Abstract

Calves with failed transfer of passive immunity (FTPI) possess increased risk of preweaning disease. Common tests for FTPI such as radial immunodiffusion (RID) and optical refractom­etry (OR) have inherent imprecision. The objective of this study was to estimate test sensitivity and specificity for various IgG concentrations and serum total protein values (STP) to classify neonatal beef calves with FTPI.
