In the heart of Indiana, a 5,000-head sow farm faced a critical challenge when acute reproductive issues emerged, particularly affecting the gilts. The farm witnessed concerning clinical signs, including early farrows, late aborts, weak-born piglets, and an alarming rate of mummies. Immediate action was imperative to identify and address the root cause of the symptoms. Understanding the urgency, our team quickly initiated a comprehensive diagnostic investigation. Samples were diligently collected and tested for pathogens that are known to cause reproductive issues in swine, including Porcine Reproductive and Respiratory Syndrome (PRRS), Porcine Circovirus type 2 and 3 (PCV 2/3), and Porcine Parvovirus. The diagnostic results revealed a positive diagnosis for Porcine Parvovirus-1, underlining the detrimental effects this pathogen has on reproduction.

Upon analyzing the situation, it became apparent that a gap existed in the vaccination protocol of the affected gilts. This specific cohort of gilts might not have received the requisite vaccine or the appropriate dosage, leading to their susceptibility to Porcine Parvovirus. The team swiftly devised a strategic vaccination plan to combat the outbreak and safeguard the future reproductive success of the herd. Pregnant gilts were promptly administered with a single dose of the vaccine, while open gilts received two doses as a preventive measure. Furthermore, incorporating mummy feedback in the Gestation-Diagnosis-Ultrasound (GDU) process was deemed crucial to monitor and manage any potential outbreak recurrence.

Thanks to the proactive intervention and meticulous execution of the vaccination strategy, the farm witnessed a remarkable turnaround in just a few weeks, and normal production resumed. The collaborative efforts between farm management and our veterinary team ensured the outbreak was effectively contained and the herd's health and productivity were restored to optimal levels.

The Porcine Parvovirus outbreak was a stark reminder of the critical importance of vaccination protocols in safeguarding swine health and productivity. Through swift diagnosis, targeted intervention, and diligent monitoring, the farm not only overcame the crisis but also fortified its defenses against future outbreaks. Moving forward, continued vigilance and proactive adherence to vaccination protocols remain paramount in ensuring the sustained well-being of swine herds. Remember, prevention is always better than cure. Stay informed, stay proactive, and safeguard the health of your swine herd.
