Development of an Acute Phase Protein Index as an objective indicator of sub-clinical disease status in pigs

Home \ Research & Innovation \ Research \ Health \ Development of an Acute Phase Protein Index as an objective indicator of sub-clinical disease status in pigs

Research partners: SAC, University of Glasgow, ABN Ltd, Pfizer Animal Health Ltd, JSR Genetics Ltd. QMS and AHDB Pork

Sponsors: The above mentioned industrial partners with match funding from Scottish Government (RERAD) under the Sustainable Livestock Production LINK programme

Duration: 2008 – 2009 

Aims and objectives

To assess whether serum acute phase proteins (APP) can be used as objective markers to:

  • Determine the contribution of sub-clinical disease to sub-optimal pig performance
  • Detect the presence of sub-clinical disease in pigs 

Findings to date

This feasibility study has shown that sub-clinical infection in young pigs evokes APP responses, and that an APP Index has the potential to assess, objectively, the presence and extent of sub-clinical disease in pigs. Further studies are required to verify observed findings under practical conditions and to address further the relationship between APP responses and feed intake per se.
