Towards an eradication strategy for Mycoplasma hyopneumoniae from the UK pig herd

Home \ Research & Innovation \ Research \ Health \ Towards an eradication strategy for Mycoplasma hyopneumoniae from the UK pig herd

Research partner: The Royal Veterinary College, Veterinary Laboratories Agency, BBSRC

Sponsor: AHDB Pork-funded studentship (Veronica Brewster)

Duration: 2009 – 2014 

Aims and objectives

  • To develop and validate immunohistochemistry (IHC) as a diagnostic tool for Mycoplasma hyopneumoniae
  • To determine the impact of enzootic pneumonia-like (EP-like) lesions on post trimming carcase weight
  • To undertake a feasibility assessment on the eradication of M. hyopneumoniae. 

Findings to date

  • A significant association was identified between increasing severity of EP-like lesions and a decrease in post-trimming slaughter weight
  • On an individual level, each 5-point increase in EP-like lesions equates to around -53p/pig
  • On a batch level, each increase of 1 point score equates to -50p/pig
  • An increase in EP-like lesion severity was significantly associated with an increase in slaughter age.
