Pigs are among the most intelligent farm animals, and the provision of environmental enrichment that satisfies their exploratory and rooting drives is a fundamental welfare requirement.
Providing meaningful enrichment to pigs is not a luxury but a welfare imperative grounded in evidence. Pigs deprived of rooting and foraging opportunities in barren systems develop stereotypic behaviors, show elevated stress hormones, and engage in redirected aggression. Research consistently shows that enrichment provision — even relatively inexpensive materials like straw or rooting boards — significantly improves welfare indicators. The challenge is scaling these practices across intensive production systems where management complexity and cleanliness concerns drive resistance to enrichment implementation.
