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.

Spanish slaughterhouses are between a rock and a hard place. The heat will accentuate the supply shortage. Pig prices are increasing or staying the same, pork prices are decreasing, and consequently, margins are deteriorating.

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.

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....

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.

This is how to assemble an "emergency" ramp using the insulation panels left over from the construction of the nursery.

The global swine industry is dynamic and constantly advancing. One of these advancements is the significant increase in sow productivity. This is evidenced by the increase in the number of piglets born and, consequently, in the number of piglets weaned. This progress also poses new challenges, especially regarding the most important superfood on the farm: porcine colostrum. This leads us to ask if improving colostrum quality is possible through specific nutritional strategies.

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.
