How training programs that teach farm workers to recognize animal pain improve welfare outcomes across livestock species.
Pain recognition training is one of the most cost-effective welfare interventions available for livestock systems - relatively modest education investments produce lasting improvements in the welfare of large numbers of animals. The mechanism is straightforward: stockpeople who can recognize pain earlier treat it earlier, reducing the duration and severity of suffering for each affected animal. Across a career of livestock management, improved pain recognition skills benefit thousands of animals. The development of validated, practically usable assessment tools has made pain recognition education specific and teachable rather than dependent on vague intuition. Investment in this training at industry scale would produce welfare improvements that dwarf more expensive infrastructure investments.
