Among the elements that are often overlooked is the microbiota, a true "invisible organ" that plays a key role in the health, immunity, and productivity of pigs. Understanding its dynamics and how it becomes imbalanced is increasingly essential for the success of health and nutrition programs.

Initial injuries at the tip of the ear are usually due to chewing behavior, while injuries at the base of the ear appear to be influenced by feeder-related bites.

To complement the necropsy course, we have produced a series of videos of different processes in pigs.

The flu is very much in the media spotlight, so we wanted to find out how much our users know about influenza's role in pigs and humans. To do this, we conducted a mini survey among our users.

In addition to its role in protein synthesis, tryptophan contributes to the production of serotonin, a molecule that influences appetite and immune system regulation, and niacin production.

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.

Inside the genome of the African swine fever virus: a giant that is difficult to decipher. CEREP uses genomics to study the virus's circulation in Italy and beyond.

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

We answer frequently asked questions from the public regarding the recent measures implemented to control the outbreak of African swine fever detected in wild boars in Barcelona, ​​Spain.

Almost four years after the first case of African swine fever was detected in Italy, the epidemic continues to pose a complex challenge for the country's health and wildlife management. Since January 2022, the virus has appeared in four distinct geographical areas. These were independent introductions of certain anthropogenic origin, occurring at different times and environmental contexts.

ASF has never spread so widely across the globe. The question is not if it will arrive, but when. The latest outbreaks detected in Europe may provide valuable information as the wolf lurks.

Increased productivity has not come without consequences. Sows face greater physiological demands, which translates into a higher metabolic load, increased nutritional requirements, and, in many cases, increased mortality on farms. This phenomenon is of particular concern in Spain.

Assessing lung lesions at slaughter is useful for monitoring their evolution over time, and thus estimating the effectiveness of the measures implemented to control these diseases.

The choice of cut-off point influences sensitivity, specificity, and the occurrence of false positives or negatives. We explain why the timing of collection and the purpose of the test make a difference in interpreting the results.

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.

High sensitivity, specificity, and an affordable cost make ELISA an indispensable tool in laboratory routines. This infographic explains the mechanisms, components, and main variations of this assay in a visual and objective way.

By exploring the mechanisms of the Common Mucosal Immune System (CMIS), orally administered vaccines are capable of activating coordinated immune responses across different mucosal sites in the body. In this content, we explain how local activation in the GALT triggers protective effects in distant mucosal tissues, such as the respiratory tract, thereby expanding the reach of immune protection.

In healthy animals, PCV2 stays under the radar, causing little harm. But with coinfections that activate the immune system, the virus replicates more and becomes more damaging.

We need a container for syringes, needles, medicine bottles, sprays, and markers. Sometimes you see improvised and inadequate containers on farms, but the one presented here is very simple and functional.

Chronic inflammation is one of the main challenges in modern pig production, affecting intestinal health, productive performance, and feed efficiency. In light of increasing pressure to reduce antibiotic use, functional nutrition emerges as a key tool.

Professor Nauwynck has been researching PCV2 virus since the emergence of PCV2-associated diseases. PCV2 caused a serious crisis in global swine health that was ultimately addressed through the development and mass deployment of effective PCV2 vaccines. He is an excellent connoisseur of this small virus that continues to surprise us.

Digestive diseases in pigs that were previously addressed individually, targeting a single pathogen, now form a digestive disease complex that we must confront from various angles.
