Protecting animal health and profitability via air filtration solutions, a front line defense against PRRSV, PEDV, and influenza

摘要

While virus outbreaks are not the only risk sow farm facility managers have to consider when allocating capital for operations, it is one that should be given serious consideration, based on its potential to significandy impact production and costs. Research findings on the impact of these diseases clarify the risk of substantial losses due to an outbteak. A 2013 study published in the Journal ofSwine Health and Production estimated that the annual cost of productivity losses due to PRRSV in US national breeding and growing pig herds to be $664 million, up from $560 million in 2005. This equates to a loss of $ 1.8 million per day by the US pork industry (Figure 1). An additional $477.8 million is estimated to be lost each year on outbreak-related costs, including animal care and bi-osecurity. As an example, a feeder-pig operation with an endemic PRRSV infection in the nursery reported a 70% loss in profits due to a reduction of over $5.00 per pig attributed to the nursery stage alone, based on decreased growth rates, increased feed conversion, and increased mortality.1 The likelihood of sustaining losses is increased if the operation is located within a five mile radius of othersow farms. The PRRSV virus can travel airborne for five miles or more, and its ability to constantly change creates the potential fot genetic evolution of the strain.
