AI tool decodes pig emotions for farmers

European scientists have developed an AI algorithm that can interpret pig sounds to help farmers monitor their animals’ emotions, potentially improving pig welfare. The tool, created by researchers from universities across several European countries, analyses grunts, oinks, and squeals to identify whether pigs are experiencing positive or negative emotions. This could give farmers new insights beyond just monitoring physical health, as emotions are key to animal welfare but are often overlooked on farms.

The study found that pigs on free-range or organic farms produce fewer stress-related calls compared to conventionally raised pigs, suggesting a link between environment and emotional well-being. The AI algorithm could eventually be used in an app to alert farmers when pigs are stressed or uncomfortable, allowing for better management. Short grunts are associated with positive feelings, while longer grunts and high-pitched squeals often indicate stress or discomfort.

Researchers believe that once fully developed, this technology could not only benefit animal welfare but also help consumers make more informed choices about the farms they support.
