The effects of hemoglobin (Hb) status and coping style of pigs on performance and humoral immune response were studied. Twenty-four, 4-wk-old crossbred barrows were assigned to groups of three pigs based on weight and litter origin. Groups were allotted according to a 2 x 2 factorial treatment arrangement: two blood Hb concentration classes (low vs high) and two immunization procedures (control vs immunized). Immunized pigs received an antigen cocktail containing keyhole limpet hemocyanin (KLH), ovalbumin (OA), and tetanus toxoid (TT) at weaning. Additionally, pigs were stratified according to behavioral coping style in response to exposure to a stressor. During 41 d after weaning (approximate time of immunization), blood Hb concentration, ADG, and ADFI were measured weekly and serum antibody titers to KLH, OA, and TT twice weekly. Average Hb concentration differed between low and high Hb pigs (P < .001; 10.0 vs 12.0 g/dL), but this difference declined with time after weaning. Neither immunization procedure nor coping style affected Hb concentrations. In addition, ADG and ADFI were unaffected by any of the treatments. However, ADG was slightly greater in high Hb status pigs (586 vs 633 g/d) and was paralleled by a slightly greater ADFI in high Hb status pigs (812 vs 899 g/d). Antibody responses were negatively or not related to Hb status at weaning. Antibody responses (depending on isotype and antigen) were or tended to be lower in pigs with high blood Hb concentrations. Behavioral coping style strongly affected humoral immune responsiveness; enhanced or accelerated antibody responses were found in pigs that had a passive coping style.
