Chronic pain in farm animals is widespread, systematically underrecognized, and undertreated, representing one of the most significant welfare gaps in animal agriculture.
The scale of chronic pain in farm animal populations represents one of the most significant unaddressed welfare problems globally. Pain that persists across days, weeks, or months causes sustained suffering that fundamentally impairs quality of life. In farm settings, this pain is often unrecognized because it is expressed subtly: through slight behavioral changes, reduced movement, altered facial expression, and modified social behavior. Stockpeople trained to look for these signs dramatically increase treatment rates. The multiple barriers, lack of tools, cultural attitudes dismissing farm animal pain, economic pressures, and veterinary access limitations, are surmountable but require systemic attention. Closing the chronic pain recognition and treatment gap in farm animals would deliver one of the largest improvements in global animal welfare achievable in the near term.
