scours and pneumonia in baby calves and other cattle. Poly Serum is a highly effective colostrum supplement in situations where colostrum quality and quantity are questionable. It is especially useful for purchased baby calves where colostrum intake is unknown.

Poly Serum contains antibodies from five organisms commonly associated with diarrhea and respiratory problems in baby calves and other cattle. It fortifies treatment programs when used therapeutically with antibiotics or other drugs when treating diarrhea or pneumonia. These five organisms are: Pasteurella multocida, Mannheimia (Pasteurella) haemolytica, Actinomyces pyogenes, E. coli, and Salmonella typhimurium.
