The attitude and skill of the stockperson is one of the most powerful determinants of farmed animal welfare — good stockmanship reduces fear, injury, and disease, while poor stockmanship causes suffering independent of facility design.
Stockmanship quality is a welfare variable that operates independently of facility design. A barren shed can be managed with kindness; an enriched facility can be managed with indifference or cruelty. The human-animal relationship shapes animal welfare through daily interactions that accumulate across an animal's entire life — small acts of roughness or gentleness repeated thousands of times determine whether an animal's experience of humans is primarily fearful or neutral. Training programmes that successfully change stockperson beliefs about animal sentience have documented welfare improvements, making this one of the most tractable welfare interventions available without facility investment.
