Understanding the full range of natural pig behaviour reveals the scale of behavioural deprivation in commercial production systems and motivates more comprehensive welfare standards.
The contrast between natural pig behaviour and commercial production conditions is stark when explicitly enumerated. Natural pigs forage for hours, roam extensive areas, maintain complex multigenerational social bonds, wallow, play and nest-build. Commercial pigs rarely or never engage in these behaviours. This comparison is not sentimental — it reveals the scale of motivational frustration built into current production systems. Welfare improvement means narrowing this gap through enrichment, space provision, longer maternal contact and social complexity, not merely preventing the worst acute harms.
