Development of a field test to evaluate colostrum quality (IgG) in cattle

Abstract

Failure of transfer of immunity from dam’s colostrum generates a negative effect on calves’ health leading to increased morbidity and mortality (De Nise et al., 1989; Wittum and Perino, 1995). Immunoglobulins (IgG) content of colostrum is highly variable and cannot be predicted. Distinguishing good from poor quality colostrum allows to adapt the volume administered or to initiate ancillary procedures for a sufficient transfer of IgG. The aim of the study was to evaluate the performances of a field test for colostrum quality determination
