ArticleAre we letting our guard down with African swine fever? Are we ready for when the wolf comes? (2/2)
Considering the spread of African swine fever (ASF) globally in recent years, are we prepared for this increased risk?
Join the "Precision Production of Pigs – Unlocking Profitability Through Managing Variation" webinar
On Wednesday, November 19th at 11:00 CDT (17:00 CET), we invite you to attend this free webinar that will explore how variation in pig performance impacts profitability across the pork supply chain.

Are we letting our guard down with African swine fever? The wolf is at the door (1 of 2)
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.

ArticleSow mortality on Spanish farms: Key factors and strategies for improvement
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.
With historic results, the 333 Experience Congress LATAM 2025 comes to a close
The 333 Experience Congress LATAM 2025 successfully concluded its sixth edition in Cali, Colombia, establishing itself as the most important technical and business event for Latin American pig farming.
Pigs developed to be resistant to classical swine fever (CSF)
Pigs gain resistance to classical swine fever through gene editing, offering hope for protecting livestock against costly viral disease.
333 attends Vietstock 2025 in Ho Chi Minh City

ArticleEvolution of lung lesions in recent years: What information can we learn from this?
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.
How does the cut-off point affect the interpretation of ELISA test results?
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 immunity against viral challenges
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.
Fundamentals and mechanisms of the ELISA test
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.

This work presents a systematic review of the available scientific literature on the long-distance airborne transmission of PRRSV. Final thesis at the College of Veterinary Medicine, UAB, Spain, advised by Enric Mateu.
Health restart: the power of depopulation and repopulation to restore profitability
When losses and costs from poor health threaten the current and future farm profitability, perhaps a “clean slate” should be considered.
333 was present at the Tanzania International Pig Conference 2025 in Dar es Salaam
Tanzania International Pig Conference and Expo 2025 was held on 11th-12th July, 2025 and was attended by swine producers, veterinarians, industry leaders, swine companies, and international guests from several African countries.

Oral vaccines against respiratory diseases: activating the common mucosal immune system
Oral vaccination in pigs, previously limited to enteric pathogens, is emerging as an innovative strategy against respiratory diseases. By building on the potential of the Common Mucosal Immune System (CMIS), new formulations can trigger immune responses in distant mucosal sites starting from the gut.
Activation of the common mucosal immune system by oral vaccine
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.
What do you think about...?
Do you think ASF will break in your country in the next 3 years?
We already asked you this questions three years ago. In some countries, the disease was already present; in others, it entered during this time; and some remain free of it. We believe it's time to reassess the level of confidence in your country's biosecurity.
Feeding the enemy: more coinfections lead to more lymphoblasts, increasing the chances for PCV2 to replicate
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.
Tip: How to make a syringe holder
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.
