Efficacy of feeding First Day Formula® CR versus maternal colostrum on calf serum immunological parameters

Abstract

Commercially available colostrum replacers (CR) are commonly used for convenience when maternal colostrum (MC) is unavailable, of questionable quality or in disease control programs. The objective was to determine the efficacy of a colostrum-derived CR, First Day Formula® CR (Accelerated Genetics, Baraboo, WI), vs raw MC on immunological parameters.
