Preventing Costly PRRS Outbreaks


The pathogen Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) was first recognized in the United States in the late 1980s. Despite more than 25 years of intensive research and efforts to combat the virus, it remains a significant threat to swine farms in both the U.S. and abroad. While productivity losses resulting from the impact of the disease on growing herds have been reduced over the past decade, this progress is offset by significantly increased losses in breeding herds.

While a PRRSV outbreak is not the only risk a sow farm has to consider when allocating capital for operations, it is one that should be given serious consideration, based on its potential to significantly impact production and costs. The likelihood of sustaining such losses due to an outbreak of aerosolized PRRSV is increased if your operation is located within a five-mile radius of other sow farms. The virulent virus can travel airborne for five miles or more, and its incredibly high mutation rate makes the development of a consistently effective vaccination program difficult.

Trials conducted by the University of Minnesota Swine Disease Eradication Center found that the risk of the indirect spread of PRRSV can be reduced with a comprehensive biosecurity program that includes air filtration. Unfortunately, most ventilation systems in swine facilities are typically designed to supply fresh air and control the inside temperature, not to provide air filtration. However, an effective air filtration system traps airborne viruses such as PRRSV and other common threats, including PEDV, influenza viruses, and mycoplasma hyopneumoniae, preventing them from entering a facility and spreading throughout.

At AAF, we understand the threat that swine farming operations face from the virulent and costly PRRS virus, as well as other pathogens with the potential to have a significant impact on your herd, production levels, and operating costs. Our goal is to provide you with comprehensive information for assessing your risk, and filtration investment strategies to reduce your risk and the projected return on your investment. AAF offers air filtration solutions and climate control options to meet the unique needs of your farming operation, protecting both animal health and profitability.
