Manipulable enrichment objects are essential for pig welfare, yet implementation quality varies enormously across farms. Research identifies which materials and designs best meet pigs' behavioral needs.
The welfare value of enrichment lies in its ability to satisfy pigs' strong drive to root, explore, and manipulate their environment. When enrichment fails to meet these needs - because it is too simple, too small, or too familiar - pigs redirect frustrated behaviors toward pen mates, causing injury. Farms that invest in high-quality, varied enrichment consistently report lower rates of tail biting and vet intervention costs. The evidence is clear: meaningful enrichment is both an ethical necessity and an economic benefit.
