Pig health

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.

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

Initial injuries at the tip of the ear are usually due to chewing behavior, while injuries at the base of the ear appear to be influenced by feeder-related bites.

To complement the necropsy course, we have produced a series of videos of different processes in pigs.

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.”

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

In this second instalment, Cano and Segalés talk about tools for detecting PRDC on farms, the factors influencing its development, and vaccination.
