Prioritizing research that maximizes welfare improvement per research dollar guides effective allocation of the limited resources available for farm animal welfare science.
Farm animal welfare research prioritization requires thinking about expected welfare impact per research dollar. Species produced in enormous numbers — chickens, pigs, fish — merit research investment proportional to their scale. Basic welfare research identifying needs must be complemented by translational research developing practical farm-implementable improvements. Research on fish and invertebrate welfare is dramatically underfunded relative to their numbers. Research with clear policy application — providing evidence for regulatory standards — generates higher welfare returns than research without implementation pathways. Supporting research that advances welfare understanding for neglected high-volume species, develops practical assessment tools, and informs evidence-based policy represents the highest-impact investment in welfare science.
