The evaluation of injuries and culls at the slaughterhouse provides a reliable and objective way to assess the welfare status of broiler chickens at the end of the production cycle. As animal-based measures (ABMs), these indicatiors reflect the conditions experienced by the animals on-farm, including handling practices, housing quality, and health management. By systematically collecting and analysing this data, farmers can identify recurring issues, trace them back to specific practices, and adjust their management accordingly. This feedback loop is a powerful tool to complement on-farm observations, strenghten animal welfare monitoring, and drive continuous improvement. Incorporating slaughterhouse data into regular welfare assessments helps producers move from reactive to proreactive welfare management, aligning with both regulatory expectations and societal concerns.
