Serum-haptoglobin concentration in Danish slaughter pigs of different health status.
A cross-sectional study was conducted with 617 finishing pigs aged 10-25 weeks in 11 commercial herds of different health statuses as defined by the Danish monitoring program for specific-pathogen-free (SPF) herds. A standard clinical examination was performed and a blood sample was obtained from each pig for determination of haptoglobin concentration in serum. Pigs aged 10-14, 15-19 and 20-25 weeks in conventional herds had higher haptoglobin concentrations than high-health SPF (SPF-x) pigs of the same age. There was no significant difference between SPF-x pigs of different ages. Conventional pigs aged 15-19 and 20-25 weeks had higher haptoglobin concentrations than conventional pigs aged 10-14 weeks. Herd influenced the haptoglobin concentration. Lame pigs and pigs with tail or ear bite had elevated haptoglobin concentrations. No significant effect of respiratory symptoms or umbilical hernia was found.
