THE DEVELOPMENT OF A FARM LEVEL DECISION SUPPORT MODEL CAPABLE OF DEMONSTRATING THE COSTS AND BENEFITS OF CONTROLLING MYCOPLASMA HYPNEUMONIAE IN FINISHING PIGS
I. McClement and R. Bennett

Abstract
Mycoplasma hyopneumoniae is a significant economic problem for the UK pig industry and its costs are difficult to estimate. This research was to develop an interactive farm-level Decision Support System simulation model to demonstrate the estimated economic impact of Mycoplasma hyopneumoniae and the costs and benefits associated with farm disease control measures. To quantify its impacts, the model uses the farm's own abattoir report data based on carcass examinations at slaughter provided by membership of the British Pig Executive (BPEX) Pig Health Scheme. This enables loss related to decrease in live-weight gain and depression in feed conversion efficiency to be calculated.
