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.

Unusual drop in July and August of more than 17 cents, and it is expected to continue to fall.

After weaning, endogenous hydrochloric acid production is still limited, which raises stomach pH and compromises pepsin activity, affecting protein digestibility and favoring pathogen growth.

This second article from the WelfarePIGnet project describes practices for improving pig access to feed and drinking water, including the costs of implementing them.

The opportunities are real, but several challenges are holding the industry back.

How does heat stress affect animal growth and meat quality?

When we manage errors systematically, we stop punishing symptoms and start addressing the real causes.

Pigs are particularly vulnerable to heat stress due to their limited ability to dissipate body heat and genetic selection for higher productivity, which has reduced their heat tolerance. Improved technical results increase heat production, and today's lines produce 30% more heat than those in the 1980s.

Guillem Burset explains the reasons for the exceptional drop in pig prices in Spain during July.

In this installment, we will discover how heat stress affects the digestive tract of pigs.

Genetic improvement is key in livestock production, playing an essential role in achieving a modern, efficient, and sustainable pig production model.

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.

Implementing precision feeding through the use of electronic feeders improves sow and piglet performance while providing economic, environmental, and animal welfare benefits.

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.

Hans Nauwynck defines himself as a veterinary virologist, a person who works in a laboratory setting, doing precise work, like a surgeon, aiming to gain a better understanding of how animal viruses interact with their target cells. But it is much more. His deep understanding of the biological behavior of viruses allows him to fluently explain many of the “whys” that are so important for a better understading of the pathogenesis of viral diseases and the development of effective control strategies.

Communication in the swine industry today faces a double challenge. On the one hand, there is a real need to transparently show the sector's work to an increasingly distrustful consumer, who is either uninformed or saturated with emotional messages. On the other hand, we must do so in a changing digital environment, which rewards the authentic, the emotional, and the useful.

This is how one of the Tosh Pork farms in the United States works, combining technology, production efficiency, and social commitment. In this first article, we present the structure, work culture, and overview of U.S. swine production.

Who talks about inflammation? We all might mention it when we exercise too much – aching joints, stiffness – or is it just we are all getting older…? But we do not really talk about inflammation much. And certainly, when we think about our livestock, we do not really mention it at all. Well…we should.

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

In this commentary, we review various issues affecting the swine market: the blackout in Spain, corporate concentration, the evolution of carcass weights, Trump's policy....

The pig price in Spain is well above the rest of the European countries. The reality is that this price is only possible at the expense of negative margins in the slaughterhouses.

The pig industry in Africa holds great potential as a key driver for food security, income generation, and rural development. However, it faces several challenges that hinder its growth and sustainability.

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.

Do we know how to communicate the main objective of correct data collection? What clues can make us suspect that the data are not being properly recorded?

For pigs to grow and be productive, their nutrition must provide the intake of energy and nutrients necessary for maintenance and production. The most important nutrients are proteins, fats, minerals, and vitamins. Ingested and recycled proteins will be used for tissue growth and repair, enzymatic and hormonal functions, transport of substances, immune responses, water and electrolyte balance, muscle contraction, cell signaling, and pH maintenance.

During a recent visit to a pig farm in Sweden, 333 had the opportunity to learn first-hand about the Moving Floor system, an innovative technology for improving pig welfare and reducing emissions.

Of the pillars of commercial pig production, nutritional management, is based on its impact on the total final production cost. In Brazil, it represented 73.16% of the total production cost in 2024 on average, according to data from CIAS (2024, EMBRAPA). In this way, constantly updating the energy and nutrient requirements needed to optimize production outcomes is a focus of attention and a goal of ongoing scientific research.

In this last article in the series we discuss the main causes of “vaccine failure”, i.e. when we aren't sure that vaccines are working or they are only partially working.

In today's context of high production costs and increasing pressure from environmental regulations, swine production faces the challenge of balancing production efficiency with the environmental and economic sustainability of the industry. A key factor in this equation is feed particle size, where simple actions available to the producer can achieve significant improvements.

At the risk of being proven wrong by the end of 2025, we will try to break down what we think this year has in store. It's not about using a crystal ball, but rather analyzing the data we already have and weighing its importance. At the end of the year, you can compare and see whether we got it right or missed the mark.

The price of pork has remained well above the cost price throughout the year, with declines from the peak (1.848 euros per kilo in July) being gradual and controlled, allowing slaughterhouses to navigate the autumn with favourable positive margins.

To identify the keys to success in managing sows in breed and release systems, France's Chamber of Agriculture of the Brittany Region surveyed farmers who implemented this system. The results identified three strategies that producers use the week after weaning.

Beta glucans can boost the vaccinal response, thus helping to achieve an optimal vaccinal response. If they are supplied during enough time to cover the whole vaccination programme this strategy could be an option to improve the vaccine response.

Histopathology can provide a strong framework to establish the real causality of a clinical problem.

Nutrition plays a major role in the immune response. The interaction of different dietary components with other factors such as environment, health status, and genetics plays an important role in modulating the immune response.
