When foetuses develop in a heat-stressed gestation sow, a condition known as in utero heat stress occurs, and piglets may be born smaller with impaired gut microbiome and immune function. Additionally, these piglets show greater susceptibility to stress later in life. Although these consequences are not always immediately apparent, they are important to manage and prevent.

We're not just talking about family succession. We're talking about talent, vocation, future. How to cultivate today the leadership the sector will need tomorrow.

The virus detected in Barcelona is ASF genotype II and has been classified in a new genetic group: #29.

The most common diseases in piglets caused by E. coli are colibacillosis and edema disease.

The post-ASF scenario will most likely paint a picture with fewer pigs and the unfortunate absence or disappearance of a number of operators.

Short-chain fatty acids (SCFAs) and medium-chain fatty acids (MCFAs) play a key role in intestinal health in pigs. In addition to providing readily available energy, they contribute to microbiota modulation, pathogen reduction, and improved digestibility and nutrient absorption, specially in piglets during the post-weaning period.

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.

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.”

Spain has flooded the EU with cheap pork. Low pork prices dragged down prices in some countries.

Intestinal immunity is a complex system composed of physical barriers, immune cells, receptors, and microbiota.

Joaquim Segalés, UAB professor and CReSA researcher, offered an academic perspective and share the latest findings on PRDC pathogenesis.

Tryptophan (Trp) is an essential amino acid that pigs must obtain from their diet. It is involved in protein synthesis and serotonin production, which regulates appetite. It also contributes to the formation of niacin (vitamin B3) and has antioxidant effects, promoting intestinal health and microbiota. In addition, it helps maintain mucosal integrity and regulates the immune system.

Vitamins are essential for proper growth and also for ensuring proper function of the nervous system, immune system, reproductive system, bone development, and cell repair. They do not provide energy, and each vitamin performs particular functions that none of the other vitamins can.

When losses and costs from poor health threaten the current and future farm profitability, perhaps a “clean slate” should be considered.

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.

August brought a welcome breather to the German pig market.

A stew of grains with an abundance of ingredients, but seasoned with risks that could sour the overall dish.

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.
