It gives the world an opportunity to enter the world of oinks and squeals, and understand the psychological behavior of pigs. This can help farmers monitor the mental health of animals by tracking their behavior.<\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"text-align: justify; margin: 0cm 0cm 8pt;\"><span style=\"font-size: 11pt;\"><span style=\"line-height: 107%;\"><span style=\"font-family: Calibri,sans-serif;\"><span lang=\"EN-US\" style=\"font-size: 12.0pt;\" xml:lang=\"EN-US\"><span style=\"line-height: 107%;\">The researchers, co-led by Dr Elodie F Briefer, an Associate Professor at the University of Copenhagen, Denmark, and an animal communications expert, trained a neural network to identify and classify pig calls as being positive or negative. They used sounds pertaining to different stages of a pig\u2019s life cycle, from birth till death, to build the algorithm. For the study, they collected audio samples of pigs from various setups such as farms, commercial settings, and mock setups with toys, food, and random things to explore and play around with. Observing pig calls in different situations and scenarios helped them understand varied and nuanced emotions. <\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"text-align: justify; margin: 0cm 0cm 8pt;\"><span style=\"font-size: 11pt;\"><span style=\"line-height: 107%;\"><span style=\"font-family: Calibri,sans-serif;\"><span lang=\"EN-US\" style=\"font-size: 12.0pt;\" xml:lang=\"EN-US\"><span style=\"line-height: 107%;\">What comes across as mere grunts and snuffles is actually an entire book of emotional expressions, the study results indicated. The algorithm differentiated the calls that represented happy moments (such as getting close to other pigs or reuniting with families) from negative situations (such as fighting, or getting castrated).<\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"text-align: justify; margin: 0cm 0cm 8pt;\"><span style=\"font-size: 11pt;\"><span style=\"line-height: 107%;\"><span style=\"font-family: Calibri,sans-serif;\"><span lang=\"EN-US\" style=\"font-size: 12.0pt;\" xml:lang=\"EN-US\"><span style=\"line-height: 107%;\">Researchers associated high-pitched sounds with fear and anxiety, and low-pitched sounds with various situations across the scale. \u201cIn the positive situations, the calls are far shorter, with minor fluctuations in amplitude,\u201d<sup>2<\/sup> said Dr Briefer.<\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"text-align: justify; margin: 0cm 0cm 8pt;\"><span style=\"font-size: 11pt;\"><span style=\"line-height: 107%;\"><span style=\"font-family: Calibri,sans-serif;\"><span lang=\"EN-US\" style=\"font-size: 12.0pt;\" xml:lang=\"EN-US\"><span style=\"line-height: 107%;\">With more recordings and advanced research on the subject, the researchers hope to dwell deeper into animal psychology and focus on the mental wellbeing of animals. Dr Briefer emphasized the need for the algorithm to be turned into an app that will help farmers identify the animals\u2019 needs and work on them.<\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"text-align: justify; margin: 0cm 0cm 8pt;\"><span style=\"font-size: 11pt;\"><span style=\"line-height: 107%;\"><span style=\"font-family: Calibri,sans-serif;\"><b><span lang=\"EN-US\" style=\"font-size: 16.0pt;\" xml:lang=\"EN-US\"><span style=\"line-height: 107%;\">References:<\/span><\/span><\/b><\/span><\/span><\/span><\/p>\n<p style=\"text-align: justify; margin: 0cm 0cm 8pt;\"><span style=\"font-size: 11pt;\"><span style=\"line-height: 107%;\"><span style=\"font-family: Calibri,sans-serif;\"><span lang=\"EN-US\" style=\"font-size: 12.0pt;\" xml:lang=\"EN-US\"><span style=\"line-height: 107%;\">1.
