Porcine Reproductive and Respiratory Syndrome is more commonly known as PRRS. According to studies done by Iowa State University, it’s the most economically damaging disease to the U.S. pork industry. Extension Swine Outreach Specialist Jeff Morris says it’s estimated that PRRS cost producers $1.2 billion in 2024.
Pigs can contract the disease at any time throughout their lifecycle. However, Morris says the most detrimental effects happen when sows contract the disease. “The biggest and the most significant thing is, if you’re a swine farmer with sows, that you’ll really see an increased number of abortions.” He mentions that an increase in stillborns and a decrease in sow fertility rate are also effects of the disease.
If producers see symptoms in their herd, and suspect PRRS, they are encouraged to work closely with their veterinarian. Leveraging a healthy vet-client-patient relationship throughout the diagnosis and treatment process It is generally recommended to collect samples and run diagnostics to determine if PRRS is present, and, if so, which strain. There are numerous variants within the complex of PRRS virus, so it is crucial to identify which one.
Morris explains that, unfortunately, there is no reliable treatment for PRRS. Instead, he encourages an approach of prevention. “When you have visitors, and also your employees, to make sure that they are doing strict biosecurity protocols for your specific farm. Some is as simple as disposable boots when you enter the facility.”
