Erratum: Effect of serum total protein concentration on early-life health and growth of dairy calves

In the article “Effect of serum total protein concentration on early-life health and growth of dairy calves” (J Am Vet Med Assoc 2020;257:80–86), the Results section of the abstract should read as follows: “STP concentration was associated with the incidences of death, diarrhea, pneumonia, and whether a calf received IV fluid therapy. In general, the incidence of adverse health events decreased as STP concentration increased to 6.0 g/dL and plateaued at STP concentrations between 6.0 and 8.5 g/dL. For Holsteins, the ADG increased as STP concentration increased, although the death rate increased at STP concentrations > 8.5 g/dL.” The Conclusions and Clinical Relevance section of the abstract should read as follows: “Results suggested that, for neonatal dairy calves, an STP concentration between 6.0 and 8.5 g/dL was optimal for health and growth. Calves with an STP concentration < 5.0 g/dL should be considered at high risk for adverse health events, and Holstein calves with an STP concentration > 8.5 g/dL should be considered at risk for death.” Finally, the weights and ADG information provided in Table 4 were reported in pounds instead of kilograms. Table 4 should read as follows:
