A growing body of research has established which enrichment approaches genuinely improve livestock welfare versus which merely create an appearance of improvement.
Not all enrichment is created equal. Research has clearly identified the enrichment approaches that genuinely meet animal behavioral needs versus those that satisfy regulatory requirements without improving welfare. Straw beats chains for pigs; functional perches beat inadequate ledges for hens; edible foraging materials beat inert objects for cattle. Policy and certification standards must specify effective enrichment, not just any enrichment.
