In a fascinating leap towards understanding our porcine pals, scientists have developed an AI tool capable of decoding pig sounds.
While it may not be quite on par with Doctor Doolittle, this algorithm is a significant step towards interpreting what pigs are "saying" and could greatly enhance animal welfare on farms.
The research, a collaborative effort by scientists from Denmark, Germany, Switzerland, France, Norway, and the Czech Republic, involved analysing thousands of pig sounds recorded in various scenarios such as play, isolation, and food competition. The study revealed that these sounds—grunts, oinks, and squeals—are not just random noises but indicators of the pigs' emotional states. For instance, short grunts are typically associated with positive emotions, while long grunts and high-frequency squeals often signal discomfort or stress.
Elodie Mandel-Briefer, a behavioural biologist at the University of Copenhagen and co-leader of the study, emphasises the importance of understanding animal emotions for their welfare. "Emotions of animals are central to their welfare, but we don't measure it much on farms," she notes. The AI tool could change that by providing farmers with a way to monitor and respond to the emotional well-being of their pigs.

Interestingly, the study also found that pigs raised in outdoor, free-range, or organic environments, where they have the freedom to roam and dig, produce fewer stress-related sounds compared to those raised conventionally. This insight could pave the way for new farm labelling systems, enabling consumers to make more informed choices based on animal welfare standards.
Looking ahead, the researchers envision a future where farmers could use a smartphone app to translate pig sounds into emotional cues, allowing for real-time monitoring and improved care. This innovative approach not only promises to enhance the quality of life for pigs but also aligns with growing consumer interest in ethically sourced food products.
In essence, this AI tool represents a remarkable blend of technology and animal behaviour science, offering a glimpse into a future where understanding and improving animal welfare is just a click away. So, the next time you hear a pig grunt, remember: it might just be sharing its feelings with you!
