PRRSpective project outlines a clear and simple plan for improving swine health management. Speakers Daniel Linhares, Clayton Johnson, Lance Mulberry, and Marius Kunze present actionable steps for achieving success through structured decision-making processes and disease control strategies.

Diagnostic tools should be implemented not only reactively during outbreaks, but also proactively, allowing for early detection of infectious agents to anticipate potential problems.

Thorough monitoring and a highly practical contingency plan helped minimise the impact of a PRRS infection at a GTC.

The post-ASF scenario will most likely paint a picture with fewer pigs and the unfortunate absence or disappearance of a number of operators.

Effective PRDC control isn’t a single protocol — it’s a system. Success depends on accurate diagnosis, tailored vaccination, strong biosecurity, smart production flow, and, above all, consistent implementation. As Cano said, “Execution is everything. The best protocol won’t work if no one’s watching the barn.”

In this second instalment, Cano and Segalés talk about tools for detecting PRDC on farms, the factors influencing its development, and vaccination.

Jean Paul Cano, a veterinarian with extensive field experience in US and now in Spain, provided practical field insights into managing PRDC in production settings. Joaquim Segalés, UAB professor and CReSA researcher, offered an academic perspective and share the latest findings on PRDC pathogenesis.

Tonsil scrubbing using sponge catheters demonstrates a greater capacity for virus detection compared to sera from infected sows.

Boosting key performance indicators in swine production requires addressing viral pathogens, which remain a major challenge for swine health, performance, and farm profitability. Emerging strains, such as H1N2#E and devastating diseases like ASF, highlight the urgency for innovative control strategies. C12 monoglycerides represent a promising approach to enhance pigs’ immune defenses and mitigate viral impact.

When losses and costs from poor health threaten the current and future farm profitability, perhaps a “clean slate” should be considered.

PRRS control measures also reduce the opportunities for different wild-type viruses to recombine and create more aggressive strains.

Genetic mutation and evolution of PRRSV can occur across all genes. Unlike ORF5, which only represents about 4% of the PRRSV genome, NGS can recover a whole PRRSV genome to be used in epidemiological investigations.

The first three years of the Danish PRRS reduction strategy have shown that it is possible to control and reduce the prevalence of PRRS in Danish pig production.

In the first two months, the outbreak caused more than 600 abortions and more than 150 sow deaths, destroying the weekly batch structure.

The last of the three summaries by Antonio Palomo dedicated to the 2024 edition of the Allen D. Leman Conference focuses on health: biosecurity and viral and bacterial diseases.

We analyze the two most relevant respiratory viruses in the swine population.
