- First economic models showing impact of post-weaning multi-systemic wasting syndrome (PMWS) on British Pig Industry published
- Between 8 to 84 per pig lost, depending on severity of PMWS
- Farm-level intervention could save farmers up to 11,500 per year
Stark new figures show that a common pig virus, present on 99 per cent of pig farms has major economic implications for individual farmers and the pig industry as a whole, costing British farmers as much as 84 per pig (if the pig dies from the syndrome), and during epidemic periods, such as 2008, costing the pig industry 88M per year.
PMWS, a serious syndrome which results in emaciation and death in up to 30 per cent of cases. As part of a BBSRC-led initiative into combating endemic diseases of farmed animals, researchers from the Royal Veterinary College (RVC) have spent the past five years working to understand the factors that lead to farms developing high rates of PMWS and creating models to work out the cost of the disease as well as the potential savings for farmers by tackling the disease in different ways.
Professor Dirk Werling, from RVC, who led the project, explains: "We've known for many years that this is a serious disease in pigs. It is now endemic globally and will haunt the pig industry for years to come; therefore it is crucial that we understand the biological basis of the virus as well as the cost implications. Knowing the financial impact of the illness can help farmers decide how best to improve the welfare and profitability of their herds. These figures are shocking, but are an important step in enabling farmers and the industry as a whole to look at feasible and sustainable intervention strategies."
Dr Pablo Alarcon, Professor Jonathan Rushton and Dr Barbara Wieland, all from RVC, produced a series of mathematical models, factoring in different scenarios such as the size of the pig herds, the proportion affected by PMWS and the severity of the infection. In the most severe cases where the infected pig dies from PMWS, this costs the farmer an estimated 84, with the least severe case - where a pig is carrying the virus but displays no clinical symptoms cost 8.
Models were then created to look at the cost implications of employing different control measures at individual farm level, ranging from vaccination of piglets through to total repopulation of a farm's pig stocks. Their model suggests that on farms with moderate to high rates of PMWS the most cost effective strategy is to vaccinate all piglets and increase biosecurity measures, such as a two day quarantine period for people who had come into contact with other pig herds and treating pigs with PMWS in isolation. Savings from this dual approach were worked out to be between 2,947 to 11,500 per year.
BBSRC Chief Executive Professor Douglas Kell said: "Food security and the sustainability of UK farming are seriously undermined by endemic diseases of farmed animals. This important new research shows the significant economic impact that diseases such as PMWS can cause, and highlights the vital role researchers play in working with farmers and industry to improve food security and animal welfare"

Notes
The two papers were published in March in the journal of Preventative Veterinary Medicine:
Cost of post-weaning multi-systemic wasting syndrome and porcine circovirus type-2 subclinical infection in England - An economic disease model.
Alarcon P, Rushton J, Wieland B.
Prev Vet Med. 2013 Mar 12. doi:pii: S0167-5877(13)00041-X. 10.1016/j.prevetmed.2013.02.010
Economic efficiency analysis of different strategies to control post-weaning multi-systemic wasting syndrome and porcine circovirus type 2 subclinical infection in 3-weekly batch system farms.
Alarcon P, Rushton J, Nathues H, Wieland B.
Prev Vet Med. 2013 Jan 31. doi:pii: S0167-5877(12)00412-6. 10.1016/j.prevetmed.2012.12.006.
Porcine circovirus type 2 subclinical infection (PCV2) is a very common virus found on virtually all pig farms, and is responsible for PMWS. The disease was first seen in the UK in 1999. The disease strikes young pigs from about six-weeks after they have been removed from their mothers; they then lose weight, have difficulty breathing and can suffer from fever and diarrhoea as they slowly become emaciated.
About BBSRC
BBSRC invests in world-class bioscience research and training on behalf of the UK public. Our aim is to further scientific knowledge, to promote economic growth, wealth and job creation and to improve quality of life in the UK and beyond.
Funded by Government, and with an annual budget of around 500M (2012-2013), we support research and training in universities and strategically funded institutes. BBSRC research and the people we fund are helping society to meet major challenges, including food security, green energy and healthier, longer lives. Our investments underpin important UK economic sectors, such as farming, food, industrial biotechnology and pharmaceuticals.
