Environmental enrichment — providing animals with opportunities to perform natural behaviours — is one of the most cost-effective welfare improvements available to farmers. Understanding enrichment principles helps advocates and producers.
Environmental enrichment is one of the most actionable and evidence-based welfare improvements available in farm animal management. The principle is straightforward: animals have behavioural needs shaped by millions of years of evolution, and denying those needs causes frustration, stereotypies, and chronic stress. Providing low-cost enrichment materials — straw for rooting, nesting boxes for hens, brushes for cattle — allows expression of natural behaviours with measurable welfare benefits and often production benefits. Corporate welfare commitments should include specific enrichment provisions, and farm assurance schemes should require rather than merely recommend enrichment.
