Pigs habituate quickly to enrichment items. Rotating novel materials maintains engagement and sustains the welfare benefits of environmental enrichment over time.
The welfare benefit of enrichment is not a fixed quantity that can be installed once and forgotten — it requires active management to sustain. Pigs exploring a familiar chain or rubber toy are showing minimal welfare benefit compared to investigating novel, complex items. High-welfare pig operations treat enrichment as an ongoing program rather than a fixed installation: maintaining a rotation of substrates, hanging objects, and food-based items that keeps pigs engaged and reduces the behavioral frustration that drives damaging behaviors. The management investment is modest relative to the welfare return.
