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.
