Antibody titers to keyhole limpet hemocyanin in healthy and footrot-affected sheep treated with selenium or saline. Footrot-affected (FR) sheep, regardless of Se treatment, had A) lower keyhole limpet hemocyanin (KLH) antibody titers 2 and 4 weeks after the second KLH immunization compared with healthy sheep (overall: P = 0.02). B) After stratifying FR-affected sheep by whole-blood Se (WB-Se) status at the time of the immune assay (WB-Se cut-off: 250 ng/mL), sheep with WB-Se concentrations below 250 ng/mL (FR-Low Se) had lower KLH antibody titers compared with healthy sheep (overall: P = 0.02), whereas sheep with Se concentrations above 250 ng/mL (FR-High Se) had intermediate values (overall: P = 0.09 versus healthy sheep; overall: P = 0.48 versus FR-Low Se sheep).
