Stochastic models to simulate paratuberculosis in dairy herds.
Stochastic simulation models are widely accepted as a means of assessing the impact of changes in daily management and the control of different diseases, such as paratuberculosis, in dairy herds. This paper summarises and discusses the assumptions of four stochastic simulation models and their use in the design of certification, surveillance, and control strategies for paratuberculosis in cattl...
متن کاملRisk management of paratuberculosis in dairy herds
Risk management of paratuberculosis (Johne's disease) in a dairy herd requires an assessment of the likelihood of paratuberculosis occurring in the herd, the economic impact of paratuberculosis on the herd and an evaluation of measures that can be taken to reduce this likelihood and impact.The likelihood of paratuberculosis occurring in the herd is related to the regional herd-level prevalence ...
متن کاملEconomic Consequences of Paratuberculosis Control in Dairy Cattle Herds
The PTB-Simherd is a dynamic, stochastic, and mechanistic Monte-Carlo model simulating adairy herd including young stock. Paratuberculosis and relevant control strategies against thisdisease was built into an existing simulation model. The model is able to simulate bothepidemiological, technical and economic consequences of paratuberculosis and controlstrategies against it in th...
متن کاملDecision analysis model for paratuberculosis control in commercial dairy herds.
A previous economic test-and-cull decision analysis model has been strengthened and updated with current epidemiologic information. Created using Excel and PrecisionTree software, the model incorporates costs and benefits of herd management changes, diagnostic testing, and different management actions based on test results to control paratuberculosis in commercial dairy herds. This novel "JD-Tr...
متن کاملPrevalence of paratuberculosis in organized and unorganized dairy cattle herds in West Bengal, India
AIM The aim of this study was to determine the prevalence pattern of Mycobacterium avium subsp. paratuberculosis, the causative agent of paratuberculosis or Johne's disease, in unorganized as well as organized cattle herds in West Bengal. MATERIALS AND METHODS Four organized cattle farms with identical management practice in Nadia (n=3) and South 24 Parganas (n=1) districts and three unorgani...
