The development and application of positive welfare metrics for farm animals, moving beyond suffering prevention to actively measuring thriving.
The development of positive welfare metrics represents a conceptual maturation of animal welfare science that has direct practical implications. When we measure only the absence of suffering, we miss the dimension of animal experience that may be most important: whether life is actively good rather than merely endurable. Positive welfare metrics capture play, exploration, social engagement, and cognitive optimism — states that indicate animals are not just surviving but genuinely thriving. Building these metrics into certification schemes, regulations, and farm management tools creates a higher aspiration for animal agriculture than suffering prevention alone: the aspiration for animals to experience genuine wellbeing within whatever system contains them.
