Organic farming standards require higher welfare practices than conventional systems, but the welfare benefits vary significantly by species and need to be evaluated critically.
Organic farming generally improves animal welfare through requirements for outdoor access, lower stocking densities, and restrictions on painful mutilations. Organic pigs with access to outdoor rooting areas show fewer tail-biting injuries and more natural behaviour. Organic laying hens range more freely and show lower rates of feather pecking. However, organic does not automatically mean high welfare: some organic operations provide token outdoor access that animals rarely use, and disease management challenges in organic systems can create their own welfare problems. Certification should be accompanied by genuine on-farm welfare assessment.
