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.

Reducing costs in pig feed formulation depends not on a single action, but on the strategic integration of multiple factors: precision in formulation, ingredient selection, use of technologies, and efficient management of the nutrition model and purchasing.

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.

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.

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.

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.

One of the major challenges during weaning is post-weaning diarrhea, impacting nearly 25% of piglets in European countries. A promising strategy to boost resilience and help piglets navigate the stress of weaning can be, among others, the use of phytogenics.

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.

Mammals, such as pigs, have a keen attraction to sweet tastes. They are able to perceive the five basic tastes: umami, sweet, bitter, sour, and salty. Sugars such as sucrose, glucose, and lactose are especially attractive to them. This trait seems to have evolved as a natural mechanism for detecting high-calorie energy sources.

In 2024, the Latin American swine industry continued to show outstanding performance, reaffirming its potential, resilience, and capacity to adapt to the challenges facing the sector in a complex market environment. However, given the current geopolitical circumstances, reconfiguration of international pork trade flows in Latin America is expected in 2025 as a result of retaliation against the tariffs imposed by the United States.

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.

Uniformity and quality play a key role in the success of both the feed mill and the farm. The quality of swine feed starts with proper diet formulation, which must meet the animal's nutritional needs at every stage of its life, and a proper mixing process ensures uniform nutrient distribution and directly impacts production performance, animal health and welfare, and economic efficiency.

The relatively short but very intense lactation period is undoubtedly a key phase in pig production for both sows and piglets. The fragility of the piglets and the significant demands that sows face at this stage make early detection of problems essential. Do we understand what the animals are telling us?

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.
