Financial impact of endemic and epidemic pathogens in growing pigs

摘要

Despite the efforts invested on the control of endemic diseases in the US swine industry, quantification of their financial impact throughout the production chain is often hampered by the lack of data or data analysis capabilities.1 There are studiesthat have evaluated the effect of disease in sow farms, however there are important knowledge gaps regarding the full impact of endemic and epidemic diseases in growing pigs. We hypothesized that the analysis of production records routinely collected ingrowing pigs together with laboratory and clinical information on the presence of selected endemic pathogens in sow and growing pig farms can help to fully evaluate their production impact, thus helping to inform the decision-process with regards to theimplementation ofcontrol/eradication strategies. Three diseases [porcine epidemic diarrhea (PED), influenza A (IA) and porcine reproductive and respiratory syndrome (PRRS)] were selected based on their economic importance, widespread distribution, and different epidemic/endemic nature in the US swine industry.
