Protecting Your Pigs from Aujeszky’s Disease: Symptoms, Treatment, andPrevention

Aujeszky’s disease — commonly known as pseudorabies — is a devastating swine disease that can significantly impact the productivity and health of your swine herd. Protecting your pigs from Aujeszky’s Disease not only safeguards their health but also your economic stability as a swine farmer. This article will delve into understanding the symptoms, treatment, and prevention of Aujeszky’s Disease.

What is Aujeszky’s Disease?

Aujeszky’s disease is a highly contagious viral disease caused by the Suid Herpesvirus 1 (SuHV-1). While it primarily affects swine, it can also infect a range of other animals, including cattle, sheep, dogs, and cats. This disease is often fatal in animals other than pigs, underlining the importance of managing and preventing its spread.

Symptoms of Aujeszky’s Disease

Identifying the symptoms of Aujeszky’s Disease is vital for early detection and management. Clinical signs can vary depending on the age and immune status of the pig:

  • In piglets: Sudden death, fever, vomiting, and neurological signs like shaking, paddling, and convulsions.
  • In growing pigs: Respiratory distress, fever, anorexia, and often, although not always, nervous signs.
  • In adult pigs: Respiratory signs, fever, anorexia, and in pregnant sows, abortions, stillbirths, or weak piglets can occur.

Remember, prompt detection of these symptoms can greatly assist in managing the disease.

Diagnosing Aujeszky’s Disease

Aujeszky’s disease is diagnosed primarily through laboratory testing. This can involve virus isolation, PCR, ELISA, or serological testing. Consult with your local veterinarian or animal health authority if you suspect your pigs might be infected.

Treatment of Aujeszky’s Disease

Unfortunately, there is no known cure for Aujeszky’s Disease. Instead, treatment focuses on reducing stress in the affected animals, providing supportive care, and controlling secondary infections. Infected animals should be isolated to prevent the spread of the virus to other animals.

Preventing Aujeszky’s Disease

Prevention is the most effective method to protect your pigs from Aujeszky’s disease. Here are key steps to consider:

  1. Biosecurity Measures: Ensure that your farm has strong biosecurity measures in place. This includes preventing contact with wild animals, controlling people’s access to your pigs, and practicing good hygiene.
  2. Vaccination: Regular vaccination is crucial. While it doesn’t prevent infection, it reduces the severity of the disease and limits virus shedding.
  3. Monitoring and Testing: Regularly monitor the health of your pigs and conduct disease surveillance tests. Early detection can prevent a full-blown outbreak.
  4. Quarantine New Animals: Newly introduced animals should be quarantined and tested for the disease before integrating them into the herd.
  5. Immediate Reporting: If you suspect your pigs might have Aujeszky’s Disease, report it immediately to your local veterinarian or animal health authority. Prompt action can limit the spread of the disease.

The Economic Impact of Aujeszky’s Disease

“The economic toll of Aujeszky’s disease can be significant, leading to loss of livestock, decreased productivity, and increased costs for disease management and control.”

Protecting your pigs from Aujeszky’s Disease is not just a matter of animal health; it’s also a matter of financial health for your farm. By understanding the disease, its symptoms, treatment options, and preventative measures, you can take the necessary steps to safeguard your swine herd and your farm’s economic stability.


Aujeszky’s Disease can be a daunting challenge for any pig farmer. However, armed with the right information and strategies, it’s a challenge that can be successfully managed. It’s vital to maintain a proactive approach — regular health checks, strict biosecurity, and preventive measures can make a substantial difference in protecting your pigs from this disease.

Remember, maintaining a healthy and productive swine herd requires an ongoing commitment to their welfare. Keep vigilant about potential diseases, work closely with your veterinary professionals, and ensure that your biosecurity measures are always up to scratch.

By being aware and proactive, you can provide a safe and healthy environment for your pigs, thereby protecting your livelihood from the devastating effects of Aujeszky’s Disease.
